REPLACING THE PRINTHEAD
Use these instructions to replace the printhead assembly in the 9417 Printer.
Audience
These instructions are intended for a skilled service technician only. For additional information or
assistance, call Service at 1-800-543-6650.
Cautions
The 9417 printer contains devices that are sensitive to electrostatic discharge (ESD); failure to
exercise caution can damage the printer. We recommend using an ESD wrist strap, grounding
mat, or grounding workbench when performing maintenance on the printer.
Flex connectors between components and board assemblies are extremely fragile; when
damaged, they require component or board assembly replacement.
Required Tools
The procedures require the following:
A hard, dry surface to set the printer on
Phillips screwdriver
Tape (can be clear adhesive tape, black electrical tape)
