Removal and replacement strategy
This chapter describes how to remove, replace, and reassemble the major assemblies of the MFP.
Replacement is generally the reverse of removal. Notes are provided to assist with any difficult
replacement procedures.
To identify the left side and right side of the MFP, face the control panel.
WARNING! Unplug the power cord from the power outlet (at the wall receptacle) before
attempting to service the MFP. If you do not follow this warning, severe injury can result.
Certain functional checks during troubleshooting might require power to be supplied to the
MFP. However, all power should be turned off and the MFP should be unplugged when you
remove any MFP assemblies or components. Never operate or service the MFP when the
protective cover is removed from the laser/scanner assembly. The reflected beams, although
invisible, can damage your eyes.
CAUTION The MFP contains components that are sensitive to electrostatic discharge
(ESD). Always perform service work at an ESD-protected workstation. If an ESD-protected
workstation is not available, discharge body static by grasping the MFP chassis before
touching an ESD-sensitive component. Ground the MFP chassis before servicing the MFP.
