6.1.13 Engine Unit and Flushing Box
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 replace all
four ink cartridges with the protective part (see page 6-3).
(1) If the MJ/PS shield unit has not been removed, you need to remove screw "f" shown on
page 6-39.
(2) Remove the screw from the rear of the engine unit.
(3) Take the carriage motor harness, ASF motor harness, purge cam switch harness, and cap
lift cam switch harness out of the harness guides provided on the lower cover.
Assembling Note: If you replace the engine unit, make adjustments specified in Chapter 7,
Section 7.2.
Assembling Note: When routing the cap lift cam switch harness, first check that it passes
through the cable guide on the maintenance unit and then pass it under
the 2nd cable guide (on
the lower cover) counted from the rear, pulling it with your fingers as shown above.
After routing the harness, make sure that there is no slack in the harness. If slacked, the harness
interferes with the planet gear on the maintenance unit, causing MACHINE ERROR 50.
