HP LaserJet Enterprise MFP M631 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 Enterprise MFP M631 uses the HP 37A (CF237A, 11,000 pages) black or high-yield HP 37X (CF237X, 25,000 pages) — genuine HP only, from $204.

The HP LaserJet Enterprise MFP M631 is a departmental monochrome laser all-in-one that prints, copies and scans, with the M631h and Flow M631z adding fax and workflow features. A 150-sheet document feeder, automatic two-sided printing and an 8-inch color touchscreen handle high-volume office work.

HP rates it at up to 55 pages per minute on letter paper and 45 images per minute in duplex, with a first page out in as fast as 5.3 seconds and up to 1200 x 1200 dpi output. The document feeder scans at up to 75 pages or 120 images per minute. Standard trays hold 650 sheets (100-sheet multipurpose plus 550-sheet tray) with a 500-sheet output bin, a 1.2 GHz processor runs the controls, and HP rates a 300,000-page monthly duty cycle with a recommended 5,000 to 30,000 pages.

It uses HP 37A toner and the high-yield HP 37X. GS Toner stocks both genuine cartridges as singles and 2-packs, rated for about 11,000 and 25,000 pages.

Standard vs high-yield

HP 37A is the standard cartridge (11,000 pages); HP 37X is the high-yield version (25,000 pages). If you print more than a few hundred pages a month, the high-yield cartridge usually has the lower cost per page.

Why use genuine HP toner

Original HP cartridges are built and tested for the HP LaserJet Enterprise MFP M631: the chip reports toner levels correctly, print quality and page yield match HP's ratings, and your printer warranty is not affected. Every cartridge we sell is factory-sealed original HP — never refilled, never compatible.
