Releasing The Registration Roller - Canon CLC5000 Service Manual

CHAPTER 2 NEW FUNCTIONS

5.4.3 Releasing the Registration Roller

The registration roller is released to make up for the minute discrepancy in speed between
the registration roller and the transfer belt occurring when thick paper is moved, thereby
preventing displacement of images during transfer.
When the multifeeder is the source of paper, the registration roller releasing solenoid
(SL16) turns on as the registration roller starts to rotate and the paper is attracted to the
transfer belt. This causes the drive of the registration motor to be transmitted to the registra-
tion releasing arm by way of the spring clutch and the registration releasing cam, moving up
the registration roller (upper) and releasing the registration roller as shown in the following
figure (the registration releasing cam is turned halfway by the work of the spring clutch
when the registration roller releasing solenoid turns on).
The registration releasing solenoid (SL16) is also on in the presence of a jam.
