5. Troubleshooting and Diagnostics

How to Use This Section

1.Find the category in which your problem occurs. The problem categories are: S Power-related Problems

S Error Messages S No Printout

S Operation-related Problems S Print-related Problems

S Ribbon or Carriage-related Problems

For example, if the print appears very light on the paper, look at Section "Print- related Problems".

2.Find the symptom description that most closely matches the printer symptom. In this example you would look at the symptom "Print faint or of poor quality."

3.Try the first suggestion under that heading.

4.If the suggestion does not cure the problem, try the next suggestion.

5.If none of the suggestions enable you to continue printing, or if the fault is not listed, contact your service office.

Each time the printer is switched ON the display indicates TEST while the internal self-tests are run. If the test is completed successfully READY 1 ELQ will be displayed. If an error message is displayed please refer to the following section.
