A curious question. A got a scrappy Canon MP230 printer/scanner. I removed all the printing parts and left only the logic board, control panel and the whole scanner. I want to make it a standalone flatbed scanner. So I plugged the whole thing in, installed drivers on my PC and turned it on. But the green and orange light flash repeatedly 6x. I understand, that the board evaluates this as a printer error, but the scanner should work just fine. On my PC, the drivers installed just fine, showing no errors. But scanning does nothing, not even showing any error. My question is: How to convince the logic board, that everything is OK with the printer even when it is not physically connected?
