The following diagram shows the possible symptoms (black or white dots at regular intervals).
• Abnormal image at 24-mm intervals: Image transfer belt unit
• Colored spots at 38-mm intervals: AIO cartridge (Development roller)

• Abnormal image at 141.3-mm intervals: Fusing unit (Fusing belt)

Checking a Sample Printout

Print out a mono-color pattern (all K, C, M, or Y), which will clarify if the cause is a problem with one of
the AIO cartridges, Image transfer belt, image transfer roller, or the fusing unit. A sample page is
provided with the printer driver's CD. You can print the sample page from the printer driver's CD. Before
printing, you have to adjust the printer driver settings to make the problem become obvious. For details
about adjusting the settings, refer to "Printer Driver Setting for Printing a Sample" described below.
• Occurs with 1-3 colors: AIO cartridge(s) failure
• Occurs with all four colors: Image transfer belt, transfer roller or fusing unit failure
