FRU Disassembly
This section contains step-by-step removal procedures for a specific component or
assembly. Numbers in the illustrations refer to steps in the procedure. For example: if
step 3 in a procedure instructs you to remove a screw, the screw in the illustration is
labeled 3. Unless a specific Replacement procedure is included, reassembly is the
reverse of disassembly.
Illustrations are used to assist you with the procedures. You should refer to the
specific Parts List illustration (listed under the repair title) for locating most
components within a procedure.
Caution: Always reinstall the correct type and size screws. Using the
wrong screw can damage tapped holes.
Caution: Do not use excessive force to either remove or install a part.
Locations, such as left, right, front, or rear, given in the repairs assume you are facing
the printer front panel.
The Print Cartridge should be removed and stored in a dark, safe place when
performing any procedure where screws or components may damage the cartridge
and where exposure to light could degrade performance.
