RISO MZ990 T64-539 error

[superphamicom]

Hi all, I recently cleaned out a drum and when attempting to print with it, had this error message returned:

T64-539 System Error

I reset the system as instructed and no dice. Does anyone have any advice or insight?

thanks in advance!

Ink motor lock. Try holding reset while turning on. What did you "clean" out exactly? And why?
Good luck.

thanks for your reply, I had a tech flush out the drum to prep it for a color change. I reset the machine and ran it a few more times and it ended up fixing itself!
