Threshold Setting - TEC B-670 Series Owner's Manual

12. GENERAL MAINTENANCE

12.5 THRESHOLD SETTING

For the printer to maintain a constant print position it 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.
Threshold setting procedure

NOTES:
1. If the [PAUSE] key is released within 3 seconds whilst in pause state, paper will not feed.
2. Failure to feed more than 1.5 to 2 labels may result in an incorrect threshold setting.
3. While the print head is raised, the [PAUSE] key does not work.
4. Error 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 the printer continues to print out of position 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.
