I am getting a system fault on my Doc 12. The code is 9-343. When I turn it on there is the sound of a clutch grinding. It grinds twice for 1 second each and then I get this error code. The sound comes from the left side odf the machine.
I am looking for help on this issue and someone who can service it in the Toronto Ontario area. Any help would be appreciated. Thank you

i had similar problem a week ago running black only job on extra heavy card stock. there is black toner built up. when you run black only copy with little toner use, it builds up toner in black developer and motor could not run. always mix black and color jobs and run alternate, so there is no excesses in any color. or cheaper way how i did without paying color clicks. i got rid of excess black in following manner. took 11x17 white sheet, copied as negative (solid black) and ran 30-50 black copies, which drained all excess black and then continued with job. hope it works for you or get professional help or you will lose motherboard and motor if you just follow instruction as it tells you on error screen... switch off and switch on. do not keep on repeating.

You Have to Clean a litle square reflexive patch that is located on the IBT Belt.
Just remove the waste developer botle, turn the orange handle CCW, remove the 2 external screws of the IBT Assy and pull out the Transport drawer and IBT drawer. clean the patch reinstall and thats it.
