Print line adjust
To have good print quality in hardness or thicker media, we will suggest to move the print line a little bit forward (paper feeding
direction). Turn the flat screw driver (as above figure) in clockwise or counter clockwise to rotate the screws (A) to move back or
forward the TPH position. The adjustment screw (A) of the left and right side of the print head position adjustment should be
adjusted so that the print line is parallel to the center line of the roller. Adjust the screw (A) to rotate one turn, the print head
displacement stroke is 0.5mm, it is recommended to adjust the way progressive, each time to adjust the 1/4 turn to confirm the
print quality situation. (A) Turn the adjustment screw (A) on the left and right sides to the position where the adjustment line is
aligned with the indicating line, and return to the original position and then adjust it again according to the above adjustment
method.
