by the rollers located under the paper pressure unit.
This can occur when the print mode is set to "Stop at Cut Position"
or "Stop at Peel-Off Position", and printed labels have not been
removed after each print job is finished.
Select a print mode option other than "Stop at Cut Position" or
"Stop at Peel-Off Position", or remove printed labels after each
print job is finished.
