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
