9. GENERAL MAINTENANCE

9.4 Threshold Setting

For the printer to maintain a constant print position it uses the feed gap 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 jammed errors. To get around
this problem a minimum threshold can be set for the sensor in the following way.

(1) When the [PAUSE] key is released within 3 seconds while printer pauses, the [PAUSE] key is invalid.
(2) When the threshold is programmed, 1.5 sheets of the label should be fed. (If less than 1.5 labels are
fed, the threshold may not be properly programmed. In this case, reprogramming is required.)
(3) When the [PAUSE] key is pressed for 3 seconds or more in a head-up state, the [PAUSE] key is invalid.
(4) During a label feed, an error including the paper end, ribbon end or cutter error is not detected.
