4.2.5.3 Print Head Removal

WARNING
This printer uses left head for dark colors and right
head for light colors, and each head has different
parts code. Therefore, in case of exchanging right
and left heads at the same time, make sure to
follow the points below. Failing to do so gives bad
influence on the printing quality.
„ It is prohibited to use the left head(for dark
colors) as right head(for light colors).
„ It is allowed to use the right head as left head.
„ In case of replacing both right and left heads,
make sure to install each head at proper
position.
1. Remove "Mechanism Unit". (Refer to section 4.2.7)
2. In case of replacing the head, if the carriage is fixed at the home
position, that makes difficult to replace the head. Therefore, it is
necessary to rotate the paper feed roller driven gear(Gear,80), holding
2 protrusions on the gear surface and release the carriage lock. (Refer
to Figure4-18)
WARNING
Do not touch the teeth part of "Gear,80" by your
fingers. Since it is a high precision gear, touching
the gear with bare hands gives bad influence on
paper feeding and printing quality.
3. Release the "Cable, head, left/right" for head control located on the
carriage from the hook.
4. Move the carriage unit to the center of the mechanism, and remove one
CBP screw(3x8) securing "Cover, CR, Rear" over the carriage, and
remove "Cover, CR, Rear". (Refer to Figure4-19)
