I have two canon S630 printers. In the past few months, twice or 3x now, one ink tank has shared itself with the others. I noticed when first the output was all blue. I opened the cover and removed the cartridges and the red was purple and yellow was green.
I swapped the print head from the one I had that was working fine and it was all good for a while. Now the red has blead into the yellow, making orange and my print outs are a lovely shade of pink...
This cartridges go from left to right, cyan, magenta, yellow. This time the blue... left was unaffected.
I did a quick google search for canon tank ink bleed, but found nothing. Any ideas?
