Toner Cartridges, Maintenance Kits and Parts

One Item
The LaserJet 9055 uses a single toner cartridge, HP Q3681C. HP Q3681C yields 47500 pages.
The HP Q3681C cartridge has an approximate yield of 47500 pages.
A "Supply Problem" message on the LaserJet 9055 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 Q3681C will clear it.
