Use a blank piece of A3 paper to make an original like the one shown below.
- The line should be 20 mm (0.8 in.) from the leading edge and centered.
- Copy the original.
- Measure the distances from the end points of the line and the edges of the paper.
- The distances should be the same 0±2mm (0±0.1 in.).
If the distances do not match, adjust the position of the ADF. - At the right hinge, loosen the fixing screw [A] and then shift it to the long hole [B].
