3.6 PROGRAMMING THE PRINTER FUNCTION

The printer settings can be modified by confirming or refusing via console a

series of parameters that are printed when the SET-UP mode is accessed.

To activate the SET-UP mode, proceed as follows:

- Turn OFF the printer and remove the sprocket.

- Press the FORM FEED and the LINE FEED keys and turn on the printer without

releasing them for about 3 sec.

- Insert a sheet of paper (manually with the paper feed knob

automatically with the FORM FEED key)

or

In this mode, the possible programming parameters will be automatically

printed, one at a time; at each alternative the operator will respond

pressing: the LINE FEED key (= YES) to confirm the proposed parameters, or

the FORM FEED key ( = NO) to choose a different parameter.

The programming procedure can be stopped at any time pressing the LOCAL key.

The programming menu ends with the message "WOULD YOU LIKE TO STORE THESE

PARAMETERS ?". Depending on whether you enter "YES" or "NO", the final

printout will be as follows:

- CHANGES EXECUTED if you enter "YES". In this case the new parameters you

have selected have been stored to the printer's EEPROM.

- NO CHANGES EXECUTED if you have entered "NO".

5. FAULT TRACING GUIDE

i i

n This chapters contains two flow charts designed to help less expert

] I technicians to trace printer faults.

n If the printer remains OFF: unplug the printer mains cable and where

possible plug it into another mains socket or plug another electrical device

that is know to be functioning correctly into the same socket.

In this way, you can determine whether the fault has occurred in the printer

P or is due to the local mains system.

If mains power is present, refer to the flow chart of page 5-2.

nI If the machine fails to print: check that the LOCAL LED is off. If this LED

is on, check that the sheet of paper has been inserted correctly.

"] If after making the above checks, the machine still does not print, make a1 local test on it.

H The printer can not perform a local-test or the Set-up procedure if the

I ! Computer connected by the serial interface (C64/128) is OFF.

p If the printer passes the local test, check the hardware setting of the

! | printer.

Also check that the parameters set on the system are coherent with those of

"1 the printer (interface, printer emulation, open mode, character set, ecc).

H8. ADJUSTMENTS

8.1 ADJUSTMENT OF PRINTHEAD-PLATEN DISTANCE

This adjustment must be made each time the printhead has been removed and

also when print quality deteriorates.

Fix the printhead in place using the two screws (1) so that the needles are

at 6.45 - 9.5 mm from the platen (2).

n

n

n

r

n

n

Note: A wider gap between the print head and the platen than that indicated

above will cause a deterioration in printing quality; if, however, the

gap is too narrow, the following drawbacks may be encountered:

- Tearing or mark on the paper

- Excessive wear on the needles and ribbon

- Irregular movement of the carriage

n 8-1


8.2 ADJUSTMENT OF THE STROBE DISK OF THE CARRIAGE

This operation must be performed each time the carriage motor, the encoder

group and the print group has been removed. The adjustment should also be

made in the case of carriage rebound at the end of its stroke.

To time the strobe disk contained in the encoder of the motor, proceed as

follows:

- power OFF the printer

- bring the print carriage to the left side of the printer (console side)

- disconnect the motor pinion

- turn the disk of the encoder so that its retention screw is in a

horizontal position, towards the direction of the electronic board.

Note: Incorrect timing of the strobe disk may cause blockage at the RH end

of stroke position of the carriage.

8.3 ADJUSTMENT OF THE PAPER DETECTOR PHOTOSENSOR

When you change the board, or you change the EPROM firmware

release, you oust perform the paper detector adjustment.

In order to perform this adjustment follow this procedure:

with a new

A. Press LOCAL and LINE FEED keys and turn on the printer without

them for about 10 sec.

This operation must carried out without paper in the printer.

The LOCAL led will blink now.

releasing

B. Press the LINE FEED key for about 2 sec.

The platen will performs a complete revolution.

The LOCAL led will blink rapidly now.

C. Insert manually a sheet of paper.

Press the LINE FEED key for about 2 sec.

The blinking stops and the printhead carriage moves to the left to

perform the reset. At this point the printer has written the output value

of the Photosensor in the EEPRON.

If the platen do not the revolution described on point B, switch OFF the

printer and cut the Rl resistor on the board (see board lay-out). Therefore

repeat the operations beginning from point A.

If the carriage do not move (point C), switch OFF the printer and cut the R2

resistor on the board (see board lay-out). Therefore repeat the operations

beginning from point A.

This adjustment allows you to and/or vary the sensitivity of the

Photosensor. The Rl works on the photoemitor diode, wheareas the R2 works on

the transistor (receiver). It is true that the regulation procedure provides

two cases, one of light and one of dark, but one excludes the other.

On following the procedure described, it is necessary to cut only one of the

res i s tor concerned.

Signal Description -,-,

The DATA STROBE signal is a negative pulse that transfers data into the I J

printer electronic circuits. The pulse duration must be longer than 866 ns. UThe circuit is pulled up with 1 kohm resistance to +5 V.

The eight DATA LINES circuits transmit data (characters or control codes)

from C.U. to the printer. The logical level of the data item to be r

transferred must be stable at least 866 nsec before the negative edge of the j"strobe" impulse and must remain stable at least 866 nsec after the positive <-ledge of the "strobe". These signals are pulled up with a 1 kohm resistance

towards the +5 Volts. j j

The INPUT PRIME signal is a negative impulse and can be used by the C.U. to .--;

reset the printer. The impulse must last for at least 16 msec. j I

The ACKNOWLEDGE signal is a negative impulse which is used by the printer to j Iindicate complete transfer of the character and that the next character can Utherefore be sent.

DThe BUSY signal is active at when high and provides the printer busy and

unable to receive data.

The PAPER EMPTY signal is active when high and indicates to the C.U. that . _

the paper is almost finished. | j

The SELECT signal is active when high and indicates that the printer has n

been selected and is ready for "data transfer". M

The FAULT signal is active when low and indicates to the C.U. that the j Iprinter is faulty. u

nE. COMMAND CODES

i !

Instructions for printing are sent to the printer in the form of bytes, i.e.

H groups of eight bits, transferred simultaneously through the cable

1 connection.

p The coding system used is called ASCII and is based on the relationship

j j between bits and characters (for example, the letter A correspond to thebyte 61990901). The equivalent code for each character is given in the

appendix F. To avoid always writing the full sequence of eight bits, decimal

H equivalents will be used; the number precedes the letter D, (A « 65 D), ori I the hexadecimal code - the number precedes the letter H (A = 41 H).

n Of the 256 codes available (6 t 155 D; 9 t FF H), some represent normal

I I characters to be printed, others represent special instructions.The codes from 0 to 31 D are command codes, the codes from 32 D to 255 D are

_ printing characters (numbers, capital letters, punctuation marks, forms,

(I etc.).

Code 27 D (ESC) is a special code and each character immediately following

P| it is also particularly treated. The code ESC n (where n is a character with

! ! a code from 0 to 127 D) is called "ESCAPE SEQUENCE".
