Y=0) of the H-position standard plate t.

Note: When adjusting the X home position, be sure to set the clearance between the X-home position dog !0 and the
surface where the sensor !1 is activated to 0.1 - 0.5 mm. If the clearance is too great, an error in home position
detection may occur because the temperature of the sewing machine rises during sewing operation.
