Head/Carriage Unit

During disassembly jobs, except when removing the ink refill ASSY or engine unit (including
the maintenance unit), leave the head/carriage unit in the machine.
Before removing the head/carriage unit, ink refill ASSY or engine unit, you need to remove all
four ink cartridges and set the protective part instead (see
protective part into place to prevent ink remaining in the ink supply tubes from leaking and the
machine from getting stained with leaked ink. (Check that the right-hand latch fits in the hole
provided in the ink refill ASSY.)
Note: When replacing the head/carriage unit, put on a grounding wrist band and perform the job
on a static mat. Also take care not to touch the conductor sections on the flat cables.
Note: During the removal or installation job for the head/carriage unit, take care not to
contaminate the CR encoder strip or PF encoder disc with ink or grease.
Note: If you replace the head/carriage unit, also replace the ink cartridges. This is because
sufficient ink volume is necessary for refilling the ink supply tubes after replacement of the
head/carriage unit.
