6.1 Cutter error troubleshooting

When cutter fails to recover due to paper jam or sudden off-line status, the top cover cannot be uplifted
for the cutter sliding blade is pinned. At this time, you mustn't uplift the top cover by force, otherwise
the cutter will be damaged and the printer will not be able to work normally.
Perform the following actions:
1) Turn off power of the printer;
2) Put your hands on both sides of the cutter top cover and pull it out according to the arrows in the
figure below to expose the manual knob on the cutter sliding blade;
3) Rotate the white knob according to the arrows in the figure below, observe the action of the
cutter from the paper path; Wait until the cutter sliding blade completely deviates from the still
blade, open the top cover and clear paper jam.
Notice 1: When revolving the thumb wheel, the cutter sliding blade acts slowly. Go on revolving
and observe carefully.
Notice 2: If the thumb wheel cannot be turned, do not force the wheel, instead turn it the opposite
direction.
