Correcting output quality problems

The first step in correcting output quality problems is to determine if the image defect is present when copying and printing, or only when copying. If the image defect is present only when copying, see “Cleaning the ADF delivery system” on page 84 or “Cleaning the scanner glass” on page 89.

If the image defect is present only when printing, use the examples in the image defect table to determine which print quality problem you are experiencing, then see the corresponding reference pages to troubleshoot.

Note

The examples below depict letter-size paper that has passed through the product long-edge first. (If the paper has

 

passed through the product short-edge first, lines and repeating defects will run vertically rather than horizontally.)
