Print Quality - Background
Service Tip: Some background problems can be caused by rough
papers, non-Lexmark toner cartridges or if the media texture is set to
the rough setting.
Some slick or coated papers may also cause background. Some
problems occur with printers that run a large amount of graphics in a
humid environment. The customer may try to improve the print
quality by increasing the transfer setting.
Check the charge roll to make sure it is not at the end of life.
