loaded with multiple times
of replenishing paper.
If the cutting edge of the paper bundle is crumpled or the cassette
is loaded with multiple times of replenishing paper, load new
paper.
2 Checking paper size.
Check that the size of the
loaded paper and the paper
size chosen on the operator
panel are met.
If the paper size does not agree.
1 If the cassette cursors are open against the paper, set it
properly.
2 Insert the cassette until the cassette size detector
switch is turned on.
If the size is not detectable while automatic sizing is
enabled, replace the size detection switch.

coated paper, inkjet paper, etc., is used, replace the
paper.

unit if it is mounted to the oppisite direction.
3 Check if the retard spring has not been fallen off of the
mounting position.
• If the retard spring is not dropped off of the mount
position, decrease the spring pressure that is applied to
the separation rollers.
4 Replace the primary paper feed unit.

abrasion are observed on
the paper fanning roller and
retard roller.
If the paper fanning roller is dirty, clean.
