How to use
Power off and unplug the printer before attempting replacement. Allow the printer to cool if it has been in recent use, as the existing fuser may be hot. Open the printer service access according to the M4345 service manual, remove any consumables or obstructing modules, and carefully disengage the old fuser assembly by releasing retaining clips or screws indicated by the manufacturer. Install the replacement RM1-1044-080CN-RFB fusing assembly by aligning it to the chassis guides and securing fasteners. Reassemble removed modules, reconnect power, and perform any recommended firmware or calibration steps shown in the printer’s service instructions. Run a test print to verify correct installation and fusing quality.
Usage recommendations
Use genuine or OEM-specified replacement parts and follow HP service documentation for safety and warranty considerations. Regularly inspect paper path and rollers for debris, and use paper within the printer’s supported weight range to reduce wear on the fuser. If print defects persist after replacement, consult the printer’s error logs and service manual or contact an authorized service provider for diagnostics.
