My canon pixma ip6000d printer will not turn on

Have you thought that it might just "it's dead, Jim?" Honestly, I have worked on a printer that supports Infra-red connections in ages.

Try the standard "disconnect everything, including power", give it a couple of minutes, just for giggles, then connect just the power cord and make sure the surge protector it's connected to (you do use one, right?) is also switched on. Then try the power switch again. If that doesn't work I don't know what else to suggest. Electronics do age out eventually; printers have been just a buy & replace item because all the makers pull their profits from selling inks. Canon's own Selphy line (for compact photo printers) and current Pixma line are good replacements if you're dedicated to the brand. Personally, I've always preferred Epson for photo printing but that's just me.
