This may be a long shot, but since the price on this printer is now $1500 (with about $900 worth of ink onboard) I am considering replacing my HPZ3100 that I foolishly upgraded from Win7 to Win10 and lost my full function driver. Is anyone using this canon on Win 10 ok? Any recommendations or problems with the 6400? Clogging, print head , software issues? I know the printer is somewhat long in the tooth, but the price is attractive if it works on Win10 fine and print quality is high. Thanks for any info.
