what causes the trapezoid image? I think this makes the skew look a lot worse than what it really is.

In my case i have found the top of the left margin and the top of the bottom left margin is only 1 mm in difference from the left edge of the paper - which is almost impossible to notice to the naked eye however because the image is trapezoid, the image looks all warped.

i'm currently asking tech support on what is causing this trapezoid image? Surely it cant be a printhead out of position?
