Registration Roller Up/Down Mechanism
After the printing paper is caught between the drum and the press roller, the upper
registration roller is released from the lower registration roller. This is to prevent
interference from the registration rollers while the paper is transported by the drum
and the press roller.
When the high point of the cam [A] on the drum drive gear reaches the cam
follower [B], the shaft [C] rotates clockwise (as seen from the operation side) to
raise the upper registration roller [D] from the lower registration roller (not shown).
