I have a konica Minolta bizhub C250 and the screen is reading "replace transfer unit" and "replace fusing unit". I contacted a local repair guy that said he might be able to reset the counters and the machine should continue to work. Then he called back and said the new machines IE: Konica Minolta Bizhub C250 could not be reset and the counters are actually a microchip in the fusing unit and transfer unit. Is there any way to reset the counters and can you give me some direction?

I can only tell you they are definately resettable as I do it all the time.
The fuser "fuse" is located in the connector wiring. Once you get the fuser out just look in the area where the large connector is. It is a very small fuse similar to a resistor, green, and is encased in shrink wrap.
The Transfer belt fuse is behind a small black cover. If you pull the transfer belt unit out of the machine about 6 inches, it is located on the front right corner. In other words standing in front of the copier with the belt unit partially out it is on the corner closest to you. You have to remove a screw, a c-clip, a small metal plate and the small black cover is held on with a very small phillips screw.
