6-56 Confidential
Assembling Notes
• Before mounting the engine unit on the lower cover, make sure that the PF encoder/registration
sensor harness and the paper feed motor harness are routed through the cable guides on the inner
chute as shown on page 6-60.
• When mounting the engine unit on the lower cover, be careful not to crush the harnesses between
the unit and the cover. Mount the engine unit parallel to the lower cover so that the screws are
tightened securely.
• Route the harnesses as shown below.
