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. 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.

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.

Diagnostics - Self Test

Initialization Sequences

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 Chapter 2 - System Error Codes.

Entering Service Menu at Power Up - Only for Onsite Repair

If the Printer fails to initialize completely because of a System Error and you need to use the Service Menu (Service Tests and Utilities), the Printer can be powered up in Service Mode by pressing the Up and Enter keys while switching the Printer ON. This will give you access to some of the Service Tests and Utilities without having to complete the System Initialization (if you perform some of the tests, they will need to initialize the relevant part of the System).
