This printer maintenance kit provides you with the parts most commonly used to rebuild HP LaserJet 4V/4MV printers.

Using the HP LaserJet Printer Maintenance Kit helps you eliminate repeat service calls and maximize the paper feed and

print quality performance of your laser printer.

Recommended Maintenance Level:

The parts included in this kit have a variable service life that is highly dependent upon printer applications, operating

environment, user maintenance and the print media used. Any printer servicing should include inspection of the

components, particularly in the presence of error messages and/or image defects.

Caution: Please be sure to refer to your printer service manual for detailed instructions

on how to remove and replace these printer parts.

Fusing assembly removal and replacement

The Fusing assembly is located on the upper portion of the printer door.

1). Remove the Transfer Roller

electrical characteristics, resulting in poor image transfer.
