102 MFP unit explanation ENWW
a high speed, M6 (loop roller) is turned
off to form a paper loop in the
registration section.
b Second paper feed control
After formation of a paper loop under
loop control, MC1 (registration) is turned
on to transmit the drive force of M5
(conveyance) to the second pick roller,
starting the second paper feed.
c Image position correction control
Mis-centering of the paper fed from
each tray is detected by PS70 (paper
mis-centering) and the paper leading
edge timing is detected by PS43
(leading edge) and they are corrected at
the time of image write.
A contact image sensor is used as
PS70 (paper mis-centering). The paper
edge position is detected by paper
mis-centering sensors. Based on the
edge position information, the image
write position is shifted to correct
mis-centering and leading edge timing
at the time of image write. PS70
operates after a lapse of the specified
time from turning on of PS43 (leading
edge).
