Connect the power cord, turn the main switch ON, and
perform the following procedure.
13) Check the magnification ratio.
Place a document on the document glass and make a copy.
Then, place a document in the automatic document feeder tray and
make a copy.
∗If the copy magnification ratio of the copy made with the automatic
document feeder is different than that of the copy image made with
the document glass, perform the magnification adjustment accord-
ing to the procedure in the service manual.
14) Check the center displacement.
Place a document on the document glass and make a copy.
Then, place a document in the automatic document feeder tray and
make a copy.
∗If the center of the copy from the automatic document feeder is
displaced from the copy from the document glass, adjust the cen-
ter according to the procedure in the service manual.
15) Check the leading edge margin.
Place a document on the document glass and make a copy.
Then, place a document in the automatic document feeder tray and

2. Brief descriptions of operations
3. Document size detection
Document size detection by document set tray
When a document is set on the document set tray in the auto mode of
paper/copy magnification ratio selection, the document size is
detected to perform the auto selection function of paper and the copy
magnification ratio according to the detected document size.
When documents of different sizes are mixed and set on the tray, the
max. size is detected. The document width is detected by the docu-
ment width sensors (W1, W2, W3), and the document length is
detected by the document length sensors (L1, L2) to determine the
document size.
The document size judgment is made after a certain time from when
the document set sensor (W0) detects the document.
