Introduction This chapter explains how to use the built-in Service Tests and Service Utilities and what to do if any of the Service Tests fail. NOTE: If possible, always perform a Service Test on the component that you are about to replace, just to make sure that is the component that has failed. If the test on that component passes, there is no need to replace it. Diagnostics - Self Test Whenever the Printer is switched ON, it automatically performs a series of internal self tests and mechanical initialization sequences. If any of the parts fail, a system error will appear and you should consult “System Error Codes” on page 43.
Phone Support In certain circumstances, a Call Agent can try and troubleshoot the Printer by requesting the Customer to perform a Service Test via the phone. Using this process, it can be determined whether the Printer requires any on-site maintenance. Remember that the Key combination for the Customer to Enter the Service Tests and Utilities is different from the one that the Customer Engineer will use. Service Tests (Diagnostics) The following is a list of all internal Service Tests available in the Printer. See page 94 for instructions on how to enter the Service Tests menu. 1.
