Hi guys I'm stumped with this problem. I have a desktop with an amd a8 7600, 4gb ram and the latest windows 10. I have had a canon pixma ip7250 for over a year now and been very pleased with it's quality. It prints on both paper and printable discs. Recently though for no reason at all it has started to print a lot of colours like a negative. Especially anything meant to print black or dark gets inverted. I Havnt changed any settings or anything and can't seem to find a feature I might of accidently activated like a negative tick box in it's printing preferences. Any advice in what to try would be helpful I have searched the net and nothing has worked so far. Thanks.
