Solution
• If the Toner Low light is on, remove the print cartridge. To
utilize the remaining toner, shake the print cartridge gently,
and then reinstall it. See
cartridge for an illustration of how to shake the print
cartridge.
• Change the Toner Darkness setting to a value greater than 8
in the Local Printer Setup Utility.
• If you are printing on transparencies, card stock, or labels, be
sure you selected the correct Paper Type in the printer driver
or in the Local Printer Setup Utility.
Note: For more information, see
Utility.
• If you are printing on an uneven print surface, adjust the
Paper Weight and Paper Texture settings.
• Use recommended paper and other print media. Refer to the
Card Stock & Label Guide available on the Lexmark Web site
at www.lexmark.com for detailed specifications.
• The printer detects a print cartridge error. Replace it.
• Make sure print media you load in the sources is not damp.
• Make sure the print media is straight and unwrinkled.
• Replace the used print cartridge with a new one.
• Toner is on the transfer roller. To help prevent this, do not load
print media that is smaller than the page size of the job to be
printed. Specify the correct page size in your driver or in the
Local Printer Setup Utility. For more information, see
the Local Printer Setup
• To clean the transfer roller, open and close the printer upper
front door. The printer automatically runs its setup cycle.
