CHAPTER 2 BASIC OPERATION
Reference:
At time of a jam, the copier remembers how may originals it has copied, and sends the
information to the ADF controller upon removal of the jam.
In response, the ADF controller circulates the originals that have been copied already, and
places the originals that have not been copied on the copyboard for copying. For this reason,
normal copying operation would not be possible if the number of originals after removal of
jams differs from the number of originals before the jam.
In the case of [1] in the following diagram, the ADF and the copier will stop to operate, treating
the condition as a “different numbers of originals.” Keep in mind, however that, in the case of
[2], normal operation will continue.
1. Resetting
To reset in response to wrong placement of originals, remove all originals from the original tray,
and place them back again. The copier will indicate a message; follow the instructions.
10 originals are placed
on the original tray.
The 8th
original jams.
The originals are put
back into order, and
placed on the original
tray (10 originals).
The first 7 originals (which
have been copied) are count-
ed, and copying starts with
the 8th original.
The 3rd
original jams.
8 originals are placed
on the original tray.
3 originals are set
on the original tray.
The number of operations
are counted, and the ADF
is stopped.
Error [2]
(7 originals have been
copied)
Error [1]
Nor
mal
(2 originals have been
copied.)
10 (originals) - 2 (originals that have been copied) = 8 originals
10 (originals) - 7 (originals that have been copied) = 3 originals
The originals are counted,
and then copying starts with
the 2nd original.
