Correcting output quality problems Note 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. 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.)
