Replacement Procedures and
Illustrated Parts List
Organization of This Chapter
This chapter is divided into two sections.
♦ Section I: Replacement Procedures
This section consists of written procedures for removing and
installing the components that are replaceable at the field service
level of maintenance. Section I begins on this page.
The removal/installation procedures in this section will refer you to
the illustrations in Section II.
♦ Section II: Illustrated Parts List
This section consists of drawings of all the assemblies comprising
the printer. On the left page facing each illustration is a list of the
parts that are illustrated and their part numbers. Section II begins
with a list of figures on page 5–51.
In the parts lists, Ref means “Shown for reference only: the
component is part of another assembly, is shown for clarity, or is not
spared.”
Section I: Replacement Procedures
WARNING
Unplug the printer power cord from the power outlet before doing any
maintenance procedure. Failure to remove power could result in injury
to you or damage to equipment. Only apply power during maintenance
if you are instructed to do so in a maintenance procedure.
IMPORTANT
The components specified in this chapter are field replaceable units
(FRUs). FRUs must
be repaired at the factory. Do not try to repair these
items in the field.
DO NOT attempt field repairs of electronic components or assemblies.
Do not de–solder any circuit board components. Replace a
malfunctioning electronic assembly with an operational spare. Most
electronic problems are corrected by replacing the printed circuit board,
sensor, or cable that causes the fault indication. The same is true of
failures traced to the hammer bank: replace the entire shuttle frame
assembly. It is not field repairable.
