Chapter5 Troubleshooting Cannot Print 321 Status Cause Solution Auto Paper Feeding does Not Start The sensor has failed. If operation was normal up until now, the sensor has probably failed. Request repairs. The position of the gap detector is not correct. Check the position of the gap detector. U "Adjusting the Gap Detector" on page 294 The printer cannot detect the paper properly. If you are using special paper, the paper may not be fed into the printer automatically. Feed the paper manually. U "Feeding Paper into the Printer Manually" on page 78 Unstable paper detection performance “Unstable” means that: • Print start position is inconsistent.
• Some labels are skipped without being printed • When paper is loaded, the paper is fed more than necessary, resulting in an error. • A paper size error occurs even though the correct paper size is set The gap detector may be incorrectly positioned. Make sure that the light-receiving detector tab and the light- emitting detector tab are in the same position, then calibrate the detector. How to align the gap detectors: U "Adjusting the Gap Detector" on page 294 How to calibrate the detector: U "Adjusting Detectors Sensitivity and Label Detection Thresholds" on page 293 The edge guide is not set along the paper edge. Check that the edge guide is properly set at the paper width position.
When paper is loaded, the paper is fed more than necessary, resulting in an error. Paper Form: Full-page label (without black marks) The paper being used differs from that of Media detection settings. Check the paper being used and Media detection settings of the printer.
