3.9.2 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 the previous page). 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. (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 disk with ink or grease.
(1) Plug the power cord into an electrical outlet.
(2) Open the scanner cover (scanner unit) until it locks.
The "Cover is Open." message appears on the LCD.
(3) Hold down the Stop/Exit key to move the head/carriage unit to the center of its travel.
