Xerox® WorkCentre® 3025 Multifunction Printer Service Manual
Report, EDC (Diagnostic) Mode
General Procedures and Information
Report
The following printed reports can be generated by the machine:
• Protocol
The Protocol report is used to check for send and receive errors. It shows the sequence
of the CCITT group 3 T.30 protocol during the most recent sending or receiving operation.
• Supplies Info
The Supplies Information report shows Toner Cartridge information such as toner remain-
ing, toner capacity, and toner product date.
• Configuration
The Configuration report shows the status of user-selectable options, and should be
printed to confirm changes made to machine settings.
• Error Info
The Error Info report shows a list of all machine errors since the last service call.
• Usage Page
The Usage Page report shows the number of duplex and simplex prints since the last ser-
vice call.
• Component Check
The Component Check report shows the results of component testing while in Diagnostic
Mode.
EDC (Diagnostic) Mode
The following diagnostic routines can be accessed in EDC Mode:
• NVM Initialize
The NVM Initialize routine provides the capability to initialize (set to default) machine con-
trol parameters stored in Non-Volatile Memory (NVM). Refer to Table 1.
• NVM Read/Write
The NVM Read/Write routine provides the capability to review and modify machine con-
trol parameters stored in Non-Volatile Memory (NVM). Refer to Table 1.
• DC330 Test Routines
This routine provides the capability to verify component functionality by monitoring input
signals and controlling output states. Refer to Table 2.
