LaserJet M521
From HP's late-2000s mono lineup, the LaserJet M521 keeps the formula simple: black-and-white documents, single-function design, and the kind of mechanical straightforwardness offices kept running for a decade. A desk printer that treats printing as its entire job description.
The cartridge story is the HP 55A/55X family — CE255A standard, CE255X high-yield. Because that family spans dozens of HP models, toner for the M521 stays easy to source.

Frequently Asked Questions
Which toner cartridge does the LaserJet M521 use?
The LaserJet M521 uses the CE255A (standard yield) or the CE255X (high-yield) toner cartridge. Confirm the code printed on your current cartridge matches before ordering a replacement.
Why does the LaserJet M521 make grinding noises when printing?
Grinding noises from the LaserJet M521 can mean a mis-seated CE255A or CE255X cartridge or worn pickup rollers. Reseat the cartridge in the LaserJet M521 firmly; if the noise continues, the rollers may need cleaning.
What is the difference between the CE255A and CE255X cartridges for the LaserJet M521?
Both cartridges fit the LaserJet M521 identically; the CE255X is the high-yield version of the CE255A and contains more toner. For a LaserJet M521 that prints heavily, the CE255X means fewer cartridge changes.
