Our 4.8 Google rating proves it: we consistently supply premium cartridges backed by rock-solid reliability.
Expected output and component life
Enterprise mono printing demands predictable component longevity under heavy daily print workloads. Standard ISO/IEC 19752 testing methodology measures page yields at 5% coverage for laser printing. The W850H22G imaging drum is engineered for long duty cycles, delivering up to 60,000 pages before replacement.
Imaging drum unit specifications
The Lexmark W850 series uses a split system where the drum unit and toner cartridge are separate physical components. Experience Tip: The genuine W850H22G drum unit features a 60,000-page service life and outlasts multiple standard toner replacements before requiring replacement.

Frequently Asked Questions
Do the Lexmark W850dn and W850n printers use the same drum unit?
Yes, the W850dn and W850n share identical consumable specifications, meaning the W850H22G drum unit fits both printer models without compatibility issues.
How does page coverage affect the 60,000-page drum unit lifespan?
The 60,000-page rating is based on standard 5% ISO page coverage. Printing heavy black graphics, dense tables, or continuous large-format documents increases physical toner throughput across the drum surface, which may reduce practical page yield.
Is the drum unit replaced at the same time as the toner cartridge?
No, the drum unit and toner cartridge operate on independent lifecycle schedules. The imaging drum typically lasts through multiple toner cartridge cycles before reaching its 60,000-page service threshold.
What indicates that the W850H22G drum unit needs replacing rather than the toner?
Fading text across the entire page usually points to low toner, whereas repetitive marks, vertical streaks, or continuous background shading across pages indicate the imaging drum surface has worn down and needs replacement.
