0.01 inches) for a status sheet page on A4/letter paper:
If the gap is not correct, adjust the print position as described in the next few steps.
3. Turn printer power off.
4. Open the right cover and shield plate. (See Chapter 3.)
5. Adjust the image synchronizing adjustment volume (VR201) on the main board (C169 MAIN-B)
so that the gap for the print position of the horizontal line (down from the top edge of the sheet)
becomes 29.6 mm (1.17 inches) .

Turn VR201 counterclockwise to decrease the gap.
