C500 Error Code 23-09

[Stirton.M]

Description
F23-09 with lines, smudges or spots on copies.
Solution
PROBABLE CAUSES:
1. Insufficient airflow during idle causing internal machine temperature to rise. Toner is backing up or solidifying in the cleaning unit box for the transfer belt
causing the transfer belt drive motor (M18) to bind.
Replace the Belt Cleaning Unit (p/n 65LA R702 00) and install attachedSpecial Printer Control firmware(version 51-PBF0 for the 8050/CF5001 and version
12-PBF0 for the bizhub PRO C500 ).This firmwarekeeps M11 (Transfer Belt Cooling Fan) ON for a period after the copy process has completed which helps
keep the internal temperature at normal levels. The firmware can also be download from the Konica Minolta Download Selector. Access the Selector from
SSD Web Support (CS Expert Support) by clicking on 'Download MSDS, Drivers, Firmware and more'.
Note : Firmware version 51-PBF0 is primarily for the 8050, but can be usedfor the CF5001. When using the ISW tool to download the firmware please
select the 8050 from the drop down. If the CF5001 is selectedthe ISW tool will not see the file.
2. The paper exit fans (M61/M62/M63) DIPswitch is not turned ON.
Set software DIPSW 21-0 = 1 to enable the paper exit fans.
3. Dirty or failed transfer belt drive motor encoder disk sensor assembly.
Clean the transfer belt drive motor encoder disk and sensors. Replace the assembly (p/n 65AA -909 1E) as necessary.
4. Failed M18 transfer belt drive motor.
Replace M18 transfer belt drive motor (p/n 26WA 8001 3).

Re: C500 Error Code 23-09

Same problem here. Did all of the tests. Replaced the Printer control board, Transfer belt cleaning unit, swapped the transfer belt motor and sensors from another C500 that booted with the problem. Cleaned the waster toner auger. Checked the firmware and it is current, Dip switch is set to allow extended airflow etc. Have noticed that the motor spins intermittently when run in 47 mode 41 multi-mode 11,12,13. What could cause this motor not to spin. Bear in mind that the current one is from a C500 that boots without this error. Need some advice tofix this C500.

Re: C500 Error Code 23-09

Was hoping someone can chime in with an update. Did not want to start a new thread as everything described here is exactly how this machine is behaving. We are stuck. Have we missed something. The motor is fine as it is working in a another C500. The transfer belt seems OK. New transfer belt cleaning unit installed. The transfer belt roller are seated properly. New Printer control Board installed. The Waste Toner pipes cleaned. What else should we be looking for. What have me missed. Interestingly the motor does not spin in 47 mode - 41 multi-mode 11, 12 & 13. What could cause that? Really looking for some help here.
