3.4.6 Adjusting the head gap
If the set screws securing the head gap adjustment plate to the printer frame are loosened or removed, the
head gap adjustment will be necessary.
Preparation
1) Remove the upper cover unit and bottom case. (Or, reassemble the printer so that the upper cover
unit and bottom case are to be attached next.)
2) Remove the paper thickness lever spring and the left and right shaft clips, then attach the bottom
case.
3) Loosen the red set screws on both sides of the printer chassis by a half rotation from the fully
tightened position.
4) Set the paper thickness lever to the down position (for thick paper).
Before doing the adjustment, make sure the gap gauge is not deformed and that no foreign
matter is adhering to it or to the platen.
