Trouble code c0204 on km c250i

[Esron Thomas]

Hi guys I've got a Trouble Code C0204 on konica minolta bh c250i, I tried check for paper jammed, and debris, but nothing, tried power cycle, trouble reset, and system error clear but still trouble code c0204 exist, any idea?

Hi, this is an error to do with the tray lifting motor, it’s usually paper trapped behind the paper tray, causing the tray not to rise. Obviously it could be caused by the motor or sensor but I would start by removing the tray and checking for paper. I believe that code is tray 2 but I would check behind all trays, if there is no paper I would then remove the complete pickup unit and investigate further. Good luck!

Lol... system error clear for one piece of paper trapped

I've tried that, remove all the trays check but no paper stuck inside the sensor and the pick up unit looks perfectly fine, but the trouble code still exist

I physically checked but no piece of paper before doing system error clear..

likely an actuator stuck?

Thank you I'll try that out and keep you updated

I would have tried the sys error clear as well if no paper stuck. Did you test sensors for tray 2 in service mode?

No I didn't because did remote assistance with the customer via WhatsApp video call and I just told to check and clean the sensor (PS22) I guess?

Did you hit continue, confirm that you wanted to disable the cassette, turn the sub power off then on, then reboot the mfp?

Sounds simple, but have you open and closed the frontdoor without turning machine off and on? Rank B is reset by that.

We tried that several times but trouble code re-appears straight after the door closure

I tried that by isolating the tray 2 and the trouble code cleared, so I need your advice what is the real issue is, is it the PS22 or M13 faulty or other thing

Not much more to offer here for what the "real issue" could me. You have been given some good detailed advice to work with. You will need to troubleshoot the things mentioned above, i.e. checking sensors, lift motors in service mode. If you don't have a service manual I suggest you get one. Best of luck

I usually test MFUs in the following order:

Step 1. Take a working sensor from tray 1 and install it in tray 2.

• If the issue moves to tray 1, then...
• If everything stays the same, proceed to Step 2.

(You can check its functionality from the Service Menu under "Sensor Check." Open position = 0, closed position = 1. I think that’s how it works. In this mode, you can see whether the sensor responds when the tray is closed or lifted.)
This is what my working sensors look like when the second tray is closed (with no paper loaded):

Step 2. Take a working lift motor from tray 1 and install it in tray 2 .

• If the issue moves to tray 1, then...
• If nothing changes, move on to Step 3 ))

Step 3. Check the wires connected to the sensor and the motor.

PS. Make sure the paper lift mechanism (inside the tray itself) is functioning properly.

PPS. If none of the above helps, move on to the CPU board (CPUB) and software-related troubleshooting.

Beyond this, I don’t know how else to assist with your diagnostics. I think many engineers would agree with me.
