Autocutter Module
This printer is equipped with an autocutter module for cutting of the roll paper
and a manual cutter for manual cutting.
The autocutter has two opposing cutter blades that operate like a scissors to cut the
paper. It is a separate cutter blade-type mechanism that does not require passage of the
roll paper through an autocutter mechanism slit. Opening the frame cover causes the
stationary blade to separate completely from the moving blade. The stationary blade is
fixed to the frame cover, while the moving blade is attached to the main frame.
Autocutter operation
The frame cover can be closed while the movable blade is in the home position.
Closing the frame cover causes the stationary blade to come into partial contact
with the paper cutter frame, and the stationary blade and movable blade are
brought into relative position.
Cutter blade knob
The movable blade is in the home position whenever cutter operation is not being
performed. In addition to safety considerations, this enables a mechanism in which the
frame cover cannot be opened or closed while the movable blade is not in the home
position.
