Chapter 3 Troubleshooting Procedures
Troubleshooting Procedures
Troubleshooting procedures are listed in this section. Every troubleshooting
procedure has three parts:
MESSAGE / MALFUNCTION — The LCD message or a description of
the malfunction
1. TEST / INSPECTION / EXPLANATION — Numbered steps that provide
information and tell you what to test or inspect
CORRECTIVE ACTION — Actions to take as a result of tests or
inspections
How to Use the Troubleshooting Procedures
1. Find the message or symptom you want to troubleshoot in the Message
List (page 31) or the General Symptom List (page 36). The lists tell you
which page the troubleshooting procedure is on. Go to that page.
2. Start at step 1 of the troubleshooting procedure. Each step has corrective
action(s) indented below it.
3. Test the printer after every step and corrective action.
4. Work sequentially down the steps until the problem is solved.
STOP troubleshooting as soon as the problem is solved.
5. Reinstall any original parts you replaced earlier that did NOT solve the
problem.
6. Reassemble the printer and give it a final test.
