Maintaining Print Quality

Following are some suggestions for maintaining the
highest print quality from your printer.
• When the print output becomes light, redistribute
the toner. If light print persists, replace the toner
module or the photoconductor module. Refer to
Chapter 2 for information about replacing these
modules.
• Use high-quality paper or transparencies to obtain
sharp, crisp characters and maximum contrast.
Refer to Appendix D, Selecting Print Media, for
detailed specifications.
• Clean the appropriate parts of the printer. Refer to
Chapter 6, Maintaining the Printer, for instructions.
