Label Gap Sensor
Adjustment
The EasyCoder PC4 printer is fitted with a label gap sensor that detects
slots between tickets and tags, or gaps between labels, as the media is fed
past the sensor during printing. Thus the firmware can determine the
length of the tags or labels and control the media/ribbon feed accord-
ingly.
The label gap sensor is a center-aligned photoelectric sensor that mea-
sures the light that passes through the media path. The transparency of
the liner of a label supply may differ between batches, making it difficult
for the sensor to discriminate between labels and liner. When this occurs,
the indicator lamp will switch from green to orange, indicating that
sensor should be adjusted by entering the Test Mode, as described below.
