Our minolta ep4000 is showing an error code co200. We've been told the part is not available anymore but he cleared the code and it worked for a couple of weeks. We are in the process of getting another copier but until then can someone tell us how to clear the code?

C0500 refers to a low fuser temperature. You can attempt to clear the code by using the tech rep service mode. Go to "Counter" Go to "Trouble" Trouble reset If "warm Restart Swich" is asked for- This can be actuated through a small access hole on the right side of the control panel, using a straightened paper clip or something similar. You may need to clear the counter by pressing "clear" and then "end". After clearing the code, power cycle the copier. If it comes to "ready" you are all set. If not, you may have a blown heat lamp or thermal fuse which would need to be replaced by a technician. Good Luck!!

Did you do anything to the fusing unit (ie cleaning thermistors or replacing the fuser roller?) That code means you have a temperature problem.  It will also come up if your power cord is loose.  You can check it by taking off the back cover of the copier and pressing in the trouble reset button while the copier is on.  It's a small black button. If the code goes away, you're good to go. If it comes back, you might have to replace some of your fuser components.

I've had this a couple of times. Bit of a pain the black & white 250's for this fault.

Basically when you change the drum (and dev) you need to go into service mode anf run an F7 asap.

If the machine doesn't allow you to run an F7, you need to go into counters and reset the drum/dev one.

Bit of a pig cos all you're hearing is 'bee-bo-bee-bo'!

Ask you service guy if he can or knows how to rebiuld your IU / drum unit. You can still get parts for that copier you probly need a new OPC drum and cleaning blade and a developer change. I belive they should last for 80k copies more or less. Are you getting black lines and bad copy quility? If not you may just have the PM / IU light ON or it is asking for a PM? It is just a counter in the copier that say's it time to replace the PM parts. They may have been replaced , but the counter was not reset. On a final note, this is one model in a long line of the same machines with alot of the same parts. I don't think it is hard to find these parts. You can buy them on line.. Under copier part....
Order the parts your self and save money and have them install them... Good Luck
