5. Releasing the Registration Roller
The registration roller is released so as to make up for the minute discrepancy between the speed at
which paper is moved by the registration roller and the speed at which it is moved by the transfer belt so as
to prevent displacement of the image, which could occur otherwise.
In the case of pick-up from the multifeeder, the registration roller starts to rotate; and, when the paper
has moved on the transfer belt, the registration roller releasing solenoid (SL16) turns on.
As a result, the drive of the pick-up motor is transmitted to the registration releasing arm by way of the
spring clutch and the registration releasing cam, causing the registration roller (upper) to move up and
releasing its pressure. (The registration releasing cam makes a 1/2 rotation when the registration releasing
solenoid turns on by the work of the spring clutch.)
The solenoid SL16 is on in the presence of a jam.
