When the PRNT* signal arrives from the printer board*
becomes ready, the DC controller PCB starts printing operation.
In the case of pick-up from the cassette, paper is fed into the printer unit by the pick-
up roller and is moved by the feeding roller; in the case of pick-up from the multifeeder,
on the other hand, the multifeeder pick-up roller feeds paper into the printer unit.
The orientation of the paper is corrected by the registration roller so that it will not
move askew; the paper is then stopped and kept in wait. Then, the paper is started once
again so that its leading edge and the leading edge of the image on the intermediate
transfer drum will match; the paper is further moved through the transfer, separation, and
fixing/delivery assemblies all the way to the face-down tray or the face-up tray.
