2.5.6 When the head gap needs adjustment
The head gap needs to be adjusted when the screws fixing the head gap adjustment
boards to the printer frame have been removed or loosened.
Preparing for the Adjustment
1) Remove the upper cover unit and the bottom case. (Or, assemble the upper cover
unit and the bottom case to the point they are ready to be installed)
2) Remove the paper selector lever spring and the shaft clips on the left and right, and
reinstall the bottom case.
3) Loosen the red fixing screws on both sides of the printer chassis by a half-turn
from the fixed position.
4) Lower the paper selector lever to the thick paper position.
Make sure that the gap gauge is not deformed and no foreign matter is
attached to the gap gauge or the platen before performing the adjustment.
