Details of control
When you copy or print more than 100 sheets of narrow paper and then copy or print wide paper,
a thin glossy line sometimes appears in parallel with the feeding direction with the same width as
the paper used previously. (For example, when you use A3 paper after using A4R paper) (For US,
when you use 12x18 size paper after using 11x17 size paper)
In this case, you may be able to minimize the glossy line by refreshing the fixing roller.
