Skewed paper

- Paper feeding from
the cassette, Photo
Paper Plus Double
Sided, 5 x 7 size
Due to its
mechanism,
contact of the PF
pinch rollers to the
5 x 7 size paper is
uneven, which is
likely to cause
skewed paper
feeding.

feeding method
from the cassette to
the auto sheet
feeder.

2 B Paper feed
Improper paper
feeding:
- Multi-feeding
- Skewed paper
feeding
- Paper jam
- Paper feeding from
the ASF
- Plain paper
- Highest print speed
(Custom setting to
5)
- In the high
temperature and
high humidity
environment
- In the low
temperature and
low humidity
environment
- With the maximum
amount of paper
set (13 mm)
In the high
temperature and
high humidity
environment, paper
becomes wavy; in
the low
temperature and
low humidity
environment, paper
curls significantly.
When the
maximum amount
of paper is set in
the ASF, and if the
paper-return tab
fits in a wave or
curl of the paper,
the tab slips and
does not catch
paper properly,
causing paper feed
problems.
- Reduce the
amount of paper
set in the ASF to
half (approx. 5
mm high).
- Multiple
sheets of
paper feed at
the same
time.
- Paper feeds at
an angle.
- A paper jam
occurs.

- Paper feeding from

- Credit Card size
Since coaxial
tolerance between
the pinch roller and
the LF roller,
which determines
the paper feed
alignment, is
0.2mm, skewed
paper feeding can
occur. However,
according to the
field data of current
models, the
skewness level
caused by the
coaxial tolerance of
0.2mm is within
the criteria of +/-
1%, thus the
phenomenon is left
as is.
