Printing with a cyan cast

[Rekusu]

What ho one and all,

I have an old but still, more than useful Cannon Pixma MP640 printer / scanner. Use it mainly to scan to pdf but very, very occasionally, the colour printer is useful.

Not overly concerned about the quality of the inks so I have refills fitted. However, the past X time I have used it and again today, when I was trying to copy a document, there is an overall cyan cast.. The document I was copying is essentially, white paper with printing and images on it but the white paper reproduces with a nice, even overall cast.

Have run all the cleaning options, and the test print, but make no difference. Last time I printed some photos with the printer connected to my computer, tried to tweak the setting to eliminate or reduce the cast, but it made no difference.

Is there any way to get the printer back to the factory settings with no cast. White paper should print with no ink whosoever but that is not happening.

Thanks and toodle pip
