Code 78 makes all black copies. Hello againI was able to enter simulation mode for the CS-2114

Question

Hello againI was able to enter simulation mode for the CS-2114 copier as you said. I pressed in 78 and pressed print and it went to "98" (96?). I pressed a few buttons after nothing seemed to be happening and nothing again, and pressed stop/clear to exit. Powered machine on again and now get all black copies. How do I get back to where I was?thanks
