Check description
1. Check if the cutting
edge of the paper
bundle is crumpled or
the cassette is loaded
with multiple times of
replenishing paper.
2. Checking paper size.
Check that the size of
the loaded paper and
the paper size chosen
on the operator panel
are met.
3. Check if paper dusts
and abrasion are
observed on the paper
fanning roller and retard
roller.
4. Select the motor by
U032 and check the
clutch rotates following
the other component
when the motor is
turned on. (see page 1-

Perform U031 to check if
the regist sensor is

Corrective measures
If the cutting edge of the paper bundle is crumpled or
the cassette is loaded with multiple times of
replenishing paper, load new paper.
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 paper size detector
switch is turned on.
If the size is not detectable while automatic sizing
is enabled, replace the size detection switch.
If the paper size agrees
1. If paper other than complying the requirements
such as coated paper, inkjet paper, etc., is used,
replace the paper.
2. RE-assemble the retard roller in the primary
paper feed 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.
If the paper fanning roller is dirty, clean.
If abrasion is observed, replace.
If the clutch rotates following the other component
and its stain is observed, replace the clutch.
If the regist sensor is not working, replace the regist
sensor.
