The Patron BUSH-HP-4200-PN rubber-roller bushing set is a printer fuser component designed to support the rubber roller and press it against the thermal unit. The bushings help the roller move as paper passes through the fuser during printing.
Made of plastic, this set is intended for HP LaserJet 4200, 4250 and 4300 series printers, including 4200dtn, 4250n and 4300tn models. The listed fit makes it a replacement option for worn bushings in those printer families.
Wear, squeaking during printing or smudged text are listed as signs that the bushings may need replacement. The set provides the roller support parts for servicing the fuser assembly.
