I am getting an error code on my CS-1500 that says C-6 then 020. Unplugging and restarting do no good. Any idea what's wrong? Tom

That is a HIGH temperature detect error code.
Check the thermistor, if you measure 0 ohm resistance in the thermistor, replace it.

Press the stop/clear key, start key
and the left copy exposure adjustment
key in the order presented and hold
them down.
Press the stop/clear key.
Enter the number of the maintenance
item to be executed using the copy
exposure adjustment keys or the zoom
+/- keys.
Go to U163 and hit the Start Key, this will reset the trouble code.

Copystar cs-1500 fuser temperature problems

I had the same problem. And after spending as much time as you have. I replaced the fuser assembly. Problem solved.
It's not that expensive and how much is your time worth?
The hot line suggested I replace the main board and the intermitant board between the two. .......I still have them.
