Maintaining the printer 189 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 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.
