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
NOTEthe power is turned ON, when documents are inserted and when documents are ejected.
Document feed lever
Switching between automatic document feed and manual document feed is carried
out by the document feed lever above the left side of the LCD. During automatic
document feed, documents are gripped between the separation guide and the sepa-
ration roller. Switching the lever to manual document feed raises the separation
guide and frees it from the document. Manual document feed can therefore mini-
mize the possibility of damage caused by pinching between the separation guide
and separation roller when feeding documents such as thick-stock paper or photo-
graphs. However, because document separation does not occur in manual docu-
ment feed mode, only one sheet at a time may be loaded. Loading multiple sheets
will result in double feed.
Document Jam Detection
There are two types of document jams which may occur:
a) Feed jam
Occurs when the document edge sensor cannot detect the document's leading edge within
15 seconds after the start of document separation.
b) Eject jam/document too long
Occurs when the document edge sensor cannot detect the document's trailing edge within
one meter of feeding after the document's leading edge is detected.
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.
