Hi
Any idea what causes this error, Door open MB Bill stacker open, and how to fix it? I had it come up on a denver duck that was running fine when it was turned off. When I turned it back on, this came up & I couldn't clear it. I got it running by putting another CPU in it. Now today, I have a Double Diamond that was turned on, running fine, sat idle for about an hour, and now has the same error??? Green batteries were removed from both boards. Strange how machine is working fine then just sitting idle, comes up with this error, no one opened the door or the cash can.
Thanks Dan
