HP LaserJet Enterprise MFP M631h toner
Your LaserJet Enterprise MFP M631h takes the 37X (high yield) and 37Y (high yield). At our price that is about 0.3¢ a page.
The HP LaserJet Enterprise MFP M631h is a mono laser printer in the LaserJet Enterprise MFP M631 series, which shares cartridges across 4 models.
It takes 2 cartridges: the 37X and 37Y.
On this printer the drum is built into the cartridge, so there is no separate drum to buy or reset. Every new cartridge brings a fresh drum with it.
When you compare prices, compare cost per page rather than the sticker price: a cheaper cartridge with half the rated yield costs more to run. Every cartridge here ships free, is covered by our printer damage protection and can be returned within 90 days, opened or not.
