Supplement:
Example
10 originals are placed
on the original tray.
When a jam occurs, the copier knows how many documents have been copied.
When the jam has been removed, the copier sends the data to the RDF. The
RDF, in response, circulates the copied documents, and positions the remain-
ing documents on the platen for copying.
For this reason, normal copying will not continue if there is a discrepancy in
the number of documents counted: before and after a jam has occurred.
For error 1: the RDF will stop, and the display will be 'different number of doc-
uments after jam removal'.
For error 2: the RDF will continue to function.
Resetting
To reset the machine after it has stopped because of the incorrect positioning
of documents:
- remove all documents from the document tray.
If a message is displayed, follow the instructions accordingly.
However, if the machine is stopped during image composition mode
- open the machine after removing the documents from the document tray.
ed.1
The 8th original
jams.
(7 originals copied)
The 3rd original
jams.
(2 originals copied)
The originals are put
back in order, i.e., 10
originals are set.
3 originals are set on
the original tray.
10 (originals) - 7 (copied) = 3 originals
8 originals are set on
the original tray.
10 (originals) - 2 (copied) = 8 originals
After counting the 7 originals
that have been copied,
copying resumes starting
with the 8th original.
The RDF stops operation
after counting the
originals.
After counting the originals,
copying resumes starting
with the 2nd original.
