s2000 door open m and paper out errors after moving game

[puckhead]

helped a guy out over the phone, but after moving the game, there is a problem. not sure if its related. the game had a board with  bad varta leakage, he purchased a very clean board with the varta removed.  after a successful clear and set up, the game worked like a charm. and worked consistanly well for a few days. then  he moved it from one house to another. now he gets a door open m, and paper out error.  in main door test, he gets alternating 0/1's.   in printer test he can advance or print a ticket. still, the errors persist. on start up, all looks good till the reels spin, then the errors.   it also initially had a bill validator comm error, but a netplex set up and crc check cleared that.  any ideas?

thanks

Find the paper censer on printer and clean it.  Check for belly door switch, bypass it.  (try pushing in on the belly door and see if it clears)
