Page yields for the HP 43X (C8543X) toner cartridge are measured using ISO/IEC 19752 testing standards based on 5% page coverage. High-volume enterprise environments often achieve excellent cost efficiency per page, though heavy graphics or dark background fills will reduce total page output relative to standard text documents.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| 43X | Standard | Black | 30,000 | $0.004 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Compatible cartridges.

Frequently Asked Questions
Why does the 43X (C8543X) cartridge include the imaging drum unit in a single assembly?
The HP 43X (C8543X) is an all-in-one cartridge design where the toner reservoir, drum, and roller mechanisms are contained in a single unit. Replacing the cartridge automatically refreshes the imaging components, ensuring consistent print density throughout the entire 30,000-page lifespan without needing separate drum unit replacements.
How should unopened 43X toner cartridges be stored for long-term inventory?
Store unopened 43X (C8543X) toner cartridges horizontally in their original sealed packaging, away from direct sunlight and extreme humidity. Keeping the cartridge flat prevents the micro-fine toner powder from settling unevenly inside the heavy-duty hopper prior to use.
Will print density fade before reaching the 30,000-page yield mark?
No, provided the toner cartridge is kept free from moisture and severe temperature shifts. Modern micro-fine toner formulation maintains uniform transfer efficiency across the full lifecycle, though gently rocking the cartridge horizontally when low-toner alerts first appear helps redistribute remaining toner evenly across the internal roller.
