Was wondering if anybody has taken firmware backwards. I updated this copier to newest firmware and am having problems with it. When customer enters accounting codes it will intermittently lock up with Please Wait in the display. When I am in sim mode I sometimes get a page that does not have the sub codes, or when exiting sims it will say exiting simulation and just hang. When any of this happens I have to use the main switch to power off machine. Would like to take it back to previous firmware but not sure if it can be done. Any insight is appreciated.
