Frequently Asked Questions

How do I know I'm buying the right toner for my LaserJet Enterprise MFP M631z?

Compare the code on the box with the LaserJet Enterprise MFP M631z's list: CF237A, CF237X, CF237Y. HP makes look-alike cartridges for different printer families, so a code match is your guarantee.

How should I store spare toner for the LaserJet Enterprise MFP M631z?

Keep spare CF237A cartridges sealed in their original packaging until the LaserJet Enterprise MFP M631z needs them — toner breaks down faster in heat and humidity. Store them flat in a cool, dry spot away from direct sunlight. Don't open a new cartridge until you're ready to install it.

How do I fix faded or streaky prints on my LaserJet Enterprise MFP M631z?

Check the toner level first — the LaserJet Enterprise MFP M631z flags a low CF237A before quality drops. Try reseating the cartridge and running a cleaning cycle from the printer's maintenance menu. If streaks persist with a fresh CF237A, the issue is likely elsewhere in the paper path.
