Reassembling Notes
• Route the ink tubes and head flat cables of the needle tube & head flat cable ASSY on the engine
lower frame as shown on the previous page. For routing them on the ink cartridge support base,
refer to "Routing F" in Section 6.1.15 "Routing of the Harnesses and Flat Cables."
• Pass the CR encoder strip through the CR encoder sensor located at the back of the carriage so
that the
V
-
marked end is to the left and the
V
mark points upwards, as shown on page 6-37.
Hook the
V
-marked end on the left end of the engine lower frame. Next, hook the right end of
the encoder strip on the encoder strip spring and secure the spring to the right end of the engine
lower frame with screw "r."
• When setting the purge unit back onto the engine unit, keep the head wiper and cap cam in the
most retracted position. If the wiper protrudes, turn gear 4 clockwise to retract it. If you set the
purge unit with the wiper protruding, the top edge of the wiper may be bent by the bottom of the
engine unit. After turning the machine to the normal position, pull up the top edge of the wiper
with tweezers or similar, taking care not to damage it.

disk surface from dust or fingerprints.
• When installing the engine unit, temporarily tighten six screws ("g" and "h," as shown on page 6-

then tighten the same six screws (four "g" screws first and then two "h" screws) firmly.
• If the old Ink Absorber Case(LF0573001) is attached to the set when the purge unit is replaced,
please replace for the new Ink Absorber Case(LF0927001).
