When to replace paper
Whenever the printer gives paper out signal or a red line
appears on the thermal paper, it is the proper timing for replacing
the paper. Do not wait till the print engine is dragging the paper
roll at the very end. Remove the leftover and replace a new paper
roll as illustrated above to prevent excessive paper dust in the
printer and consequently possibility for paper jam.
