c Sheet conveyance
When the sheet fed from the paper
feed unit at low speed turns
PS201/PS206 (PI passage /U/L) on,
M203 (PI conveyance) changes its
rotating speed to high-speed. At this
time, as MC203 (registration) turns
off, the sheet is pressed against the
conveyance rollers /U/L to form a
loop. MC203 turns on when a
specified time has passed since
PS201/PS206 turned on, and the
drive force of M203 is transmitted to
the conveyance rollers /U/L. This
causes the sheet whose bend is
corrected by loop formation to be
conveyed into finisher.
When the sheet turns PS206 off,
MC203 turns off after a specified
time. With the same timing, MC203
changes its rotating speed to
low-speed and comes into feeding
operation for the next sheet.
d Detection of sheet size
VR201/VR202 (sheet size/U/L) detect
the sheet width.
Sheet length is detected by the
combination of PS203/PS208 (sheet
setting/U/L) and PS212 (sheet
size/L).
