Workgroup Printing Pro Tip

Frequently Asked Questions
Do the Lexmark T640, T642, and T644 printers use the same toner cartridges?
Yes. The Lexmark T640, T642, and T644 printers share the same cartridge architecture, so the high-yield 64017HR black toner cartridge fits all three models seamlessly.
How does ISO/IEC 19752 page yield testing apply to real-world office printing on the T640 range?
ISO/IEC 19752 yields are calculated based on 5% page coverage standard text. If your office prints dense legal documents, barcodes, or heavy graphics, actual page yield per cartridge will be lower than the rated 21,000 pages.
Can I install standard yield 64017SR cartridges in a Lexmark T644?
Yes, standard yield 64017SR cartridges physically fit the Lexmark T640, T642, and T644 series, but high-yield 64017HR cartridges offer substantially better long-term cost per page for active office print environments.
What is the shelf life of a genuine Lexmark 64017HR high-yield toner cartridge when stored uninstalled?
Sealed in its original packaging and stored flat at ambient room temperature away from direct light, a genuine Lexmark toner cartridge maintains shelf life for up to 24 months without developer toner degradation.
