CHAPTER 2. BASIC OPERATION
G. Cutter Unit

1. Outline

The Cutter unit is installed on the carriage.
As the carriage moves, the cutter lowers,
cutting the roll media. The Cutter unit is
moved up and down along the slope of the
platen to prevent cutting failure, and a paper
retainer is provided to cut the paper while
compensating its slackness or unevenness.
To maintain cutting quality, the blade
position can be switched through 5 stages by
turning a dial.
For safety, the Cutter unit is designed not
to be removed from the carriage when the
cutter blade is out.
REFERENCE
Roll media is cut as follows.
• After new roll media is picked up,
80mm is cut to straighten the front
edge.
• After the roll media is printed, the rear
edge is cut.
• When the FORCE CUT function is
executed, the roll media is cut.

2. Cutting operation

When roll media is cut, the carriage
advances to the left side of the platen and the
cutter hook is released by the cutter guide at
the left edge of the guide rail. The cutter is
lowered by its spring.
The carriage cuts the roll media while
returning, and the cutter rises along the cutter
slope on the right side of the guide rail and is
stored there.
