Re: toshiba 5540c error code c381 reboot machine
Check the drive couplers:

=^..^=If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Re: toshiba 5540c error code c381 reboot machine
Firmware probably won't help. I think that I would focus on the electrical connections to the developing unit, specifically developer bias, and the condition of the mag roller. It's common for the developing roller to wear out at the rear bearing, or occasionally the front bearing, and the roller wobbles closer to the drum, sometimes causing arcing to the drum. Are you using OEM toner?
You might also check the condition of the primary charge grid and scorotron. If the primary charge is lost, the machine will rapidly de-tone the developer because it is making 100% fill black copies. When the toner is gone it starts taking the developer. =^..^=If you'd like a serious answer to your request:
