HP LaserJet Pro MFP M28 Supplies

The HP CF248A cartridge has an approximate yield of 1000 pages.

A "Supply Problem" message on the LaserJet Pro MFP M28 usually points to a chip-communication hiccup rather than an empty cartridge. Power-cycle the printer (off for 30 seconds, then on), reseat the cartridge until it clicks into place, and gently clean the gold chip contacts with a dry cloth. If the message returns, a replacement HP CF248A will clear it.
