2.2 TEARING PAPER:
The printer’s paper door acts as a tear bar. Pull one edge of the paper
against the tear bar as indicated, then tear down and across against the
tear bar to tear the paper.
Caution: The tear bar may have sharp edges.
Using the tear bar is the only way to tear the paper.
Pulling up and pulling sideways without using the tear bar can
cause a paper jam due to paper misalignment in the
print head mechanism

printer off.
