OPERATOR MAINTENANCE
When power is lost, the machine retains its memory contents and all information on sales entries.
• When power failure is encountered in register idle state or during
an entry, the machine returned to the normal state of 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.)
If the printer runs out of paper, the printer will stall, “PPPPPPPPPP” will appear on the display. Key entries will
not be accepted. Referring to
“
4. Installing and removing the paper roll” in this chapter, install a new roll paper in
the proper position, then press the
c
key. The printer will print the power failure symbol and resume printing.
If the print head comes up, the printer stalls, “H” will appear on the very left of the display. Key entries will not be
accepted. Bring back the print head to the correct position, then press the
c
key. The printer will print the
power failure symbol and resume printing.
Cautions in handling the printer
• If you are not going to use the register for an extended period of time, pull the
print head release lever toward you so that the print head is set apart from
the plate. (head-up position)
• Avoid the environments of dusty and humid place, direct sunlight and iron
powder(a permanent magnet and electromagnet are use in this machine.)
• Use the print head release lever only when necessary.
• Never pull the paper when it is in contact with the print head. First release the
head with the print head release lever, and then remove the paper.
• Never touch the surface of the print head.
• Never touch around the print head and the motor during printing or before they have had sufficient time to cool.
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 places for storage. Avoid direct sunlight.
• The printed text on the paper can discolor under the conditions of exposure 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.
