Preparing The Printer For Maintenance

WARNING
Always 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 and damage to equipment. If you must apply
power during maintenance, you will be instructed to do so in the
maintenance procedure.
IMPORTANT
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.
To prepare the printer for maintenance, follow the steps below.
1. Set the printer power switch to O (Off).
2. Unplug the printer power cord from the printer or the AC power source.
3. Disconnect all data (signal) cables from the printer interfaces.
4. Raise the media cover.
5. Unload print media.
6. Remove the ribbon.
7. Read the entire maintenance procedure before you begin working on the
printer.
8. Gather the necessary parts and tools before you begin working on the
printer.
