Machine runs 5 to 6 sheets then errors with error code C-4840. When i get the jammed paper out i find that on the sheet it jams on it prints half way down the sheet instead of starting at the head of the sheet like it should.
Anyone have any experience with this? First time I have came across this code.

Service manual says its caused by the printer control program.

The only info I have on that (and only on the C6500) is to flash the latest firmware first and, if that doesn't solve it, to replace the MCB.

Never had it myself. Let us know what you find out.

That seems to have been it. Firmware was all current but I flashed it anyways. 1000 sheets in and it seems fine. Thanks for the help. Waiting a couple of days for our tech to show up was not going to be any fun.
