6.4 Threshold Setting

6.4 Threshold Setting

NOTES:

1.If the [PAUSE] key is released within 3 seconds while in pause state, paper will not feed.

2.Failure to feed more than 1.5 labels may result in an incorrect threshold setting.

3.While the Print Head Block is raised, the [PAUSE] key does not work.

4.Errors such as paper end and cutter error are not detected during paper feed.

5.Selecting the Transmissive Sensor(for pre-printed labels) within software commands allows the printer to detect the proper print start position correctly even when using pre-printed labels.

6.If using the transmissive sensor and the printer continues to print out of position even after setting the threshold, adjust the Feed Gap Sensor in the system mode. Reset the threshold again. Make sure that the Transmissive Sensor (for pre-printed labels) is selected in the feed and issue commands.

To maintain a constant print position the printer uses the Transmissive Sensor to detect the gap between labels by measuring the amount of light passing through the media. When the media is pre-printed, the darker (or more dense) inks can interfere with this process causing paper jam errors. To get around this problem a minimum threshold can be set for the sensor in the following way.
