In the next figure it is possible to see the internal printer architecture and where the major blocks described below are located. ### ### ### ### ### MECHANICAL ASSY PRINT HEAD CABINET ELECTRONIC HARDWARE INKED RIBBON Fig. 1.3 Printer Internal Architecture GENICOM 3460 / 3480 / 3480+ 1.7 GEK-89537 Maintenance Manual Overview General 1.2.3.1 Mechanical Assy This block is composed of a rubber platen roller with a carriage carrying a print head with 9 needles (3460 model) or 24 needles (3480/3480+ models) in front of the platen. This movement is obtained via a step-motor (providing 1/120" movement per step) and a minipitch belt. The movement of the rubber drum for paper traslation is obtained via a specific step motor providing a minimum movement of 1/144" for 9 needle model or 1/180" for 24 needles model and a couple of minipitch belts. The motion of the ribbon cartridge is obtained through a specific step-motor indipendently from the actual carriage speed, movement, direction and width. In this way in front of the print head there is a continuously renewing well inked ribbon. The ribbon speed is optimized to reduce conflicts with ribbon and graphic printout appearance when ribbon and print head are moving in the same direction. The color ribbon and the extended life black cartridges are moved up and down through a linear actuator (step motor) with a plastic coupler that transmits the axial movement to the plastic print head mask installed on the color ribbon cartridge. Another step motors is used for the A.G.A. (automatic gap adjustment) of the print head movement to have the best perfomance on the paper in use. The printer is able to increase/decrease the strength of the needle stroke via MENU (selectable by User) to allow a high impact force also for multi-part forms (up to 7 copies). 1.2.3.1.1 Tractor Unit Assy A removable push-pull tractor unit is installed on the printer. Inside of it, a DC motor switches to engage/disengage the gear to allow the fanfold or the single sheet to be fed. The tractor unit can be installed in two different positions depending on the type of fanfold management (front - rear - both). In the next chapter all the paper handling possibilities of this mechanism are detailed. 1.2.3.2 Print Head The core of the printer is the print head, which is for both models an electromagnetic non- ballistic type with a life of 400 MChrs. There are three different print heads: 9 needles for 3460. 24 needles for 3480. 24 needles for 3480+. 1.2.3.3 Cabinet The cabinet allows safety-proof lifting of frontal part for ribbon substitution and paper path check. It is composed of various parts to allow an easy access to all the printer internal parts. GENICOM 3460 / 3480 / 3480+ 1.8 GEK-89537 Maintenance Manual Overview General 1.2.3.4 Electronic Hardware This section is composed of the following boards: MAIN BOARD located in the bottom right side of the printer which controls the motors movement, the various input sensors, the parallel interface and the print head needles. It also provides the management of the asynchronous host serial interface, external synchronous serial interface for mechanical options and fonts cartridge. POWER SUPPLY BOARD located in the bottom left side of the printer which provides specific voltages for logical area, printhead needles and drive motors. There are two power supply boards: 120 and 220/240 Vac respectively. OPERATOR PANEL BOARD placed on the front side of the printer driving 9 push buttons and 8 leds (3 for printer status and 5 for paper path selection). This board also drives a 16 Digit LCD Alphanumeric display to easily interact with parameters setting for menu operation. SERIAL INTERFACE board located on the rear right side and plugged to the main board which drives the proper drivers for serial interface. 1.2.3.5 Inked Ribbon Cartridge The ribbon cartridge is installed in different ways according to the ribbon types. In case of the black ribbon, the cartridge is fixed on both sides on four points. Its position is obliquous to the print line to automatically show the complete height of the ribbon in front of print head while printing on the full print line. The inked ribbon inside of these cartridges is a continuous loop. In case a color ribbon or an extended life black ribbon installed, the cartridge is fixed on both sides only on the two rear points, so that is is free to move its frontal part upward and downward. Its installation is parallel to the print line to assure the correct color band selection. A specific step motor is used to move the ribbon band up and down for color selection. 1.2.3.6 Mechanical Options This printer can provide some mechanical options : AUTOMATIC SHEET FEEDER (up to 3 bins). Each bin has a DC motor inside it to automatically load the single sheet paper. Internally on the bin a series of gears takes the movement of the motor to the rubber roller shaft. Together with the first bin a PAPER STACKER is provided to collect the output printed paper. Also this part has an internal step motor to select the path where the paper should be output.

Moreover, the mechanism has been designed to be, first of all, ergonomic for a better and easier end-user operation. 2.1.1 Paper Handling Architecture All the paper paths described below can co-exist and can be selectable via MENU and SW commands. The printer automatically switches from one path to the other except for the rear pull tractor positions. Via operator panel menu it is possible to select one format per each path (up to 6) or a single format (equal for all paths). The basic configuration provides these ways to manage the paper formats: (In the next figure the paths for continuous modules are indicated as , while the paths for single sheet forms are indicated as --->; each path is identified with a number). ### SINGLE SHEET A semi-automatic frontal single sheet insertion (PATH 1). The single sheet forms are manually loaded in this path. When a sheet is inserted, the sensors detect its presence and the printer loads the paper automatically without any other action. ### CONTINUOUS MODULE (FANFOLD) Through a user installable/removable tractor unit the fanfold module can be fed through the following positions: FRONT PUSH mode (PATH 2) with tractor group in position A, also overlapped with single sheet (PATH 1). REAR PUSH mode (PATH 3) with tractor group in position B, also overlapped with single sheet (PATH 1). REAR PULL mode with frontal insertion (PATH 4) with tractor group in position C, also overlapped with single sheet (PATH 1), exclusive with fanfold in PATH 3. REAR PULL mode (PATH 4) with tractor group in position C, with input from the bottom (PATH 5), also overlapped with single sheet (PATH 1) exclusive with fanfold in PATH 3. For the first two paths, the continuous module exits from PATH 10. GENICOM 3460 / 3480 / 3480+ 2.2 GEK-89537 Maintenance Manual Overview Paper Handling ### DOUBLE FANFOLDS Through the optional second user installable/removable tractor unit the following feeding positions for continuous module are available : DUAL PUSH fanfolds mode. The first fanfold from the front in push mode with basic tractor group in position A (PATH 2), the second from the rear in push mode with optional tractor group in position B (PATH 3), both overlapped with a single sheet (PATH 1). For this path, the fanfolds exit (once at a time) from PATH 10. PUSH&PULL fanfolds mode in which the fanfold can be fed from the front in push mode with the basic tractor group in position A (PATH 2) and at the same time is pulled from the second tractor group in position C (PATH 4). Also this configuration can be overlapped with a single sheet (PATH 1). ### AUTOMATIC SHEET FEEDER (ASF) Through the optional Automatic Sheet Feeder the following feeding positions for single sheets are available : REAR in the first bin (PATH 6). REAR in the second bin (PATH 7). REAR in the third bin (PATH 8). Inside the paper output stacker, a mechanical switch allows the alternance between the output single sheets, which are collected to the output stacker (PATH 9), and the fanfold using this exit (PATH 10). On the next figure 2.1 it is possible to see the internal architecture of this printer in which the different paper paths handled by the new design of the mechanical assembly are put in evidence. On the table 2.1 it is possible to find the Paper Path Types that can be selected according to the printer Path Configurations.

RIGHT SIDE On the right side of the printer, the paper motor (1) drives a series of gears and feeder assy through the main paper belt (5) . Directly connected through the paper motor gear, there is an idle gear (2) which gives the motion to the front push-pull tractor assy idle gear (4). The tractor gear (3) is engaged-disengaged on the tractor idle gear (4) through a linear movement done by the push-pull tractor assy motor. The main paper motor belt also drives the platen assy pulley gear (9) and the lower feeder assy gear (7). A movable idle (5) is present to give the proper belt tension. A second belt called platen belt (10), takes the motion from the platen assy internal gear and drives the upper feeder assy gear (11). The support spring rollers (8) and the pinch rollers of the bail assy (12) assure the correct paper feeding from the manual front path and the out of platen area respectively. See chapter 2.2 for the manual actions for opening the pinch rollers. LEFT SIDE On the left side the upper feeder assy gear (11) gives the motion to the rear push-pull tractor assy through a couple of gears and to the paper stacker gear (15). A manual lever engages the tractor idle gear (4) in two possible modes: - through the movable gear (14A) for the rear push path action. - through the idle gear (13) the movable gear (14B) for the rear pull action. Chapter 2.2 shows the rear tractor push-pull lever action. The tractor gear (3) is engaged-disengaged on the tractor idle gear (4) through a linear movement done by the push-pull tractor assy motor. A specific motorized roller (18) is present on each ASF to feed the paper sheet up to the friction rollers (17). On this side there is also the mechanism which automatically opens and closes the friction rollers located below the platen assy (17) when the rear push path is choosen. This action is done through a combined movement of the carriage motor and the paper motor. When the friction rollers must be moved, according with the selected paper path, the carriage motor moves the carriage unit to the left-most position, causing the movement of the friction lever assy and the engagement of the open gear (9) to the sector gear (16). At this point, a paper movement slides the the friction bar assy with the sector gear splined to its shaft (16) to the proper open or closed position.

It is important not to move the carriage and paper advance knob manually to change the friction bar position because this would cause the loss of the correspondance between mechanism position and the sensor tuning . If any intervention of this kind has been done, it is indispensable to run the T&D to assure the correct correspondance.

The figure 2.5 shows the Front Load Push-Mode of the fanfold. The figure 2.6 shows the Rear Load Push-Mode of the fanfold. The figure 2.7 shows the Rear Load Pull-Mode of the fanfold (alternatively the paper can enter in the bottom feed slot). For all these paper paths, it is possible to overlap a single sheet. IMPORTANT REMARK ### For the REAR PUSH mode, the fanfold must have a maximum thickness of 0.35 mm instead of 0.635 mm of the other paths. ### For the REAR PULL mode, a manual intervention is necessary. The bail assy must be lifted (upper position) and the selection slider located on the left side of the printer must be in its up position to assure the correct rotation of the rear tractor (see chapter 2.2.5 or user manual for major details).

The paper sensors are reflecting type. They are driven by the main board in a dynamic mode. This means that the input led is driven by the + 5 Voltage with an impulse wave to increase its life. The output signal enters in an analog multiplexer and then to the analog to digital converter port of the microprocessor (see figure 3.12). The sensors are adjusted at manufacturing site with a proper T&D tool which stores these output voltage levels of the three sensors detected with NO PAPER installed. This value is stored in NVM on main board. If the main board or if some parameters of these sensors are changed (due to their lifeparameters degradation or simply a different shining printer location), this level may not be correct anymore for the normal operation of the printer. Also if the mechanical assy has been disassembled in the friction bar assy part, check the coherence between the position of this part and the values stored in NVM (see chapter 6.4). Check all these aspects and, enventually, readjust and memorize these values. The procedure can be executed in two modes: ALWAYS WITHOUT ANY PAPER INSERTED IN ALL PATHS. ### At FIELD level, the test is automatically executed in the T&D 11 test (this is the first test of the mechanism). ### At USER level in the INITIAL SET-UP Menu.

In this chapter it is possible to find also some helps to test printer and to identify defective components using the Test & Diagnostic facilities. For all other aspects regarding the printers setting and printer programming, please refer to the following manuals: • • • Model 3460/3480 User's manual (P.N. GEK-89170) Model 3460 Programmer's manuals (P.N. GEK-89212) Model 3480 Programmer's manuals (P.N. GEK-89213) First-level maintenance is based on F.R.U. (field replaceable unit). GENERAL REMARK Pay attention to turn the printer off, unplug the power cord and wait for at least 5 minutes before starting with the cleaning operations due to the high temperature on some mechanical parts when the printer is on normal operation from a long time (print head, carriage motor, paper motor). Install the power supply cover tool if a printer maintenance is done when the printer is powered on (see chapter 6.3.3). 6.2 Initial Ispection When the printer presents a trouble, before proceeding to the service maintenance, an initial inspection must be done. In fact, a problem in the printout often is due to a bad or wrong condition of the printer itself. The parameters that must be previous checked are: set-up, cleaning, paper specification. After that, if the problem remains, a troubleshooting session can be activated. 6.2.1 Set-Up Check for the following items to make sure they are fullfilled. ### Is the printer placed in a correct position ? ### Is the environmental temperature in the nominal range ? ### Is the relative humidity in the nominal range ? ### Is the unit installed in a bad location ? (Close to high temperatures or humidity, near heat sources, dusty areas, areas where gas is generated, exposed to direct sunlight) ### Has the printer a good configuration ? GENICOM 3460 / 3480 / 3480+ 6.2 89537 GEK- Maintenance Manual Maintenance Service In the OPERATIONAL MENU under the PRINT STATUS item it is possible find three different menu listings : SYSTEM, CONFIG and FORMAT. Please refer to the user manual for more details on all these items. 6.2.2 Cleaning No preventive maintenance, on a schedule basis, is required. Periodic cleaning will help to keep your printer in top condition. Clean the printer as follows: ### Use a neutral detergent or water solution on a soft cloth to clean dirt and grease from the cabinet of the printer. ### Do not use an abrasive cloth, alcohol, paint thinner or similar agents because thay may cause discoloration and scratching. ### Do not LUBRICATE the main and rear shaft, but only clean dirt. ### Be especially carefull not do damage the electronic and mechanical components. Check for the paper paths condition and to make sure they are correct. If they are dirty (by paper residues or by ink), please clean them using a soft cloth. 6.2.3 Paper Specifications Also the paper is important to have high performances. Check for the correct paper specifications. See chapter 1.3 and the USER manual for more details. 6.2.4 Consumables Genicom reccomends to use only its original consumables with original packaging. In this way, a proper use of the printer at the quality level and reliability stated in the product characteristics can be assured. All typical usage problems typically related to not certified consumables can be avoided, such as: an overall degradation of the printing quality level and often, the reduction of the total life of the product due to the fact that the proper working conditions of the print head and other parts are not assured. Moreover, the original consumables are controlled in compliance with the international standard rules concering: ### no cancerous materials ### no inflammability of the plastic materials GENICOM 3460 / 3480 / 3480+ 89537 6.3 GEK- Maintenance Manual Maintenance ### other standard Service GENICOM 3460 / 3480 / 3480+ 89537 6.4 GEK- Maintenance Manual Maintenance Service 6.3 Troubleshooting Guide The recommended sequences for the printer fault detection are: ### To observe initializing procedure and Operator Panel messages. ### To check power malfunctions. ### To run the SELF-TEST procedure. ### To run the T&D (Test and Diagnostic) procedure. ### If necessary, run the HEXADECIMAL dump procedure. At any stage where appropriate, refer to the troubleshooting guide. 6.3.1 Initializing Phase When the printer is powered on, before starting the normal operations, it performs an initializing phase (BOOSTRAP). During this phase the Software of the printer initializes the hardware resources of the printer for the correct function. ### The display will show: STARTING UP and then performs a full-matrix display check from leftmost to rightmost position. ### The display will show : ################################################ After a successfull initialization phase, the printer enters in the normal operation phase, moves the carriage assy on the left most position to check the home position sensor and goes in READY or WAIT state, depending on if the paper is already installed or not. If the printer does not initialize correctly see next chapter to see the possible error messages displayed on the LCD. 6.3.2 Printer Errors Some errors can be displayed by the printer.

The T&D program can also be considered as a software tool to support the production activities. It has been realized in order to avoid the shipment of printers not perfectly operating. 6.4.2 T&D Structure The software architecture of this printer is composed of one layer called as "PLATFORM", which has the task to manage the interfaces towards the existing H/W resources, and an "APPLICATION" layer which contains modules for emulations management. The T&D provision is an application module and uses the PLATFORM to accede the H/W resources (engine, operator panel, nvm, etc.). Under diagnostic conditions the whole RAM is checked to assure that there are no errors in the area in which the Operating System will be allocated. For this purpose, it has been stated that the portion of diagnostic procedure carrying out these tests, should be executed at system's BOOTSTRAP. If, and only if bootstrap tests give positive result, the PLATFORM module and the diagnostic application will then be initialized. At this point, subsequent tests will be executed (NVM, plugs, printouts, etc...). 6.4.3 T&D Kit A specific card of T&D card is issued with P.N. 78399178-001. The FW of the T&D card includes: ### ### ### complete code for all the tests described in the next chapter module for standard printout adjustment for 1st line, tear-off, vertical printing Together with this card three loop-back must be installed: The 232 serial loop-back connector The 422 serial loop-back connector The mechanical options loop-back connector The parallel loop-back connector P.N. 78403675-001 P.N. 78403676-001 P.N. 78403674-001 P.N. 78401829-001 GENICOM 3460 / 3480 / 3480+ 89537 6.24 GEK- Maintenance Manual Maintenance Service 6.4.4 Execution of User T&D The USER T&D is the T&D procedure for the field level maintenance. It requires the following: ### ### ### The T&D card plugged onto the right side slot provided in the cover. MFG jumper on operator panel board must be absent as default setting. The serial interface 232 and parallel interface loop-back connectors must be installed in the serial and in the parallel interface connectors. The mechanical options loop-back connector must be installed in the paper stacker connector. Insertion, before starting test, of some forms (136 characters, 72 lines) of fanfold module on the front tractor path. Press simultaneoulsy ON LINE and PAPER ⇓ keys at power on for at least 2 seconds. ### ### ### All tests indicated in the table 6.1 are one-shot or automatically sequential executed depending by the first choice after the initialization phases (see chapter 6.4.6 ). At the end, sample forms are printed out for all electromechanical checking and mechanical adjustments. During the execution of each test, the display will show some messages to show to the technician the activity in progress or the action the operator has to do in that moment. NOTICE : ### It is indispensable that no paper modules are present in any paper paths when the T&D procedure is executed (the sensors must be not covered by the paper). In fact, the T&D automatically adjusts, whitout any intervention, all the reflective sensors of the printer (single sheet, front fanfold, rear fanfold). ### The cover must be closed, otherwise a message "# COVER OPEN " displayed. will be GENICOM 3460 / 3480 / 3480+ 89537 6.25 GEK- Maintenance Manual Maintenance Service 6.4.5 Loop-Back Connectors The T&D can check also the functionalities of various I/F's existing on the printer. A proper loop-back connector must be used to have the correct feed-back. Three connectors are used for the following intefaces: ### Serial Interface loop-backs. They are composed by some wires that connect the output signals with the input signals of these interfaces, one for the RS232 and the other for RS422 type. See figure 6.5A and 6.5B for diagrams. ### Parallel Interface loop-back. It is composed by some wires that connect the output signals with the input signals of this interface plus an intergrated circuit (parallel latch) that provides the correct handling of the bidirectionality of the data input/output lines. See figure 6.6 for diagram. ### Mechanical Options loop-back. This loop-back must be inserted in the connector located in the upper right side of the mechanical assy in which the paper stacker assy must be inserted.

Table 6.5 T&D Error Codes 6.4.10 Tests Description T&D 0 - RAM MEMORY TEST This test is executed during system bootstrap if diagnostic condition is present. The whole ram which is used by the Operating System module is checked. If this test fails, the T&D is halted with no possibility to go ahead. T&D 1 - HARDWARE / SOFTWARE MATCH TEST This test checks if the eproms present on the main board are of the proper type with respect to the respective board (for 9 or 24 needles). T&D 2 - CONTROLLER EPROM MEMORY TEST This test executes the CRC with 31-degree polynomial, which involves the whole memory addressing (512 KB x 8 = 4 Mb). For a positive test issue, the computation must be 0. During the test the display shows "T&D 2 CRC ROM *". A flushing asterisk indicates the correct running of the test. T&D 3 - FONT/EMULATION EPROM MEMORY TEST This test executes the CRC with 31-degree polynomial, which involves the whole memory addressing (256 KB x 8 = 2 Mb). For a positive test issue, the computation must be 0. During the test the display shows "T&D 3 CRC CARD *". A flushing asterisk indicates the correct running of the test. T&D 4 - GENERATOR EPROM MEMORY TEST This test executes the CRC with 31-degree polynomial, which involves the whole memory addressing (512 KB x 8 = 4 Mb). For a positive test issue, the computation must be 0. During the test the display shows "T&D 3 CRC FONT *". A flushing asterisk indicates the correct running of the test. T&D 5 - OPERATOR PANEL BOARD TEST This test consists of a first reading, which checks for 9 keys to be opened. If one key is damaged (short circuit), an error message is displayed and the T&D is halted. After that, the test checks all the 8 leds of the printer. All these leds are lit and then off, then sequentially from right to left one led is lit for about 0.5 second with an associated buzzer sound. GENICOM 3460 / 3480 / 3480+ 89537 6.40 GEK- Maintenance Manual Maintenance Then the test continues with a request to push sequentially the 9 keys from right to left. The display shows the message "PUSH KEY 1 --->" to indicate that the rightmost key should be pressed. Then, at every step the display shows the message "PUSH KEY (n)". If the wrong key is pressed, the buzzer sounds twice to advise the error. In case that the requested key is not activated within a few seconds, an error code is displayed.

For further details, refer to the Section dedicated to the diagrams of the loopback plugs in this chapter. T&D 11 - SENSOR TUNE RIBBON, COLOR MOTOR, RIBBON WELD and REAR FRICTION STATUS TESTs SENSOR TUNE This test is executed just before any mechanical movement (T&D 11 to T&D18 and eventually T&D20), so the T&D11 is the first impacted test. If one of these tests is skipped, the rear friction status check appear in the next one. This test is automatically done by the T&D program without any manual intervention. REMARK! Before running this test remove, if present, the paper from any paths. FRICTION STATUS This test is executed just before any mechanical movement (T&D 11 to T&D18 and eventually T&D20), so the T&D11 is the first impacted test. If one of these tests is skipped, the friction status check appear in the next one. The last test is to verify and change, if necessary, the coherence between the internal NVM data for the Friction Bar Position and the relative mechanical position of the bar itself. As described in chapter 2, in this printer there is an automatical movement of the friction GENICOM 3460 / 3480 / 3480+ 89537 6.41 GEK- Maintenance Manual Maintenance rollers for the rear fanfold path.

Information passing through the interface can be described in three separate aspects (levels): 1- Physical and electrical characteristics which enable the transferred signals to be recognized by both devices that are talking each other. 2- Link protocol signals and rules enabling and maintaining the connection and the transfer of data to be recognized and interpreted by both devices. 3- Device protocol the "language" which allows different products to give the same meaning to the transferred information. Refer to the USER MANUAL for all the recognized commands. 8.1.1 Hot Interfaces All physically available interfaces are simultaneously connected to systems. When one is operating, the other interface(s) are busy unless the input memory reserved for that interface has space enough to receive characters. To each interface an emulation is associated (by the operator) changing the interface parameters also the emulation environment. If there is not enough memory to store the complete environment, changing the interface in case of different emulations will reset the printer, including DLL data. The interface is reserved as soon as a first character is received, and until 10 sec. are passed after the end of any printing activity without receiving any characters (any type, including service, commands etc). 8.2 IEEE 1284 Parallel Interface The hardware of the parallel interface implemented in this printer is able to support the IEEE 1284 interface, even if the actual level of FW is not able to manage it. This interface is a bi-directional extension of the existing personal computer parallel interface (commonly known as the CENTRONICS interface). The bi-directional communication occurs using the signals of the currently interface. This new interface has been issued due to the limitation of the actual standard parallel interface with respect to the new PC environment. The serial port provides bi-directionality but does not offer enough bandwidth. The Standard parallel interface (Centronics) offers a higher but limited bandwidth and no bidirectionality. Centronics also requires a lot of assistance from the host CPU making it inadeguate for environments like Windows where multiple applications are running simultaneously. FEATURES 1) This interface provides the capability to send data from the host to the peripheral device at higher speed than it was possible before. This is accomplished by shortening the signal timing values where possible. 2) This interface provides a path for data to be sent from the peripheral device to the host using existing and future parallel port hardware. 3) The reverse channel capability reduces the amount of user interaction needed to operate the peripheral device. GENICOM 3460 / 3480 / 3480+ 8.2 GEK-89537 Maintenance Interfaces For example, application program can ask a printer for a list of fonts currently available. The application can then decide if new fonts must be downloaded, rather than asking the user to do it. Manual GENICOM 3460 / 3480 / 3480+ 8.3 GEK-89537 Maintenance Interfaces Manual 8.2.1 Communication Modes The IEEE1284 interface supports a number of distinct communication modes, and the interpretation of interface signals depends on the current mode. ### Compatibility mode (Centronics) This is the lower level mode which provides an asynchronous, byte-wide forward (hostto-peripheral) channel with data and status lines used according to their original definitions. In this mode, the host sends 8-bit bytes to the peripheral device over the interface data signal D1 ... D8. ### Nibble Mode This mode provides an asynchronous, reverse (peripheral-to-host) channel, under control of the host. In this mode, peripheral device to host data bytes are sent as two sequential, four-bit nibbles using the four peripheral-to-host status lines. This mode is used with Compatibility mode to implement a bi-directional channel. These two modes cannot be active simultaneously. ### Byte Mode This is the higher mode supported by the printer. It provides an asynchronous, bytewide reverse (peripheral-to-host) channel using the eight data lines of the interface for data and the control/status lines for handshaking. This mode is used with Compatibility mode to implement a bi-directional channel with transfer direction controlled by the host, when the host and the peripheral both support bi-directional use of the data lines. These two modes cannot be active simultaneously. The highest interface mode can be selected via Menu: in this way the interface can be limited to: Centronics, Bidirectional Nibble, Bidirectional Byte. 8.2.2 Operating Phases Interface operation is divided into different interface phases. Each communication mode consists of one or more phases. Additional phases are defined toward initialization and transitions between communication modes. The names and interpretations of the interface signals may vary between phases, but are consistent within each phase. Compatibility Mode Phases Compatibility Mode Forward Data Transfer phase. This phase begins when the host asserts nStrobe and ends following data hold time and nStrobe de-assertion (the host is not free to send the next data until the device acknowledges the transfer using nAck). The host may not initiate negotiation to a new operating mode until the interface returns to Compatibility Mode Forward Idle Phase. Compatibility Mode Forward Idle Phase The interface is in Compatibility mode with no data transfer in progress. The host may initiate a data transfer in Compatibility mode, or may initiate negotiation to a new operating mode. GENICOM 3460 / 3480 / 3480+ 8.4 GEK-89537 Maintenance Interfaces Manual GENICOM 3460 / 3480 / 3480+ 8.5 GEK-89537 Maintenance Interfaces Nibble and Byte Mode Phases Reverse Data Transfer phase. Data transfer from peripheral to host. Reverse Host Busy Data Available phase. The peripheral has data to transmit. Reverse Host Data Not Available phase The peripheral has no more data to trasmit. Reverse Idle phase No data transfer in progress, the host is waiting for device data. When data is available, the peripheral will cause the interface to go to the Reverse Interrupt phase. Reverse Interrupt phase This phase provides the mechanism for the peripheral to alert the host that it has data to transfer. While in this phase, the host may cause the interface to go to the Termination Phase. Manual Additional Phases Initialization phase This phase includes both power-on initialization and host-driven interface reset. Negotiation phase Signal handshaking to change the signaling method from Compatibility Mode to Nibble or Byte. Termination phase A host-initiated transition phase in which the interface is changed from Nibble or Byte to Compatibility. 8.2.3 Negotiation This interface is self adapting to the same mode as the system to which it is connected, also if it is not IEEE 1284 compliant. This means that a IEEE 1284 compliant host negotiates with the peripheral device to determine whether or not the device is 1284 compliant by checking its status lines to include PError and nFault both at logic high levels for a particular host stimulus. (n Selectin set high in conjunction with host busy being set low to request a 1284 mode). Together with this stimulus, the IEEE 1284 interface protocol has been designed to allow the host to request that the peripheral device uses various communication modes. This is accomplished by the host placing an extensibility request value on the data bus during the negotiation phase. The value 00h means Nibble Mode, while the value 01h means Byte Mode The printer answer on Xflag signal to this value. The Xflag affermative response is LOW for Nibble Mode, HIGH for Byte Mode.
