HP LaserJet Pro MFP M521dw 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 M521dw 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 M521dw is a wireless monochrome laser all-in-one built for busy small offices that print, copy, scan and fax in volume. It prints up to 42 pages per minute on letter paper (40 on A4), gets the first page out in about 8 seconds, prints two-sided automatically and delivers up to 1200 x 1200 dpi output with HP ProRes 1200. The 50-sheet automatic document feeder scans both sides of originals for two-sided copies and scans.

A 3.5-inch color touchscreen runs scan-to-email, scan-to-folder and fax, and standard paper capacity is 600 sheets from the 500-sheet tray and 100-sheet multipurpose tray, expandable to 1,100. An 800 MHz processor with 256 MB of memory, Gigabit Ethernet, Wi-Fi and Hi-Speed USB 2.0 keep jobs moving, with HP ePrint and AirPrint for mobile printing. HP rates it for up to 75,000 pages a month. The M521dw uses HP 55A toner cartridges, with the high-yield HP 55X for up to 12,500 pages.
