Maintaining the printer
Periodically, certain tasks are required to maintain optimum performance of your printer
Warning—Potential Damage: Failure to replace parts and supplies when directed, may cause damage to your
printer or may prevent the printer from performing optimally.
Ordering parts and supplies
To order parts and supplies in the U.S., contact Lexmark at 1-800-539-6275 for information about Lexmark authorized
supplies dealers in your area. In other countries or regions, visit the Lexmark Web site at www.lexmark.com or contact
the place where you purchased the printer.
Notes:
• Each gauge displays the estimated life left for the supply or part.
• All life estimates for printer supplies assume printing on letter‑ or A4‑size plain paper.
Ordering a toner cartridge
When a message on the printer display indicates which toner cartridge needs to be replaced, order a new toner cartridge
immediately.
For information on replacing a toner cartridge, see the instruction sheet that came with the supply.
Estimated cartridge yield is based on the ISO/IEC 19798 standard (with about 5% coverage per color). Extremely low
print coverage (less than 1.25%) for extended periods of time may negatively affect actual yield for that color and may
cause cartridge parts to fail prior to exhaustion of toner.
