Ordering supplies
To order 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:
The toner gauge is an estimate of how much toner is left in your cartridge.
•
All life estimates for printer supplies assume printing on letter‑ or A4‑size plain paper.
•
Ordering a print cartridge
When 88 [color] cartridge low or 88 [color] cartridge nearly low appears, order a new
cartridge.
Estimated cartridge yield is based on the ISO/IEC 19798 standard. Extremely low print coverage (less than 1.25%) for
extended periods of time may negatively affect actual yield and may cause cartridge parts to fail prior to exhaustion
of toner.
