Correcting output quality problems
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.)
