Registration Roller Up/Down Mechanism
[D]
• After the printing paper is caught between the drum and the press roller, the
registration motor stops and the upper registration roller [A] is released from the
lower registration roller. This is to prevent interference from the registration
rollers while the drum and press roller transport the paper.
• When the high point of the cam [B] on the drum drive gear reaches the cam
follower [C], the shaft [D] rotates clockwise (as seen from the operation side) to
release the upper registration roller [A] from the lower registration roller.
