„Printed Surface Is Scratched/Paper Is Smudged

Cause

Action

Paper Feed Rollers are dirty.

If paper is not feeding properly, clean the Paper Feed Rollers. Cleaning the

 

Paper Feed Rollers of the Auto Sheet Feeder will wear the rollers, so perform

 

this procedure only when necessary.

 

For details on cleaning, see “Cleaning the Paper Feed Rollers (Roller Cleaning)”

 

on page 53.

Inside of the machine is dirty.

Performing duplex printing may leave some ink inside the machine, causing

 

printouts to be smudged. In this case, perform bottom plate cleaning to clean

 

the inside of the machine.

 

For details on cleaning, see “Cleaning the Inside of the Machine (Bottom Plate

 

Cleaning)” on page 54.
