Image Quality Troubleshooting

When an image problem occurs, exchange the Toner Cartridge and/or Drum Cartridge for a new one
and determine whether the cause of the problem is due to one of the cartridges or something else in
the printer.
If an image quality problem occurs with the printer, first replace the Toner Cartridge or Drum Car-
tridge.
If the problem still occurs, please use the following chart to help determine the defective unit.
