NOTE
Initializing the upper document feed roller
When the separation roller starts to rotate, the position of the upper document feed roller is
simultaneously initialized to raise the document stopper. Initialization is carried out when
the power is turned ON, when documents are inserted and when documents are ejected.
Document Jam Detection
There are two types of document jams which may occur:
a) Feed jam
If the document edge sensor (DES) does not detect the leading edge of the original within
15 sec after the original is started, the condition will be identified as a pickup jam error
and the movement of the original will be stopped.
b) Eject jam/document too long
If the trailing edge of the original cannot be detected within a period of time equivalent to
1 m after the document edge sensor has detected the leading edge of an original, the
condition will be identified as an original delivery jam/original excess length error, and
the movement of the original will be stopped.
When one of these types of jams occurs, all data which have been read and stored in memory
(except pages that have already been completely transmitted or copied) are erased.
