- 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 or automatically with the FORM FEED key)
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
This chapters contains two flow charts designed to help less expert
technicians to trace printer faults. 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
or is due to the local mains system.
If mains power is present, refer to the flow chart of page 5-2. 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 a
local test on it.
The printer can not perform a local-test or the Set-up procedure if the Computer connected by the serial interface (C64/128) is OFF.
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
the printer (interface, printer emulation, open mode, character set, ecc.).

8. 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 - 6.5 mm from the platen (2).
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
8-1
Page 56
MPS 1230 SERVICE MANUAL
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.
8-2
Page 57
MPS 1230 SERVICE MANUAL
8.3 ADJUSTMENT OF THE PAPER DETECTOR PHOTOSENSOR
When you change the board, or you change the EPROM firmware with a new
release, you must perform the paper detector adjustment. In order to perform this adjustment follow this procedure:
A. Press LOCAL and LINE FEED keys and turn on the printer without releasing
them for about 10 sec. This operation must carried out without paper in the printer. The LOCAL led will blink now.
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 EEPROM.
If the platen do not the revolution described on point B, switch OFF the printer and cut the R1 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 R1 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
resistor concerned.

Signal Description
The DATA STROBE signal is a negative pulse that transfers data into the printer electronic circuits. The pulse duration must be longer than 800 ns. The 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 transferred must be stable at least 800 nsec before the negative edge of the "strobe" impulse and must remain stable at least 800 nsec after the positive edge of the "strobe". These signals are pulled up with a 1 kohm resistance
towards the +5 Volts.
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 10 msec.
The ACKNOWLEDGE signal is a negative impulse which is used by the printer to
indicate complete transfer of the character and that the next character can
therefore be sent.
The 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.
The SELECT signal is active when high and indicates that the printer has
been selected and is ready for "data transfer".
The FAULT signal is active when low and indicates to the C.U. that the printer is faulty.

MPS 1230 SERVICE MANUAL
E. COMMAND CODES
Instructions for printing are sent to the printer in the form of bytes, i.e. groups of eight bits, transferred simultaneously through the cable connection.
The coding system used is called ASCII and is based on the relationship between bits and characters (for example, the letter A correspond to the byte 01009001). The equivalent code for each character is given in the appendix F. To avoid always writing the full sequence of eight bits, decimal equivalents will be used; the number precedes the letter D, (A = 65 D), or
the hexadecimal code - the number precedes the letter H (A = 41 H). Of the 256 codes available (0 t 155 D; 0 t FF H), some represent normal
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, etc.).
Code 27 D (ESC) is a special code and each character immediately following
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".
The codes are described in the User Manual.
