HP LaserJet Maintenance Kits

Some people refer to these as "fuser kits". What are they? Maintenance kits contain a fusing assembly, rollers, and separation pads that frequently wear out in printers. The fusing assembly is the component that bonds toner to paper through a combination of heat and pressure. If your printer display reads “PERFORM PRINTER MAINTENANCE” then your printer has reached its maintenance interval and a maintenance kit should be installed.
