Part 2 : Troubleshooting
3.3.4

Installing and removing the carriage encoder film

The carriage encoder film is fixed in place by the leaf spring. When installing or removing
the carriage encoder film, be careful not to distort the leaf spring.
3.3.5

Handling the encoder film

Be careful not to contaminate or get any grease on the encoder film (carriage/LF). If grease
gets on the encoder film, the film's slit will not be read correctly, resulting in error. If grease
gets on the film, use alcohol to wipe it off completely.
Also, do not fold or scratch the encoder film.
3.3.6

Installing and removing the carriage unit

When removing the carriage unit, remove 3 carriage ribbon cables and the carriage belt.
The carriage belt is hung on the idle pulley and the carriage motor. If the idle pulley is
pressed inward, the belt will come off. When installing the carriage belt, press the idle
pulley inward and hang it to the motor and the pulley. It is not necessary to adjust the
tension.
3.3.7

Removal of red screws prohibited

As it is quite difficult to adjust red screws of the print unit in the field, they must not be
loosened or removed.
3.3.8

Installing and removing the ink supply unit

When removing the ink supply unit, ink tanks have to be removed first. Also, detach the ink
supply tubes from the carriage joint part. As the ink absorber is placed underneath the ink
supply tank and ink might be attached there, when it is put down, avoid contamination by
placing sheet underneath.
3.3.9

Installing and removing the carriage motor

When replacing the carriage motor, remove the carriage belt and pull out the motor from the
top by rotating it.
3.3.10 Installing and removing the print head
The print head has to be installed or removed at the certain position.
Replace the head at the position where the joint part of ink tubes can be pulled forward.
When removing the head in use, ink drain must be performed first. It is necessary to drain
ink inside the tubes and the head. Also, even if ink is drained, a little amount of ink may
remain inside the head. Be careful for ink leakage when carrying the print head.
