Minolta CF2002 Code C-OB4C

What is the code!!!!!!

High Voltage Board might have gone bad. IF you can find a replacement board. A legacy Minolta machine. Minolta is now Konicaminolta 3rd party best bet! mite reset all the image units, try.

Could not locate the code in the service manual please check again came close to software fault, see if you can get a Konica Minolta Technician to see if it is possible to down load firmware fro the KonicaMInolta Web site (SECURE) if possible.

C1183 is for Finishing Option Elevator Drive Failure. Most of the time when I see this code it is because 1 or both bins are not fully inserted into their slots. The bins when all the way in will trip small switches to tell the machine where the bins are. In your case this may not be true due to the noise you are hearing unless the elevator has already driven the unit all the way to the top or bottom.
C11BO is for Finishing Option Stapler Unit CD Drive failure. I have never seen this code come up before but as you can see, both of these codes are coming from the Finishing Option which you have just installed. It is very possible that the unit has some shipping or other damage and there is nothing you have done wrong. If it were just the C1183 I would feel differently.
I would start by checking the stapling unit and make sure that you got the packing tape and materials out of the inside of the finisher that hold the stapling unit during shipping. Most likely the 1183 code was from the bins but I am not sure of that as it could also be a shipping damage issue. Hope this helps!
Good Luck and Thank You for using Fixya.

Hi

Error code C1183 means finishing option elevator drive malfunction. It appears due to tray lift motor failure on the finisher. To trouble shoot the issue turn off the power and open the elevator section to check the elevator motor. Wait for 2-3 minutes and check if the issue is resolved. If this doesn't work then check the alignment of front and rear rollers of the finisher. Also make sure that the finisher exit guide rollers are fine & the paper is exiting properly, open both rear and the front cover and check the lower gears attach is the up/down drive belt. Sometimes this error may appear due to a broken lower gear by the pin slot. Hope this helps...

The C0016 code means that the Black Imagine Unit's Motor is not turning. So you will need to check all the connections and connectors on the black imaging unit and try re-installing. You could replace it if you have a spare.
The 31C-M code is not in my service manual and I have never seen that code before.

Is there a manual available for such errors.

There is not a C0876 listed in the service manual. Perhaps it's a C0B76 - Finishing option Punch Unit Board Malfunction.
CAUSE: The shaft on which the gear rides is deformed. The punch unit cannot be driven from front to rear.

SOLUTION: Reform the shaft toward the punch unit rail. This will allow the drive gears to mesh properly so the punch unit can be mechanically driven from front to rear.

First check the alignment front and rear of the finisher, check the finisher exit guide rollers if the paper is exiting properly, open both rear and the front cover and check the lower gears attach is the up/down drive belt. that lower gear one might be broken by the pin slot.
