#G2770
Hello, I'm trying to copy my thick books and in the manual said I can detach the document cover when scanning thicker stuff. I tried to do it, but only managed to lift it, but fail the "tip it back" instruction, I even push it back quite hard that i feel like it will snap. But still couldn't detach it. I need video guidance for detaching the document cover on Canon Pixma G2770.
