9.13.2 Troubleshooting

1. When the paper is wrinkled

Adjust the pressure roller screw to set the nip band width close to the upper

limit of the standard value (since the standard value is 6.5 ±0.5 mm, adjust

the pressure roller screw to obtain a nip width of about 7 mm).

Widening the nip width creates an hourglass effect (the nip band is slightly

wider at the ends due to the higher roller pressure). This helps eliminate copy

paper wrinkles.

NOTE: Check that a Mimizu image is not printed on thin paper (see below).

2. Mimizu image

Adjust the pressure roller screw to set the nip band’s width close to the lower

limit of the standard value (since the standard value is 6.5 ±0.5 mm, adjust

the pressure roller screw to obtain the nip width of about 6 mm).

A Mimizu image appears when the paper is strained due to an cessive

hourglass-shape effect. (This is in contrast with the situation where the copy

paper is wrinkled.)

NOTE: Do not narrow the nip width too much. Otherwise, the copy paper

may wrinkle.
