Firmware Update
The Image Processor Board firmware can be updated by customers and service
technicians using Windows PC or Macintosh with dedicated utilities. Firmware
updates are available at www.xerox.com/office/P7500support.
Refer to “Firmware Update” on page 11-14 for detailed procedure.
Diagnostics
Two types of diagnostic functions are available:
1. Power On Self Test: The controller board is checked at every Power On. The
CPU, ROM, and RAM are verified by the boot loader for integrity before the
POST firmware can be loaded to verify the Controller Board, but other system
components are not required for POST to run.
2. Service Diagnostics: Only qualified service personnel can perform manual
diagnostics using the Service Mode in the Control Panel (refer to “General
Troubleshooting” on page 4-1).
