Gloss lines on image due to the scratches on the surface of fixing
roller which the refresh roller gives in its operation
[Symptom]
When installing the product or when feeding the coated paper during the initial period ( feeding approx. 30,000 sheets) after the
refresh roller replacement, thin gloss lines in the paper feed direction might occur on a main body whose serial number is earlier
than the following countermeasure cut-in serial numbers in factory.
[Note] Gloss lines are remarkable especially with coated paper.
[Cause]
The refresh roller presses onto the fixing roller and scrapes the surface layer of the fixing roller under the specified conditions in
order to remove the streaky scratches appears on the fixing roller in a large quantity of printout.
However, as the surface of a new refresh roller is somewhat rough, the refresh roller might give fine scratches to the fixing roller
in its operation and this result in the above mentioned symptom.
[Service work]
When the aforementioned symptom has occurred, prepare and replace with the new type refresh roller (FM1-T299-000) referring
to the service manual.
