Paper size detection
The paper size is automatically detected by the
following three sensors:
• Lateral: Paper size detection VR (VR4)
• Longitudinal: Paper size PS 1/2 (PS55/PS56)
[3] First Paper Feed Control
The 1st paper feed from the by-pass tray takes place
as the result of the transmission of the drive force from
M6 (loop roller) to the paper feed roller. SD11 (pick
up (by-pass tray)) moves up and releases the paper
feed roller contacting to the paper after the roller picked
up and fed the first paper to the feed roller side to
facilitate paper feeding.
The above operations are controlled by the PRCB
(printer control board).
