Our maintenance kits and fuser assemblies are compatible with some of the most common and well known printers like HP, Lexmark & more. The products that we offer use the finest materials possible and are engineered to run quietly and save on energy consumption. Printers over time will need a fuser replacement. A fuser is responsible for melting the toner into a printed page. A fuser replacement will cover the fuser, the transfer and pickup rollers, the separation pad and written instructions. The reason that these items need replacing is due to normal wear and tear and the high temperatures that these parts operate at.
