Print Results Not Satisfactory When Copying
If these do not resolve the problem, also see “Print Results Not Satisfactory” on page 49.
Printing beyond the recommended
printing area.
If you are printing beyond the recommended printing area of your printing paper,
the lower edge of the paper may become stained with ink.
Resize your original document in your application software.
For details on recommended printing area, refer to “Printing Area” in the User’s
Guide on-screen manual.
Paper Feed Roller is dirty. Clean the Paper Feed Roller. Cleaning the Paper Feed Roller will wear the
roller, so perform this procedure only when necessary.
For details on cleaning, see “Cleaning the Paper Feed Roller (Roller Cleaning)”
on page 41.
Inside of the machine is dirty. When performing duplex printing, if the specified page size does not match the
actual size of paper loaded in the Rear Tray, the inside will become stained with
ink, causing printed paper to become smudged.
Perform the 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 41.
Note
To prevent the inside of the machine from getting stained, set the page size
correctly.
Printing graphics with the intensity
setting set too high.
Especially if you are using plain paper to print images with high intensity, the
paper may absorb too much ink and become wavy, causing paper abrasion.
When printing from your computer, refer to “Print Results Not Satisfactory” in the
User’s Guide on-screen manual.
