•
Alarm bell
Alarm bell sounds to warn the user of mechanical trouble, lack of printing
paper, etc.
•
Bi-directional printing Along with bi -directional printing, there is very effective printing thanks to
the use of logical seeking. (Only 80 characters/line, 40 characters/line)
•
Printing ribbon
io 3
pages in eluding the original, are possible.

IPRECAUTIONS BEFORE SERVICING
• The printer mechanism is fixed to the chassis with two screws to keep it from being
damaged by vibration, etc. during transport. Remove these screws when using, maintaining or repairing the printer.
Fix the mechanism again with these screws when transporting the printer.
Remove the fastening screws
•
•
•
•
•
•
•
Do not apply external force to the print head, such as by touching it when it is
operating.
The print head becomes very hot so do not touch it with your hand until it cools
down sufficiently.
Do not turn the paper feeding knob (manual feed knob) when the power is on or you
will damage the paper feeding mechanism.
Do not print when the ink ribbon is loose.
When servicing and checking a printer that has been used for a long time, remove dirt,
fuzz and dust from th~ inside, and oil the mechanism.
There are two types of oil, G2 and 02. Use the proper oil for each oil point. (Refer
to page 39, 40 for oi I points.)
There are screws and nuts which are fixed and then locked with paint for vibrationproof etc. during transport. Paint the screws to lock them after disassembling and
replacing new parts. (Refer to page 39, 40 for the points to be painted to lock the
screws.)

ADJUSTMENT OF HEAD DRIVING COIL ENERGIZING PULSE WIDTH
This concerns the printing energy force for the head wire to print a dot and its length in time as well. The shorter
the energizing pulse width (time) is, the smaller the printing energy is, thus · weakening printed letters. To the
contrary, the larger pulse width prolongs the printing time of head wire, thereby feeding the head with the head
wire clacking out. In most cases, the head wire is caught by the ink ribbon, and what is worse, the tip of head
wire is broken.
This adjustment is required to give an appropriate printing energy to the head wire. Make an adjustment in the
following manner.
1) Remove cabinet B. (Do not disconnect the connector of feed switch circuit.)
2) Take out the head cord PWB connector from the connector of terminal PWB. Be careful not to damage the
head cord PWB.
3) Turn on the paper end sensor. (Put a piece of paper in the paper sensor lever located at printing paper
insertion area.)
4) Draw out the power supply socket (N0504) with 5-pin lead from the CPU board.
5) Connect 3 units of D.C. power supply to the 5-pin connector (N0504) of CPU board as shown below:
24V D.C. (current capacity: 1.5A or more), 15V D.C. and SV D.C..
6) While pushing the line feed switch of the set, turn on the power switches of the three D.C. power supply
units. (The head is shifted right and left.)
7) Connect the synchroscope to the collector of the transistor 019 (2SC1815) on the drive PWB to check to
see if the pulse width on the synchroscope is 400±1 0 J.J.sec. If the width is out of standard value, rotate the
semi-variable resistor at the drive PWB to adjust the width.
(The semi-variable resistor is to be fixed with lacquer after adjustment.)
Note: Before checking pulse width, calibrate the synchroscope to eliminate error in time base.

•
Sensing Mechanisms
Sensing mechanisms consist of HP sensor, PTS sensor and PE sensor. The HP sensor is attached to determine the
Home Position of the carriage and generates the reference signal for printing.
The PTS sensor generates the timing signal used to determine printing position. lt detects this signal and adjusts
carriage speed. The PE sensor detects the presence or absence of paper.
1.
HP Sensor (Home Position Sensor)
The HP sensor consists of the home position sensor assembly and sensor board on the lower part of the carriage.
The signal is High when the sensor board interrupts the light shaft of the photo coupler . .lt is an open collector
output)
-20-
2. PTS Sensor (Print Timing Signal Sensor)
The PTS sensor consists of the PTS sensor board assembly and the sensor board on the timing belt motor shaft.
The signal is Low when the slit of the sensor board appears. (lt is an open collector output.)
3. Paper Sensor
The paper sensor consists of the reed switch attached to paper sensor board and the permanent magnet attached
to the paper sensor lever. The permanent magnet approaches the reed switch and the signal passes when there is
no paper.

• Printing Mechanism
The main elements of the printing mechanism are print head unit, carriage, timing belt, timing belt motor and
platen. The print head unit on the carriage is moved to the right and left by the timing belt on shafts A and B of the
carriage guide. The timing belt is driven by the timing belt motor through the belt driving pulley and belt driving
pulley.
Printing performs when the dot wire springs out toward the platen due to the flow of c1,.1rrent in the head driving
coil. The current flows when the PTS signal is generated by the belt motor rotation.

2. Printing function of the Print Head
This explanation is for the wire movement of one dot when one character is formed.
1) The function plate is pulled in to the core when current flows in the driving coil and thus the dot wire springs
toward the platen since it is connected with the function plate.
2) The forced dot wire springs out till it strikes the platen and one dot is printed on the paper through the ribbon
when it strikes the platen.
3) The function plate is reset to its former position by the force of the function plate spring when current no
longer passes through the driving coil.
The dot wire, after it strikes the platen, returnes to its position, which is connected with function plate, by its
striking force and the wire return spring and maintains itself in a waiting condition.

Paper Feeding Mechanism
The paper feeding mechanism has ordinary feed, fast feed. Paper is fed by the sprocket shaft using the sprocket
transmission gear driven by the paper feeding motor and the sprocket driving gear. Paper is fed by pulling the paper
up with the sprocket pins. The drive method for the paper feeding motor is the same as the carriage motor rnoves
the carriage from right to left.
The printing position on the paper can be adjusted with a knob, but the adjustable minimum width is about 0.5mm
because of the resolution precision of the pulse motor .

Ribbon Feeding Mechanism
The ribbon mechanism consists of the cartridge ribbon and ribbon feeding mechanism. The ribbon feeding mechanism is attached to the belt tension plate assembly. Movement of the timing belt to the right and left is through
the following arrangement of wheels. The ribbon driving gear normally turns counterclockwise.

The ink ribbon is stored endlessly in the cartridge case. This ink ribbon, pinched between the ribbon feeding knob
and ribbon pressure roller, is wound UJ3 by the ribbon feeding knob set on the ribbon driving gear.
Furthermore, there is a ribbon braking spring at the outlet of the cartridge case to. prevent the ribbon from becoming
loose as it is wound. A ribbon mask is attached to prevent the paper from becoming dirty.
