NOTE: 1) The CPU controls the registration roller start timing to synchronize the
printer paper with the image on the master on the drum.
2) The motor speed depends on the selected printing speed.
3) By pressing the image position keys on the operation panel, the
registration motor start timing is changed.
Registration Roller Up/Down Mechanism
• After the printing paper is caught between the drum and the press roller, the
registration motor stops and the upper registration roller [D] 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 [E] on the drum drive gear reaches the cam
follower [F], the shaft [G] rotates clockwise (as seen from the operation side) to
release the upper registration roller [D] from the lower registration roller.
