Removal and Replacement Strategy
This chapter documents removal and replacement of major
assemblies.
Replacement is generally the reverse of removal. Occasionally,
information is 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 may
result.
Never operate or service the printer with the protective cover removed
from the Laser/Scanner assembly. The reflected beam, although
invisible, can damage your eyes.
This printer has some sharp, sheet metal edges which can cause injury.
Hint
To install a self-tapping screw, first turn it to the left until it clicks,
indicating the threads are seated. Then, turn it to the right to tighten.
Do not over-tighten
. If a self-tapping screw-hole becomes stripped,
repair of the screw-hole or replacement of the affected assembly is
required.
CAUTION
The printer contains parts that are electrostatic discharge (ESD)
sensitive. Always service printers at an ESD-protected workstation.
Required Tools
●
Phillips #2 magnetized screwdriver (6-inch shaft)
●
Small, flat-blade screwdriver
●
Small, needle-nosed pliers
All screws used in field-replaceable printer components are Phillips
head screws that require a #2 size Phillips screwdriver. Figure 6-2
below shows the difference between a Phillips and a Posidriv
screwdriver. Note that the Phillips tip has more beveled surfaces.
