DUMPING THE FUSER TEMPERATURE LOG

4.4 DUMPING THE FUSER TEMPERATURE LOG
The FCU monitors the fuser temperature and maintains a log of the most recent
temperature values. If a heating-related SC error occurs (error code "9-22"; SCs
541 to 552), you may wish to print out a dump of the logged data before clearing
the SC condition. The printout can then be submitted for analysis.
To dump the log, proceed as follows.
1. Before clearing the SC, use SP7-955 to write "02h" into address 40191C. This
freezes the log data.
2. Clear the SC.
3. Use SP-992 setting "3" (☛ 5.1.5) to print out a dump of addresses 401900 to
410CFF.
4. Use SP7-955 to write "00h" into 40191C. This will restart temperature logging.
