  • Page 2: Self-Diagnosis Function

    SELF-DIAGNOSIS FUNCTION The self-diagnosis function consists of error codes for customers which are displayed automatically when errors occur, and error codes which show the error history in the test mode during servicing. For details on how to view error codes for the customer, refer to the following box in the instruction manual.
  • Page 3 ITEMS OF ERROR HISTORY MODE ITEMS AND CONTENTS Selecting the Test Mode Display Details of History total rec Displays the recording time. Displayed as “rππππππh”. The displayed time is the total time the laser is set to the high power state. This is about 1/4 of the actual recording time.
