*  Codes listed above with 1 asterisk… these codes are confirmed necessary to reset specific fault codes (read below for a list of faults which definitely require resetting from the NVM.

** Codes listed with 2 asterisks… it is unclear in the manual if these actually require resetting from the NVM Read / Write or not.  Some of them will likely reset by turning the power off and back on.  If a machine seems “locked up” because of one of the related faults, it’s worth looking at the NVM codes to see if any of them are no longer showing a value of “0” as they should.

      

Fault Codes which require resetting from NVM Read / Write:

Remember to always solve the cause of the fault before resetting them in memory. 

010-319 (310-319) Fuser Heat Control Problem - resets with 744-351

010-320 (310-320) Fuser Overheat -  resets with 744-350

010-324 (310-324) Fuser Failure - resets with 744-352

042-326 (342-326) Belt Hole Sensing Problem - resets with 741-105

093-314 (393-314) Toner Dispense Problem (Yellow) - resets with 762-312

093-315 (393-315) Toner Dispense Problem (Magenta) – resets with 762-313

093-316 (393-316) Toner Dispense Problem (Cyan) – resets with 762-314

093-317 (393-317) Toner Dispense Problem (Black) – resets with 762-315
