1.2.3. Gloss line caused by fusing paper exit roller

(1) Symptom
When printing the high coverage original, gloss line may occur on image.
(2) Cause
When paper passes through the fusing unit, the fusing paper exit roller and the paper surface
contact each other, which lowers the temperature of contacting area. The difference of gloss
level between contacting area and non-contacting area causes gloss lines.

1. Change pressure of the fusing paper exit roller
Change pressure of the fusing paper exit roller to release position.
Note
• Be sure to align the knob with the mark. Do not set to unmarked position.
• When releasing the fusing paper exit roller, if the length of conveyance direction (FD) is
shorter than A4, paper cannot feed. However, 4 imposing postal card can feed.
2. Change of fusing temperature

follows.

[Paper Setting]→[Change Set]→[Expert Adj]→[Upper Fusing Roller Temperature]
When changing the temperature, reduce by 10°C for the first step. If not enough, gradually
decrease (maximum by 20°C). Print 20 sets of test pattern No. 69, and confirm that fusing
under does not occur.
