Did you strip and check the toner hopper? The aluminium actuator clips out and the magnet can get a dirty build up that makes it stick.

Im trying that now. Is the actuator with the round spring on it?

Re: Konica Minolta C280 error C-2558

No, its the section were the toner feds from the bottle. Its a aluminium bracket with a magnet attached on the side, the auger inside the sub hopper tank pushes it to up and gravity lets it drop back down. There is a reed switch at the back of the hopper that switches if the magnet on the inside of the hopper gets close to it. If that gets stuck in the up position the machine would not add any toner.

You can stick you finger in the sub hopper to check if there is toner in there. the actuator can even clip out and cause the same problem.

You need to strip of the hopper assy and clean it out to make shur the is no blockage.

Watch your TCR levels before and after. Do half-tones to test your machine afterwards.

i tried cleaning them now. The black magnet was dirty I'm testing the machine now. I changed the chip that resets the black Dev tank. Seems to be working

I replaced a different tank with new Dev powder only

Hi there,

I had the same problem a few days before. If your developer unit works fine, with correctly developer level in another machine and you changed the developer powder, you only need use a new developer unit chip and the machine adjust it automatly. The chips have a SMD fuse that the machine need burn for do this automatic adjust

Bye!

I use the cheaper black tanks to replace the color ones. To reset the tank short out pin 1 and 5 on the connector while closing the door switch for less than a second. Same work for the drum counter use pin 1 and 3.

If longer than 1 second it will fry the boards Allan?

No its does not do any thing, just gives a code then just open and close the front door and try again. The timing is tricky that's all.

I have tried that on a C224e but it does not work the same maybe someone knows ow to reset that machine?
