DI-7210, I'm guilty as charged !!!!

Ok I made one of the Minolta serv tech sins. Not sure how critical it is on other OEM's but is with Minoltas. I unplugged and plugged back in a few connectors while the machine was on! I know better but it was one of those days and I was in a hurry. I had removed the stapler unit to remove a jammed staple and after plugging the connectors back in I realized the machine was still on. Now when you go to make a copy it scans the original, machine runs but never feeds the paper, diagram of copier flashes for like a second then back to basic screen. displays reads press start to restart, if you press start it does the same thing all over again. I tried unplugging the power for 10 mins but that did not help. I suspect I took out a PWB? Any ideas? Thanks for any help.

Have you tried running it with out the finisher attached? I would guess that there is an issue with the finisher board since that is where you were working.

Also, I wouldn't go around plugging and unplugging any connectors on any copiers while the power is on. Not unless you like replacing boards.

yes first thing i did was disconnect the finisher and still the same problem. like I posted I know about unplugging/plugging connectors with machine on. been a tech for 30 yrs. maybe the mind is slipping a little, could be all that fedron & toner I have inhaled over the years :-)

I would think if you plugged in a hot finisher connector and it is now acting crazy, a firmware rewrite may be the first step.

Can you print a meter page or anything from tech mode? Any codes in the history that might not have showed on the screen? If you aren't getting a code, jam or other message, I'm with Jerry. Update the ISW and start from there. After that I'd swap out boards starting with the main board and then others.

I know we used to be able to get away with this on the older analog machines. Ah, those were the days...
