so i am doing the manual slant adjustment with the screws and get the test draw to show the magneta and cyan lining up vertically and from what i can tell on top of each others dots. however, to the sides of the slant test draw strip to the right the magenta staggers off and the cyan staggers off to the left. only 1 head does this, the other looks perfect. i can not correct this with the adjustment screws. could the head not be sitting flush on the carriage? im at a loss here.
