Xerox WC7425 Style Technical Info-Part II

(Diagnostics Mode for Component Control and Testing)

Xerox® WorkCentre 7425, 7428, 7435 & 7525, 7530, 7535, 7545, 7556

Last month we began looking at the full color Xerox brand 7425 series copiers / multi-function machines. We covered the fault code meanings and a few other topics.  Now let’s learn more about using the Diagnostic mode, particularly for the purpose of testing parts of the machine in dC330 – Component Control mode.

To get to Component Control, you’ll need to enter Diagnostic Mode (CE Mode).  Press and hold the ‘0’ button for 5 seconds, then while you’re still holding ‘0’, press ‘Start.’  This will bring up the CE Passcode screen.  Enter ‘6789’ at the prompt and touch ‘Confirm.’  Next press the ‘Machine Status’ button.  Select ‘Tools’ followed by ‘System Settings.’  Now in the ‘Group’ column choose ‘Common Service Settings’ and in the ‘Features’ column, scroll down and choose ‘Maintenance / Diagnostics.’  Within this menu you will find ‘IO Check’ is one of the choices, and that will bring you to Component Control.

The rather lengthy list of components is broken into two categories.  First there are the Input Components, which include parts such as sensors and switches.  Then there are the Output Components which include motors, clutches, solenoids, and lamps. The following list is shortened considerably to preserve space. Where there were multiple codes which run the same component, the duplicates were dropped out.  For example, if a motor can be run in 3 different speeds, you’ll find only one of the three speed listings shown in our list below.
