S2000s stack errors remember? So if you pulled the printer out that gives an error (#1), remove the paper, that's error #2, pull printer again, there's error #3, and so on. Closing the main door "clears" ONE error at a time, and the display will not change until the very FIRST error is cleared. So, close the main door and slowly lift up and down on the door latch about 6-7 times. Latch needs to go all the way up, and all the way down.
If this doesn't work, but I really think it will, we can do an Auto-Config in menu 4. That will, many times, wake up a device (printer or BV, for example) that has errored out.
Report back and let us know where you get Don!
