HP LaserJet Pro MFP M521dn toner cartridges

Q: Can I use a compatible or refilled cartridge?

You can, but yield, quality and level reporting vary. We sell only original HP cartridges.

The HP LaserJet Pro MFP M521dn uses the HP 55A (CE255A, 6,000 pages) black or high-yield HP 55X (CE255X, 12,500 pages) — genuine HP only, from $129.

The HP LaserJet Pro MFP M521dn is a networked monochrome laser all-in-one that prints, copies, scans and faxes for busy small offices and workgroups. It prints up to 42 pages per minute on letter paper (40 ppm A4) at up to 1200 x 1200 dpi, with the first page out in about 8 seconds, and automatic duplexing is standard.

A 50-sheet automatic document feeder and 3.5-inch color touchscreen make copying and scanning quick, and the 500-sheet input tray plus 100-sheet multipurpose tray hold 600 sheets. An 800 MHz processor drives it, Gigabit Ethernet, Hi-Speed USB 2.0 and a host USB port connect it to the office with AirPrint for mobile devices, the Super G3 fax runs at 33.6 Kbps, and HP rates the duty cycle at 75,000 pages a month.

The M521dn uses the genuine HP 55A and high-yield HP 55X cartridges. GS Toner stocks both originals, singly or as 2-packs, with free US shipping.

Standard vs high-yield

Why use genuine HP toner
