Using the Troubleshooting Procedures
1. Each Step in a Troubleshooting Procedure instructs you to perform a certain action or
procedure. The steps are to be followed sequentially until the problem is fixed or resolved.
2. The Actions and Questions box contains additional information and/or additional
procedures you must follow to isolate the problem.
3. When a procedure instructs you to test a component using service diagnostics, see the
Service Diagnostics Menu Map on page 2-5 for the detailed steps and functions for testing
parts of the printer.
4. The action is followed by a question. If your response to the question is “Yes ”, then follow
the instructions for a “Yes ” reply. If your response to the question is “No”, then follow the
instructions for a “No” reply.
5. Troubleshooting Procedures may ask you to take voltage readings or test for continuity at
certain test points within the printer. For detailed diagrams, see Section 7, Wiring Data on
page 7-1 for complete information on test point locations and signal names.
6. Troubleshooting Procedures often ask you to replace a printer component, see Repairs and
