Toshiba E450s (Lexmark X642e)

[panashiba]

We have been having some fax issues with our toshiba machine and I was wondering if anyone on the Lexmark side of this could help out. We have tried calling Toshiba tech support to no avail. They have no clue what to tell us since they are just reading what Lexmark decided to give them. We are having these codes on incoming faxes: E-802, E-804 , E-812, and E-713 . Our issue is, we have no idea what these codes are. None of the Toshiba documentation has error codes in it. Our customer does about 200 faxes a day and these errors pop up about 15-20% of the time each day. Is there a Lexmark service manual or tech out there that can point me in the direction of what each of these codes is?
Thanks for any help.

This may or may not help, it's the only thing I could turn up on the internet. If it does help let us know because as you said... there is not much out there from Toshiba. I just wonder if the lexmark uses a canon g3 board since your codes are all found on the page i posted. Alot of them point to HDD, I don't think that machine has a HDD though... I'd take them another fax as a loaner for a day and see if it happens. If so then... most likely a line problem, if not well you are back to square one: what's wrong with the lexmark.
