OPERATOR MAINTENANCE
1 In Case of Power Failure
When power is lost, the machine retains its memory contents and all information on sales entries.
(Note: Three alkaline batteries must be installed.)
• When power failure is encountered in register idle state or during an entry, the
machine returns to normal operation after power recovery.
• When 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.)
2 In Case of Printer Error
If the printer runs out of paper, the printer will stall, and “ ” will appear on the display. Key entries
will not be accepted. Refer to section 5 in this chapter, install a new roll, then press the l key. The printer will
print the power failure symbol and resume printing.
3 Cautions in Handling the Printer and Recording Paper
■
Cautions in handling the printer
• Avoid dusty and humid environments, direct sunlight and iron powder. (A permanent magnet and 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.
• Never touch the surface of the printer head and print roller.
■
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.
