PAPER FEED 1 July, 1998
2-60
Registration Roller Up/Down Mechanism
After the paper is caught between the drum and the pressure cylinder, the upper
registration roller is released from the lower registration roller. This is to prevent
interference from the registration rollers while the paper is being fed by the drum
and the pressure cylinder.
When the high point of the cam [A] on the drum drive gear reaches the cam
follower [B] (a bearing), the shaft [C] rotates clockwise (as seen from the operation
side) to release the upper registration roller [D] from the lower registration roller.
