Or you could replace the machine and keep the old one as a donor machine for mfp/print control boards/scanner assy/df assy/ print head etc etc which all fail at fairly regular intervals (especially if you have a lot of these in the field). I would be pretty sure that the cost of a new machine would be a lot less than the individual cost of these items. If you include the work time involved as well. Someone needs to do the sums.

How hard is it to get the gear box out?

Konica just can't seem to make a decent small machine. I cringe every time I get a call on one of these.... Has it always been like this?

I am thinking about manufacturing the 2 gears out of brass, the one that rounds out in the middle and the one with the shaft that goes into it. (normally both plastic)

I am only thinking about it at this stage, it there was sufficient interest i may consider putting the gears on ebay or some such. They wont be cheap, but will be cheaper than throwing the machine away.

It takes a full day to replace them however so it's only worth doing if you've got spare time. It really is not a field repair, you need to take A LOT of stuff off to access the main drive. It is not designed to be removed.

Machines applicable would be the c25/C3110 & C35/P

I also discovered the C3350/C3850 also uses the same plastc flimsy 1st transfer retraction drive planetary gear set, but at least on those the main drive is designed to be replaced and is available as a spare part. Look forward to the same errors on those too. But they have their own problems with defective black imaging units and transfer belts falling to pieces and jamming inside the machine requiring brute force and ignorance to remove.

Just got this code on a machine. I don't think Konica made this box. I think someone else did and they sell it.

PWB-A has KM part number silk screened on it along with NCU card. MFP board has KM branded asics all over it. Doubt anyone but KM made these machines.

Good to know, thanks for the info.

It doesn't show a like or thank but tells me but tells me "You do not have permission to undo a button click."

Also still have this issue, I know it's not the sensor as I've swapped it with another (seems all the sensors are the same in this box per the part manual) the drive feels true to it as I've turned the motor and engaged the solenoid and it does turn without problem, even if I put some resistance to it.

Any other thoughts guys?
