When using the copy function of my MG6320, the printed page will come out with a grey, boxy pattern all over, going from lighter-grey to darker-grey across the page like a gradient.
But this pattern does not appear when copying using the "high" quality setting.
Any suggestions as to the cause would be much appreciated. Having to copy each document on "high" is a massive slowdown, and I'd like to remove this time-block as soon as possible.
