In case of a Power Failure

When power is lost, the machine retains its memory contents and all information on sales entries.
• When a power failure is encountered in register idle state or during an entry,
the machine returns to normal operation after power recovery.
• When a power failure is encountered during a printing cycle, the register prints
"========" and then carries out the correct printing procedure after power
recovery. (See the sample print.)

electromagnet are used in this machine.)
• Never pull the paper when the print roller arm is locked. First lift up the arm, and then remove the paper.

Cautions in handling the recording paper (thermal paper)

• Use only the paper specified by SHARP.
• Do not unpack the thermal paper until you are ready to use it.
• Avoid heat. The paper will color at around 70°C.
• Avoid dusty and humid storage places. Avoid direct sunlight.
• The printed text on the paper can discolor under conditions of high humidity and temperature, exposure to the
direct sunlight, contact with glue, thinner or a freshly copied blueprint, and heat caused by friction from
scratching or other such means.
• Be very careful when handling the thermal paper. If you want to keep a permanent record, copy the printed text
with a photocopier.
