4059-XXX
Print Quality - Background
Service Tip: Some background problems can be caused by rough
papers or non-Lexmark toner cartridges. If the rough paper mode is
on, turn it off and run the print test.
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.
