Hi, I have a Canon Pixma725 and it last printed successfully on 17th September. Then when I tried to use it again on 27th it's not been recognised. The scanning function worked. I've tried all the usual restarts, uninstalling and re-installing, using the original disc and the drivers from the Canon website, deleting print spool etc. All to no avail. I've looked to see if there's an update I can delete that matches up with the dates, but nothing seems to tally up. Any suggestions you can offer would be gratefully appreciated.
