6.1.11 Head/Carriage Unit and Ink Refill ASSY
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 page 6-3). Be sure to insert the protective part
into place to prevent ink remaining in the ink supply tubes from leaking and the machine from
getting stained with leaked ink.
NOTE: Make sure that the power cord is unplugged from the electrical outlet.
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 disk 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.
