Is the original placed correctly?
Is the paper loaded correctly?
The paper must not exceed
the maximum number of
sheets and must not be
higher than the indicator line.
If the original is stapled, be sure to remove the staples and
fan the pages well before placing. (This is to prevent
misfeeding and tearing of the original, and to prevent torn
fragments of the original from remaining in the feeder.)
Align the edges and place
face up
Check if the size of the original you placed matches the
original size shown on the touch panel.
When loading A4 size paper in tray
1, or 8-1/2" x 14" paper in trays 2

paper feed opening (right side),
and pull up.
If the machine does not recognize
the paper size even though A4
size is correctly loaded in tray 1, or
8-1/2" x 14" size is correctly
loaded in trays 2 to 4, check if the
holder in the cassette is positioned
at A4 (8-1/2" x 14" in trays 2 to 4).
When setting 8-1/2" x 11" size
paper in tray 2 to 4, remove the 2
