The print does not start at the top laser dot, but approx. 3-4 cm to the left of it.
To find the starting point, mark the upper laser dot with a pen on a piece of tape on the wall. Then print a rectangular image and measure the distance between the edge of the image and the dot on the tape.
Please note that each pass mode has a different starting point! However if it is measured once, it will not change.
