1st document
(1) Paper feed 1 for the second document
If the ADF document sensor is photointerrupted
when the document has been ejected and
master making process is finished at the
master feeding section, it is determined that
the next document exists and the ADF stepping
motor, and the ADF clutch A is turned on to
feed the document.
(2) Positioning
When the front end of the document reaches
the ADF document lead edge sensor, the ADF
document lead edge sensor is photointerrupted
and detects the front end of the document,
which turns off the ADF stepping motor and
the ADF clutch A to hold. This method assures
stable positioning of the document.
(3) Reading the document
After the front end of the document is detected
at the ADF document lead edge sensor, the
document is fed several steps, and shading is
performed on approximately 2 mm of the front
end of the document.
IMPORTANT
● When the previous document has been
printed, the printer detaches the master
and then the drum moves to the master
attachment position to open the master
clamp. During these operations, the ADF is
in the standby status.
