5.3.4 Trailing Edge has no enough coating or flat spot
It means applicator roller disengagement time is too soon. The auto gap
timing needs to be increased by holding whilst pressing the
button briefly when the coater is running. Setting a figure greater, auto gap
disengagement time will be longer.
If the symptom of 5.3.1~5.3.4 cannot be corrected with above,
readjust the gap is necessary.
