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.

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, and then see the corresponding

reference pages to troubleshoot the problem.

Note The following examples depict letter-size paper that has passed through the MFP long-edge first.

(If the paper has passed through the MFP short-edge first, lines and repeating defects will run

vertically rather than horizontally.)
