THEORY OF OPERATION

2.4.2 Print Head Carriage Mechanism

This print head carriage mechanism consists mainly of the carriage, carriage motor, gear train, home position
detector, and timing detectors. When the carriage motor rotates, the drive shaft (cylindrical cam) is rotated by the
reduction gear. The print head supported by the carriage moves right and left. The print head position is determined
by timing signals generated by the timing detectors and the home position signal generated by the home position
detector.

Fig. 2-14 Print Head Carrying Mechanism

THEORY OF OPERATION

2.4.4 Ink Ribbon Feed Mechanism

The ink ribbon feed mechanism comprises of the ribbon cartridge, the carriage motor, and the gear train. The gear
train transmits the rotation of the carriage motor to the bevel gear. the ribbon is contained in the ribbon cartridge
and tied into an endless loop. When the bevel gear turns the ribbon feed roller, the ink ribbon sandwiched between the ribbon
feed roller and the ribbon pressure roller is wound up. The ribbon brake spring keeps slack out of the ribbon.

ADJUSTMENT

3.3 Adjusting the Print Speed

The printing speed is critical to ensure maximum reliability of the printer.
If the printing is too fast, the print head cannot keep up and the wires get caught on the ribbon.

1. Remove the printer mechanism according to the procedure described in Section 4.2.

2. Leave the ribbon cartridge installed.

3. To disable the cover open detector, connect Pins 1 and 2 of connector CN4 1 together (for example by putting
a clip between them).

4. Apply the voltages shown below to the pins of printer mechanism connector CN2 2. The carriage motor turns
and the carriage moves left or right.

Pin No. 7 (or No. 8) ....... 24 VDC

Pin No. 9 (or No. 10) ..... Ground

Pin No. 12 ..... 5 VDC

Pin No. 18 ..... Ground

5. The printing speed is calculated from the timing signal frequency.
Connect the measurement terminals of the frequency counter to connector CN2 2 as indicated below and
measure the timing signal frequency.

Pin No. 16 ..... frequency counter input terminal

Pin No. 18 ..... ground

6. If the timing signal frequency is not within the range of 1600 Hz to 1700 Hz (for a sampling period of one second),
use the Phillips screwdriver 3 to turn the knob for the variable resistor 4 on the terminal board and adjust the frequency
of the timing signal.

7. Remove the connector between Pins 1 and 2 of connector CN4 1 and install the printer mechanism on the
main unit by reversing the procedure with which you removed it.
