Konica Minolta CF2203 / Kyocera KM C2230 Error code C-0f36

**Ben Around** · 01-28-2016

I'm hoping someone remembers this old box and can give me an idea or two. (Kyocera KM C2230 Rebadged Konica Minolta CF2203)

The machine has a C-of36 error code which can be reset by opening and closing the front door. The error code indicates a low toner condition, but the copies are clearly over toned.

The Black imaging unit has approx 10k on it as it was replaced about 6 months ago. Any suggestions are welcome.

From the manual:
C0F36 Abnormally low toner density
detected Black ATDC Sensor
• T/C 3 % or less is detected ten consecutive times in
the Developing Unit as validated through the toner
replenishing amount determination control.

never heard of this model, but make sure the socket that the imaging unit plugs into has a good connection and is clean, the TCR sensor in the imaging unit may also be defective. (assuming its not in the bottom of the machine going through a window, then thats what i would be looking at too) After those are confirmed good i'd be considering printer control board personally.

are you sure the images are over toned and its not some other issue like a HV failure thats causing solid black pages etc and what is causing the low toner condition.

Thanks for the suggestions. I'm still trying to study the tech manual (between calls) to develop a troubleshooting strategy for this machine. You made some good points, thanks.

How old is that machine. Its a pain in the ass to take apart.

The tech manual has a date of 2004 on it.

I would be interested to have a look at it,

it is an LED printer like the CF2002 and C350 ?

Got any print samples to upload ?

Looks like it is the same as the C350.

I agree. It looks a lot like a C350 with a Sharp AR-FN7 finisher, but the toner cartridges are a little different. We had one of these as an office printer for a while, but we could not get it to talk to server 2012, so it wasn't very useful.

Damn. Haven't seen one of those in a long time. We used to have a lot of trouble with that toner feed assembly that the toner bottles fit into, especially the shutter that lets toner in. Have seen that code resolved by taking out, cleaning and repairing and reinstalling that unit. Sometimes had to replace the IU anyway. Pain in the you know what, but it might be worth a look

It maybe a Sharp finisher. I heard it was a Canon finisher too. I do know that finisher is an utter POS(at least the KM version was)... We got one from a c353 collecting dust in the warehouse.
