Chapter 5 - Troubleshooting and Maintaining the 6820 Diagnostic information is updated and maintained by the printer. All diagnostic information is shadowed in RAM. At the end of every 50 forms, the flash information is updated from the RAM. The printer also updates the diagnostic information for nonrecoverable error, printer resets, printer self-test, and remote polling of diagnostic information. Fields are stored with ID first, then length, then data. The details of the data and the length of the entire field, including ID and Length bytes, are shown in the Diagnostic Information table. The amount of flash memory reserved for nonvolatile diagnostic memory is 16 K bytes. Printer self-test prints most of the information contained in the diagnostic memory for remote and end-user diagnostic access.
