EN Chapter 6 Removing and replacing parts 135
Removal and replacement strategy
This chapter describes how to remove and reassemble major assemblies.
Replacement is generally the reverse of removal. Occasionally, hints and notes are included to
provide direction for difficult or critical replacement procedures.
WARNING! Unplug the power cord from the power outlet before attempting to service the printer. If this warning
is not followed, severe injury can result.
Never operate or service the printer with the protective cover removed from the laser/scanner assembly.
The reflected beams, although invisible, can damage your eyes.
Some sheet metal edges, particularly around the formatter cage, are sharp. Be careful when working
in these areas to avoid cutting yourself.
CAUTION The printer contains parts that are sensitive to electrostatic-static discharge (ESD).
Always perform servicing at an ESD-protected workstation. The ESD symbol
appears in this chapter when the parts being serviced are especially susceptible
to ESD damage.
CAUTION If possible, print the configuration page and menu map before working on the product. Replacing the
formatter assembly clears the settings in memory. Clearing the settings can render the product
inoperable. The list of configuration settings can assist in restoring the settings.
CAUTION To install a self-tapping screw, first turn it counterclockwise to align it with the existing thread pattern,
then carefully turn clockwise to tighten. Do not overtighten. If a self-tapping screw-hole becomes
stripped, repair the screw-hole or replace the affected assembly.
