Paper quality Light pulp paper of medium fine quality, paperbearing the quality mark SM Post and photocopypaper are suitable for use. Unsuitable are:satin-finish or coated papers, imitation art papers,

and embossed papers.Since paper as natural material reacts strongly toenvironmental influences (e.g. humidity,temperature), the place of storage should beselected carefully. We recommend that this kind ofpaper should be tested extensively before largerquantities are acquired.Should papers with a dark reverse side be used,these should also be tested for their functionality.Please pay attention to the use of infrared reflectingcolors, when acquiring these papers.

3 Functional Description

3.1General

3.1.1Printhead The printhead is rated to more than 300.000 standard pages. The printer is

economical too: 12.000 standard letters are printed with one ribbon.

With our own word-wide patented 24 needle technology the printer also in speedreaches the top region of its class, with its noise level being in the lower range. Theprinter practically operates in conjunction with all known computer systems andstandard software.

3.1.2Power Supply The power supply may be switched by the user externally from 120 V to 230 V. A

fuse (T4,00AH250V, UL) is provided to protect the power supply from hazardousdamages. It can be replaced without opening the printer.

3.1.3Ribbon The quality of the printout is dependent on the quality of the ribbon. Therefore the

ribbon as well as the printhead are very important parts of your printer.

A used ribbon cannot deliver a satisfactory printout. To achive a long life duration forthe ribbon always use it in its full width. This will be achived by moving the ribbon upand down during printing and rotating the ribbon in the infinite end ribbon cassette.

The ribbon is therefore satisfactory used and reaches a long life time.With a color printer you must decide if a color ribbon for a color printout or a mono-chrome ribbon for a one color printout is to be used.In the first case the color ribbon, which can have up to four tracks, is vertically movedin four steps in relation to the printhead, depending on the selected color.

If you want to achive a monochrome printout with a color printer, you should use amonochrom ribbon and set the parameter black in the Setup menu Color Opt..The firmware moves the color ribbon, simular to a standard printer, in four verticallevels. Because of this electrical control the monochrom ribbon is optimally used by acolor printer.

3.1.4Data Transfer The main difference between the serial and parallel interface is the form in which the

data bytes are transfered. The serial interface transfers bits in a row, one after theother. Theoretically you only need three connections for this form of data transfer. Inthe parallel interface the data transfer of the 8 bits (1 byte) is completedsimultaneously through 8 parallel connections. At least 11 connections between thecomputer and the printer are necessary for this procedure.

With the parallel Centronics interface data up to 100.000 bytes /seconds theoreticallycan be transfered. Actual the printer opperates with a maximum transfer frequency ofapprox. 30.000 bytes/second. This Data Flow, depending on the adjustment of theinput buffer (0-128 KB) on your printer, can be temporarily stored.

3.1.5Monitoring The most important functions are monitored with sensors, microswitches and

electrical monitoring circuits. These are constantly checked, processed by an internallogic and indicated on the display.

To prevent an overheating of the printhead, 12 coils of the 24 electromagnets aremonitored. If the temperature reaches a value above 130 C the speed of the printeris automatically slowed down. As soon as the printhead has cooled the printer workswith high speed again.

If a coil becomes defective, this is recognized by the firmware and shown on thedisplay (Head defect, THS Error, Head Hot permanently).

For safety reasons the top cover is also monitored. If you should open the top coverduring printing operation, then the printout is momentary stopped (to avoid injuries).When you close the cover again the printout is continued without loss of data.

3.2Mechanical Functions

3.2.1Head/PlatenClearance

The worm gear (see principle drawing) determine the basic head distance. You canimagine the worm gear as a mechanical memory. During initialisation (power up) ofthe printer the head distance stepper moves the toothed segment on block at theworm gear. Now the printer has its basic point and can count the steps forward whichare stored in the firmware. The stepper tolerance is within one bit pattern (equals 4steps).

3.3.1.1Description of theSwitching PowerSupply

To switch over from e.g. 120 V to 230 V the user only has to move the powerselection bar. To avoid unexpected switching, you have to use a tool, like tweezers,to switch over.The power supply conists of discrete and integrated circuits, transformers and otherelements. It is primary switched and therefore a small built power supply.

The value of the fuse is T4,00AH250V Slow Blow. Please note that a UL listedfuse must be used.

How to test the printersfunction without Mains

Input

There is the possibility to run a test procedure without line voltage. To perform thisrun following steps:

Disconnect printer from outlet and switch printer off Give DC Voltage (33 V) to jumpers connector x4 on the main board. If you supply the logic with 1 A DCyou are able to handle the panel, the motors

and the printhead (only moves) If you supply the logic with 3 A DCyou are able to make self test printout (e.g.

ASCII tree; no graphic printing please), also.

Described steps have to be carried out very carefully.

3.3.1.2

Driver Section This part is mainly claimed of the PPU 96 ASIC 47537.

This highly integrated circuit serves both to activate further actuators as well as torecognise and pick up sensors or status signals. This means that this IC sonsistsmainly of registers, latches and selective logic.

Also the motor drivers and the needle drivers are controlled by PPU 96.

3.3.1.3Needle Driver The needle driver signals (NOxx) are connected to the printhead via plug X14/X2 of

the connection board to the printhead adapter board. The following diagrams willshow the voltage/current relation, the flow of the current in several conditions and theprinciple of driver circuit.

The data transfer handshake (with some smaller exceptions)has been implemented according IEEE1284 standard. Up to now (13.12.95) only theNibble Mode was implemented (Bytemode, ECP-Mode and EEP mode may followlater per request). The Nibble Mode has been adapted to meet the requirementsMicrosoft Windows (TM) Operating System which does a printer identification usingPlugnPlay. A graphical schematic is shown in the IEEE1284 standard picture 3,page 25 and picture 9, page 35.

2 Detailed description of data transfer in Nibble Mode

The transmission of printer identification is divided into two parts. In the first phasethere is a negotiation between PC and printer to activate Nibble Mode. In thesecond phase there is a data transfer. At the end of each phase there is a reentry toto the normal Centronics mode according a defined handshake procedure. The nameNibble Mode in this case means that the transmission is performed in two packagesper 4 bit in direction to the PC using existing control lines (bit 0/4=Error, Bit1/5=Select, Bit 2/6=Paper-End, Bit 3/7=Busy). All other possible modes are using the8 standard data lines - now in the opposite direction (printer - PC)

2.1 Phase 1, Negotiation phase

Procedure

The PC sets SELECTIN to high and at the same time AUTOFEED to low. The printer reacts within 35ms with SELECT, ERROR and PAPEREND to high

but DONE to low PC transmits one data byte to the printer with a STROBE signal and sets

AUTOFEED to high This byte will be analyzed by the printer. If all seems to be ok this byte should be

00hex witch means the PC likes to know whether or not the printer is supportingNibble Mode.

Since the printer is able to run Nibble Mode the printer answers then withSELECT, ERROR and PAPEREND to low. To create an interrupt at PC side,

DONE will be set to high at the end. Now the termination of the negotiation phase will be done by setting SELECTIN

to low. As a result the printer is setting SELECT and BUSY to high and after a short

delay also SELECTIN to low. As a reaction AUTOFEED is set to low at PC side. The printer is now setting ERROR and SELECT in normal Centronics mode

according the actual state and after that DONE is changed back again to high. PC should react then setting AUTOFEED signal to high As the very end of this negotiation phase the printer sets BUSY and DONE in

normal Centronics mode according the actual state. Now everything is in normal state.

2.2 Phase 2, Data transmission phaseThis phase is activated even after phase 1. A string of characters is transferred from

the printer to the PC, which immediately describes the printer type, the manufacturer,the device class and some sort of compatibility.

Procedure

SELECTIN and AUTOFEED are set to low by the PC at the same time Within 35 ms the printer reacts with SELECT, ERROR, PAPEREND and DONE

set to low. PC transmits one Byte with a STROBE pulse and sets AUTOFEED to high This byte will be analyzed by the printer. If everything was ok the byte should be

04hex which means that PC is demanding the identification of the printer inNibble Mode. The printer agrees setting PAPEREND to low and DONE to high.

PC answers setting AUTOFEED to low.

Now the initial procedure starts by sending the characters. The string is built upin a way that the first two bytes are indicating the total length of the string(including the first two counter bytes). MSB first then LSB is transmitted followedby the characters.

Each byte starts by putting bits 0 - 3 to the control signals (see above). This Nibble (half - byte) is released setting DONE to low. The acknowledge of PC is done by setting AUTOFEED to high. As soon the printer recognizes the acknowledge DONE is put back to high. As a result the PC sets AUTOFEED back to low. Now bits 4 - 7 are sent using the signal lines. This Nibble (half - byte) is released setting DONE to low. The acknowledge of PC is done once more by setting AUTOFEED to high. As long as there are data to be transmitted the printer sets now PAPEREND,

ERROR, SELECT and BUSY to low and DONE once more to high. The acknowledge of the PC is performed by setting AUTOFEED to low. Now the next nibble can be sent and the procedure is repeated. If there are no more data to be transferred after the last Nibble (half - byte) the

printer is setting ERROR to high, SELECT, PAPEREND and BUSY to low. This will be release setting DONE to high. Now the termination of the data transmission phase is starting. The PC sets

SELECTIN signal to low. The printer reacts different than in the negotiation phase - with SELECT set to

low, BUSY set to high and - after a short delay - DONE set to low. The printer is setting ERROR and SELECT according to the actual status in

normal Centronics mode and after that DONE back to high.

PC reacts setting AUTOFEED to high. At the very end of the data transmission phase the printer sets BUSY and DONE

according to the actual state in normal Centronics mode. Now everything is in normal state again and the transmission of the printer

identification is completed.

General infomationabout external

interfaces

This printer has a bi-directional parallel Centronics type interface (accordingIEEE1284) which is mounted on the printers main board. As an option, the plug-in

interfaces of other pay be used. E.g. if someone wants to use an (optional) RS232(V24) I/O he has to use the combined MT3x0 serial/parallel I/O. Since this I/O alsohas an on-board Centronics type interface the built in interface must be switched off.(Please consider that there are interfaces without a parallel interface; i.e. TTY,RS422. Using this kind of interfaces will not switch off the bi-directional I/O.)

If an additional parallel I/O is added, it is mandatory to disable the internal CX

I/O on the main board, so that only the plugged-in parallel I/Os will be active.Otherwise the printer will misread data on the parallel data lines.

A shared serial/parallel (RS232(CX) I/O is possible, but two parallel I/Os are notallowed. To avoid this the CPU of this printer is monitoring a signal at the connector

for external I/Os to determine the presence of an additional to the standard parallelI/O on the main board. The signals name is PT0, it can be found at Pin 15 A of theexternal I/O connector. Please refer to the following table to determine the function ofPT0:

PTO in Volts Meaning

< 1.8 Volt the internal parallel (CX) I/O will be used

> 1.8 Volt 2.5 < 3.0 Volt the external parallel I/O will be used*

> 4.5 Volt the internal parallel (CX) I/O will be used

* Please consider that the external parallel interface may not support IEEE1284 (plugnplay).

Possible modification of existing and future external I/Os with own parallel interface:

3.3.3.2Shared Interface Your printer can be configured in such a way, so that it uses only one interface or

both alternatively. If only one interface is used, this is only monitored by the printer.If the printer is configured in such a way that both interfaces are used simultaneously,it alternately accesses the interfaces to see whether there are any incoming data. Ifthe printer recognises a signal, it switches to the corresponding interface and sendsthe ACTIVE signal to the other one. After data transmission has been completed,the printer remains assigned to the interface for as certain period of time (hold time:30 s). After this period has elapsed, the printer clears the buffer and the procedurebegins anew. If after this the current position is not at Top of Form a Form Feed willbe carried out.

CXThe parallel section is controlled by the main logic, only I/O Drivers (7407, 74244) arenecessary. Please see also section 3.3.3.1 General Information.

RS232C / V 24The serial part is controlled by the main logic only I/O Drivers (L 232 50P) arenecessary. They convert 5 V Input signals to RS232 Standard voltage (-12/+12 V).Several jumpers are prepared to customize the interface.

3.3.22Printhead There are two different printheads available:

NDK9/24 (approx. 1800 Hz max) NDK11/24 (approx. 2400 Hz max)

This modern ballistic printhead is driven by the needle driver section on the mainboard (FT5763M, signals N1xN24x).

The needle control is performed by the PPU96 (47537).

General:The system to shoot a needle is activated by a current through a coil of the system.One end of each coil of the needle magnet is connected to the voltage UN (+33) Vvia the head cable. The return lines of the other ends of the coils are connected to

the needle drivers of the driver board. In the needle driver chip; controlled by theprogram; the return lines are connected for a short time to GND. If the expectedneedle current is reached the current will be chopped by hardware control.

The printhead is connected to X2 and X14 on the Connection Board. (Take care notto loosen the pull relief clamp at the plugs when replacing printhead!).

3.3.24Theory of

Adjusting Print-head TemperatureT2170 and T2280only

The resistance of each coil of the printhead is proportional to its internal temperature.

The temperature will change almost linear to the measured coil resistance. Theresistance is measured continuously. Therefore it is possible to monitor the printheadfor highest performance but to protect it in case of overheating. This control systemmust be adjusted once in case of changing printhead or at changing main electronic(see chapter 6.3.1).

Used formula: R = Rt2(1 + )

= TemperatureR = Resistance

= 3,95 10-31

K

= Difference of Temperature (t1- t2)t1 = calculated temperaturet2 = adjust temperature

Example: The printhead was adjusted by 20C (t2).The measured resistance was 5 (Rt2).We want calculate the temperature (t1)at 7 (R).

(R

Rt2) 1

t1 = 102C + 20C 122C

= 102C

3.4Loading Firmware

(principle)

In the very first beginning a Firmware is released by development. After that the

Alpha test will check the firmware in a Flash controller. Since Eprom controller arenot supported only the Flash version will be checked and released by Alpha testdepartment. Afterwards the firmware will be distributed via Competence Center inform of a FLASH File (for flash memory) and mostly as a BINARY file (for eprom).A never initialized FlashMemory has to be burned once then the Bootstrap-Loader isresident in the memory. From then on the Memory is ready to being flashed.(Character set) needs not to be initialized first since the bootstrap loader remains inthe firmware socket).

Please see a chart which intends to clear up the actual situation:

4 Testmodes and Troubleshooting

The following internal printer tests are available:

ASCII tree 8 InchASCII tree 13.6 InchHex-Dump capabilityMonitoring function

For better understanding it is recommended to read also chapter 3 FunctionalDescription.

4.1Test Functions In order to test whether your printer is functioning properly, you can choose from a

selection of different test functions. With these tests you can check print quality,function of the printhead and mechanism as well as data transfer from computer toprinter.

To enter the test mode of the printer, keep the ON LINE button depressed whileturning on the printer. Keep the button depressed until the printer emits a shortacoustic signal.

The test menu offers you three test functions, one adjustment function and fivespecial settings which are described in the in the operators manual.

Note:The printer is equipped with the option of locking the menu, for example to prevent

others from accessing it. You can do this using the MenLockparameter from withinthe menu itself. (The MenLockparameter is described in detail in the menudescription table of the Operators Manual). You can access a locked menu byswitching on the printer while simultaneously pressing the SETUPbutton

4.1.1ASCII Tree With the ASCII tree test you can test whether your printer is functioning properly

(independently from your computer). You can select either 80 or 136 characters perline. For example, you can interrupt the test if you want to change the line density bypressing the On line button. To exit the ASCII test, the printer must be turned off.

Example for an ASCII test printout

4.1.2Interfacetest(Hex-Dump) With the interface test (hex-dump) you can check data transfer from computer to

printer. The text which is being transmitted to the printer is printed in two parts.In the left part the text is printed in hexadecimal format, and in the right in ASCIIformat.
