To Prevent and Spreading of Damage
— Never touch the printing head motor, or paper cutting blade. Your finger may
be cut.
— During power-on or immediately after printing, do not touch electrical parts
or moving parts, such as the mechanism, motor, internal dear, etc. They may be
very hot and can burn your hand/finger.
— Be careful to avoid bodily injure or damaging other objects with an edge of
sheet metal.
— Should any error occur while operating the equipment, stop it immediately
and disconnect the power plug from the plug socket.

your hand or finger on the equipment.
— After using the equipment, turn off the power switch and unplug the AC
adapter from a plug socket.
— At the time of maintenance, be sure to turn off the power switch of the printer
and unplug it from the socket.
— Use a dry soft cloth to wipe off stains and dust from the surfaces of the main
body case. For severe soiling, dip the cloth in water and wring it, for wiping
offthe soil. Never use organic solvents, such as alcohol, thinner, trichlene, benzene, ketone, or chemical dusters.
— If the equipment is contaminated with paper powder, use a soft brush
to clean it. Be careful not to damage the printing head.
— Cleaning the Printing Head
1. Referring to “4.5 Removing Paper Jam”, detach the platen roller unit.
2. Moisten gauze slightly with alcohol, and clean the heating surface of the
printing head with it.
3. Reattach the platen roller unit.
The printing head and motor are very hot. Be careful not to touch
them immediately after printing. Do not touch the heating surface
of the head with a bare hand or metal. When detaching or reattaching the platen roller unit, be sure to raise up the printing head,
otherwise, they could be damaged. Handle the detached platen
roller unit carefully so as not to damage it.

Hold the convexity on the rear of the printer cover, and raise it upward.
Cut the front end of the paper roll almost at a right angle.
Make sure that the power is turned on.
Pull the head-up level to this side to raise up the printing head.
5 If there is still some paper remaining after a paper-out indication, eliminate
the paper roll according to “4.8 How to Remove Remaining Paper Roll.”
6 Insert the front end of the paper roll straight into a paper insertion slot.
7 Set the paper roll firmly in the paper holder.
8 Put back the head-up lever. The paper roll is automatically puiied in by the platen
roller to feed a constant amount of paper. (When auto-loading is enabled.)
9 Put back the printer cover.
— The printer cover is not stationary (Opening/Closing). After detaching it,
be careful not to lose or break it
— Do not insert a ragged or dog-eared end of the paper roll, because it could
result in a paper jam or insertion error.
— If the paper roll is still slack, rewind the paper to remove the slack
— If the paper roll is tilted, rais the head-up lever to correct the paper roll
posotion, or pull out the paper roll and set it again.
— Do not open the printer cover while printing.
— Do not hold or press the paper roll while printing, because it could cause a
paper jam.
— After the paper is set, the printer is made ready to start printing. Note that if
data is remaining in the buffer, the printer will start printing after the paper is set.
— Do not run the printer with its cover removed, because it could cause
malfunctioning or an irregularity of the sensor.
