Section I: Replacement Procedures
WARNING
Unplug the printer power cord from the printer or 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 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 assembly,
sensor, or cable that causes the fault indication. The same is true of
failures traced to the hammer bank: it is not field repairable so you must
replace the entire shuttle frame assembly. Hammer spring assemblies,
the hammer bank cover, and the ribbon mask are the only replaceable
components of the shuttle frame assembly.
