Press the [FEED] key
and [RESTART] key at
the same time.
NOTES:
1.
Make sure to adjust the black mark sensor using the white part of the tag paper as
a criterion. Though an adjustment can be performed with the black mark, it may
cause a paper jam error.
2.
Pressing the [PAUSE] key validates the sensor adjustment. The value of the
sensor is displayed up to 5.0 V.
3.
When the difference is less than 1.5 V, used media may be improper (unspecified),
or sensitivity may be dull due to an excessively old or dirty sensor. In this case
change the media to one specified, or replace or clean the sensor. Then re-adjust
the black mark sensor.
6.5 SENSOR SETTING MODE
6.5.2
Black Mark Sensor Adjustment
Black mark sensor setting should be performed after replacing the CPU PC board or changing the
tag paper to another maker’s, or when a paper feed error occurs. The black mark sensor has a
movable and a fixed mode. These are selected by the DIP switch.
After changing the black mark sensor type, follow the procedure below to make an adjustment.
