4- 4. Reassembly
Reassembly of parts is performed by reversing the disassembly procedure.
Note the following points :
(1) Properly lubricate all parts that require lubrication.
(2) Bundle harnesses firmly and accurately enough to avoid interference with gears
(3) Lastly install the Platen Gear B as follows (See the drawing):
• Match the Cam Gear and the hole of the Base Plate Ass'y.
• Place the hole of the Platen Gear B facing straight upward. As it comes into the upright position, it will emit a
clicking sound. At this time, the Platen Ass'y is at the lowered position.
(4) Check the following sliding parts :
1. Gears
2. Cam and Cam B
3. Carrier Ass'y
4. Platen Cover and Sensor Block
5. Sensor Block and Sensor Lever
6. Platen Block
(5) Check clearances in the following parts :
1. Cam and Cam B (right and left)
2. Carrier Ass'y (rack engagement)
3. Platen Plate
(6) Check for backlash between gears.
(7) Attach spring parts firmly at their right places to ensure the spring works properly.
*Attach the Carrier Spring so that their faces contact the Guide Shaft.
(8) Attach two sensors of the Sensor Harness B Unit firmly at their right places
*The one with a longer harness is the home position sensor, while the one with a shorter
harness is the encoder sensor.
(9) When attaching hook-shaped parts, be sure that the hook parts are firmly attached.
(10) Direct the Cam C in the proper direction when installing it.
(11) When installing the FPC of the Print Head on the Base Plate Ass'y, check to see if the installation length of the
FPC is appropriate or not by moving the Carrier laterally.
(12) When assembling the harness of Switch PCB Ass'y to the Platen Cover, be sure that the Sensor Block operates
to the proper range.
