Konica minolta c280 showing error codes 3423, 3334 and 2451 How can I clear the codes

SOURCE: copier malfunction

Code C0F36 is a low toner density error on the black developing unit.

Was it asking for black toner before this code appeared?

c3852 means low fuser(hot section) temp setting. hold down utility or stop key, then you should be abel to do trouble reset. if problem persist it would most likely be a lamp or a sensor, which will require a technician to come out.

I have a Konica Minolta CSPRO EP1054 (in the Middle East)

I accidentally plugged the EP1054 copier into a 110V outlet instead of the 220V. Immediately the malfunction code (error code) of "C05" appeared along with the "Call Tec Rep" indicator light (wrench).

I followed the instructions posted by "Soul Visitor" ... i.e., I found the "Trouble Reset Switch" (not shown in the user manual) by opening the upper back panel and pressing the small black button in the lower right hand corner of the middle circuit board (green).

It worked perfectly!

Since you did not include the Model number I will suggest the following:
This code means pretty much the same on all Konica/Minolta machines.
The ATDC or automatic toner density control has experianced a problem. Have you run the copier out of toner by chance?
You can try resetting this code to see if it comes back. If it keeps coming back then you are going to need the process unit serviced. Or depending on the model you can replace the "Imaging Unit" yourself.
