HP LaserJet Enterprise M604dn M604n Toner Cartridges
Your HP LaserJet Enterprise M604dn and M604n printers use the HP 81A and 81X toner cartridge series. Ink Depot has been supplying reliable consumables for these high-speed monochrome printers since Jun 2015. Our 4.8 Google Star rating shows that our customers consistently receive high-quality cartridges backed by reliable performance. Replacing standard 81A (CF281A) toner cartridges with high-capacity options or bundle packs helps high-volume departments maintain uninterrupted print workflows and minimise administrative handling.
Expected page output and replacement cycles
Standard page yields are measured in accordance with ISO/IEC 19752 testing standards for monochrome laser cartridges. Heavy document output with dense text or detailed graphics will deplete toner faster than standard coverage estimates suggest.
| Cartridge Number | Type | Colour | Page Yield | Cost Per Page |
|---|---|---|---|---|
| 81A | Standard | Black | 10,500 | $0.038 |
Cost Per Page = Total Cartridge Price ÷ Page Yield (at 5% coverage). Prices based on Genuine cartridges.

Frequently Asked Questions
Do the HP LaserJet Enterprise M604dn and M604n use the exact same toner cartridges?
Yes, both models share identical internal architecture and use the same HP 81A (CF281A) and 81X (CF281X) toner cartridge series. The 'dn' suffix simply indicates built-in duplexing and networking capabilities on the printer itself.
What is the difference between standard 81A and high-yield 81X cartridges?
Both cartridges share the exact same external dimensions and fit into the same slot. The 81X high-yield variant contains more toner powder, delivering approximately double the page output of the standard 81A (CF281A) cartridge for a lower cost per printed page.
How does cartridge page yield testing under ISO/IEC 19752 reflect real-world office usage?
ISO/IEC 19752 standardises monochrome laser yield testing based on 5% page coverage, typical of standard business letters. High-volume offices printing full-page text, dense tables, or barcode labels will experience higher toner consumption per page.
Will using compatible 81A toner cartridges affect print quality on enterprise printers?
Quality compatible 81A (CF281A) cartridges use formulated toner powder designed to match the fusing temperature and page speed of your printer, ensuring clean, smudge-free text output for general office documentation.
