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.

Note:

All life estimates for printer supplies assume printing on letter‑ or A4‑size plain paper.

Ordering toner cartridges

When 88 Cyan cartridge low, 88 Magenta cartridge low, 88 Yellow cartridge low, or 88
Black cartridge low appears, order a new cartridge.

When 88 Replace Cyan cartridge, 88 Replace Magenta cartridge, 88 Replace Yellow
cartridge, or 88 Replace Black cartridge appears, you must replace the specified cartridge.

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 a color) 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.

Ordering photoconductors

When , 84 photoconductor low, or 84 <color> photoconductor nearly low appears, order a
replacement photoconductor.

When 84 Replace <color> photoconductor appears, you must replace the specified photoconductor.
