Introduction
This chapter contains illustrations and step-by-step instructions to remove and replace
printer parts and components.
Removal and replacement strategy
This chapter explains how to remove and replace major printer components. (HP does not
support repairing individual subassemblies or troubleshooting to the component level.)
Replacement is generally the reverse of removal. Occasionally, directions for difficult or
critical replacement procedures are included.
Designations for the left and right sides of the printer are as if you are facing the front of the
printer.
WARNING!
The information in this section is intended for authorized service personnel only.
