SPECIFICATIONS AND OPERATION
5. Sensor Adjustment
There are three different sensors: the transmissive sensor (label start-position detector), the black-mark sensor, and the
paper-out sensor. Adjustment procedures are described below. First note the following general points.
• The transmissive sensor level requires precise setting. Because transmission rates vary widely among different
types of label paper, we recommend that the sensor be readjusted each time the user changes to a different paper
type.
• Because black marks are likely to be similar across different paper types, the black-mark reflective sensor may
not require readjustment each time the paper type is changed. But you will still have to adjust it if the new paper
has a different consistency or uses a different black-mark density, or if the paper-feed routing is changed.
• In most generally not necessary to adjust the paper-out sensor.
