I have a Oki Microline with an alarm of "roller Alarm". At start up the head goes to home as normal, but the rollers do nothing. I can try to turn the rollers at start up and they turn unitl the head goes home and at that time I can feel the rollers motor fight me for movement. once it goes to alarm the rollers free up again. makes me think I have a bad motor, but , I have seen boards do this to me too. I have no back-up to swap parts with.
Thanks
