If you will look where the power cord is plugged in, somewhere immediately close to there you will see a reset button or buttons similar to those you may find on electrical receptacles in the house. It is like a circuit breaker. Press it in to reset. It should be clearly marked as well.

    It is on the back of the machine to where the power cord goes into the machine. You should see some sort of red push button type to push in and reset the machine out of that error. It is like a circuit breaker for the machine in case it gets overloaded. Your model probably has more than one because it is a good brand. Let me know how it goes. God bless.

A Di-2010 has a co500 error after someone tried to run a transparency thru the copier.

This is a fusing unit malfuction. The fusing unit is the part that gets hot just before the paper exits the machine. The transparency issue makes perfect sense as if it was the incorrect material then it most likely melted in the fusing unit. A good tech can remove the fusing unit and the transparency material WITHOUT charging you for a new fusing unit. Then there is a service mode reset procedure for the code.
Good Luck.

Can i reset my Konica Minolta C250 transfer unit and fusing unit?? Is there a chip reset that I can buy for the transfer unit and fusing unit? I just purchsed the resets for the image units and they worked...

On your transfer unit there is a .80 amp fuse you can replace. this will reset your belt. make sure you use .80 amp or it will not work. on your fuser there is an inline 1/16 amp fuse next to the plug you can replace for that.

Problem replacing fusing unit for a Ricoh Aficio SP C411DN

Look in your owners manual for the set of reset keys you ppuch to reset the error in the machine. Can't tell you much other than it is a sequence like holding POWER button and 1 or 2 other keys for so many seconds. Have you tried to ask the question at their website?

Here is the location for the manual

2. Turn Main Power Switch ON while pressing the Utility/Counter key.
3. Touch [Trouble Reset].
4. Check to make sure that [OK] is displayed and the it has been reset.
5. After turning off the Main Power Switch, turn it on again more than 10 seconds after and check if the machine starts correctly.

2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary.
3 Change Fusing Unit
