(1) Print head gap adjustment
When replacing the carriage unit or platen, check that the gap between the print head and platen is 0.38 ± 0.03
mm at both ends of the platen. To check the gap along the platen, use a platen gap adjustment gauge and move
the carriage to the left and right. To adjust the gap, turn the two levers at the ends of the stay shaft.
