Specify the write start position (printing start position) as described below:
(i) Measure the length of the write position.
(ii) Measure the inter-character distance (C).

3.3.1-6 Sensor filter
Perform this setting when operation shall be continued normally even if chattering
occurs.
In the case that a printing target detection signal chatters, the time to ignore the
sensor filter is set.
When a fault caused by chattering occurs, the message "Print Overlap Error"
will be displayed.
If the sensor filter feature is not needed, set the value to 0.
The value can be set from 0 to 9999 milliseconds.
The options "time setup" and "until end of print." are available.
