Premium Compatible Toner Cartridge

This True Color Toner 64435XA black cartridge replaces Lexmark OEM 64435XA and fits Lexmark T640, T642, T644, X642, X644, X646, IBM 1532, 1552, 1572, Dell 5210, 5310 and Unisys UDS 540, 544 printers. It delivers a standard yield of 32000 pages at five percent coverage for everyday office printing.

Ideal for High-Volume Mono Printing

Offices running the listed Lexmark, IBM, Dell or Unisys mono laser models will get crisp, dark text and sharp images at a lower cost per page. Buyers who need colour output, higher-yield cartridges or printers outside the compatibility list should look at other supplies.

Simple Drop-In Installation

The cartridge is designed to slide into the printer without tools or firmware updates; remove the seal, insert until it clicks and print. The most common issue is forgetting to pull the protective tape completely, which can cause light or streaky pages on the first few jobs.
