@pcamen Oh, ok. Yeah, rejuvenator is usually for pickup rollers that have dried up and started cracking. They no longer "stick" to the paper. Looks like you have the exact opposite problem.
I assume you've already looked at rollers and pads from other printers and thought about just replacing them?
Sure. If the Power key can be detected by software, you can have a little routine call the _Debugger trap. The Motorola 680x0 has a RESET instruction which could be executed for Reset. It wouldn't be exactly the same as the physical switches though, because it's dependent on your little routine being able to run.
