How do you rest an OKI c3530 image drum

Turn off the printer
Turn the printer on whilst holding down Menu button. (Display says user maintenance.)
Press the menu button three times. (The display will say drum counter reset.)
Press enter key. The system should go back on line, if not press on-line key.

You can just put a new fuse on the drum.
When you insert the drum the machine resets the counter and then blows the fuse. So if the unit is ok and you just wish to run it through another cycle just change the fuse.
This means you cannot just put a full unit in from another machine as it will not reset the counter until you put a new fuse in it as you found out.
This applies to drums transfer belt etc.
Note with regard to refilling the toner, some printers have 2 sections. 1 where you put the fresh toner and an after collection section in the same unit. You must empty the 2nd section if you refill it more than 2 or 3 times
