Phaser 7760 Error 004-350

[Gabber]

As best I can tell the error 004-350 is a firmware problem.

I tried to update firmware through the terminal on a Mac, and could not make it work.

I did as they said at tech support: reboot with a 45 second delay.

The problem came on shortly after installing new image drums.

Can anyone help?  what can I do to make this baby work

I could be wrong but a 4- is a drum drive or similar issue. Sounds like a bad new drum that is binding up.

I have found this is usually caused by a bad imaging unit. I've had this error twice now and both times it was a bad imaging unit.
