Service Mode Diagnostic Tests
The diagnostic test procedures for the Phaser 6600 and WorkCentre 6605 printers are documented in
this section of the chapter. In the procedures that follow, the screen displays shown are for the MFP.
The Printer Diag tests for the MFP are the same as the Service Mode tests for the SFP. Therefore, if you
are working with an SFP, you can ignore the step to confirm that Printer Diag is selected, and you can
substitute the term Service Mode for Printer Diag.
ESS Diag
This section explains the details of the ESS Diag tests.
