Roller trace on transparency
[Location]
First Delivery Roller
[Cause]
As the number of fed sheets is increased, the First Delivery Roller is soiled. With the normal
paper, any problem does not occur, but when transparency is used, its soil may be adhered
on the roller.
[Condition]
This failure occurs when the number of fed sheets is increased, the First Delivery Roller is
soiled, and transparency is fed.
[Field Remedy]
Change to the Delivery Tray other than First Delivery Tray. Clean the First Delivery Roller with
lint-free paper moistened with alcohol.
