Using Printer Diagnostics
Remove this section if you do not use the Control Panel MCU PWB connection for printer
troubleshooting.
FIPs often ask you to perform an output test or an input test. You use the printer Control Panel, recon-
nected to a specific P/J on the MCU, to access and run the Diagnostics that are presented in this manual.
The Control Panel LCD displays two lines of text, with sixteen characters per line. The text is make up of
printer codes and messages that are generated by the MCU PWB. The buttons are used to select and con-
trol Diagnostic functions.
Refer to the Section 7 for a detailed explanation of how to use the Control Panel to run the available Diag-
nostic routines.
