6 ADF overview ENWW
Original conveyance process
The ADF consists of an original feed section, conveyance section, reversal section, and original
exit section.
The original face up on the original feed tray,
is fed from the topmost original. The fed
original is not conveyed to the original glass.
Instead, it is read when it passes the ADF
glass placed in the conveyance path.
The ADF operation consists of single side
original copy mode, double side original
copy mode, mixed original copy mode and
Z-fold mode. Each has a different
conveyance path.
Single side original copy mode
(single side to single side, single side to
double side)
The original set in the original feed tray is
pressed to the pick roller by the original
pressing board. The pick roller and feed
roller pre-feed the original until the original
registration PS/1 (PS304) turns on and
original reaches the registration roller.
After completing the registration loop, the
registration roller re-feeds the original and
the original is conveyed to the read section.
The original is conveyed by the conveyance
roller. The scanning starts when the original
registration PS (PS306) turns on.
