Hello,

I am posting two extracts from the Active Solutions manual for the C6500. I haven't come across the code/problem you are facing myself, but hopefully these are of some help. Are you using the DU-102C drum units or the newer DU-104 meant for the C6000/C7000? Maybe a cleaning blade has flipped or some of the red screws haven't been removed prior to installing a new drum unit in the machine?

A. C-2211, C-2212, C-2213 or C-2214 usually when the machine is running in Thick Paper mode (1/2 line speed). These are drum drive error codes.

SOLUTION

PROBABLE CAUSES:

1. Incorrect drum speed. Please install minimum version 40 firmware to correct the drum speed. The latest version firmware is available via the Konica Minolta Download Selector. Access the Selector from SSD Web Support (CS Expert Support) by clicking on 'Download MSDS, Drivers, Firmware and more'. After installing the firmware please set the following DIPSW to the recommended setting: DIPSW 21 bit 6 bit 7 0 0 Default 1 0 0.1% up 0 1 0.2% up (Recommended) 1 1 0.3% up If the symptom reoccurs with the recommended value, try the 0.3% UP setting.

2. Cleaning blade has "flipped" on a corresponding color. Please refer to attached "Cleaning Blade Flipping" document if it is determined that the drum blade has flipped. To view the PDF, you may need to downloader free copy of Adobe Reader®.

3. Incorrect Belt Line Speed Adjustment setting. Check the setting by referring to section 10.3.8 Belt Line Speed Adj. (Printer Adjustment) in the Service Manual. If the setting value is not in the rang between -5 to -35, readjust the value within -5 to -35. If -5 to -35 cannot give the satisfactory result, also perform the section 10.3.3. FD Mag. Adjustment(Printer Adjustment).

4. Failed Drum Drive Unit. Replace the Failed Drum Drive Unit (p/n A03U R757 00 for Yellow / Cyan ) and p/n A03U R758 00 for Black / Magenta ).

B.C-2211, C-2212, C-2213 or C-2214 errors and the drum fails to rotate.

CAUSE: Cleaning blade damage or Drum Drive board (PRCB) has failed.

SOLUTION: Check the Drum Drive board for a failed ICP1 or ICP2.If ICPs are OPEN replace the Drum Drive board(p/n A03U R7B5 00). Also, replace the drum unit due to probable cleaning blade damage. Please refer to attached Bulletin Number 6833 for more information. To view the PDF, you may need to download a free copy of Adobe Reader®.

I would suggest to first check if the cleaning blade is okay.

If machine is in dirty environment it could be dirty encoder sensors on drum drive at the back of machine.
Little tricky to get them out to clean.
