OPERATOR MAINTENANCE

1

In case of Power Failure

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 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 “PAPER EMPTY” will appear on the display. Key entries will not be accepted. Refer to section 4 in this chapter, install a new roll, then press the l key. The printer will print the power failure symbol and resume printing.

If the print head comes up, the printer stalls, “HEAD UP” will appear on the display. Key entries will not be accepted. Bring the print head back to the correct position, then press the l key. The printer will print the power failure symbol and resume printing.

Cautions in Handling the Printer and Recording Paper

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)

Printing position

Head-up position

• Avoid dusty and humid environments, direct sunlight and iron powder

(a permanent magnet and electromagnet are used 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.

70

Cautions in handling the recording paper (thermal paper)

• Use only 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 means.

• Be very careful when handling the thermal paper. If you want to keep a permanent record, copy the printed text with a photocopier.

Replacing the Paper Roll

Be sure to use paper rolls specified by SHARP.

The use of any other paper rolls other than those specified could cause paper jamming, resulting in register malfunction.

Paper specification

Paper width: 1.75 ± 0.02 in (44.5 ± 0.5 mm)

Max. outside diameter: 3.15 in (80 mm)

Quality: Thermal paper

• Be sure to set paper roll(s) prior to using your machine, otherwise it may cause a malfunction.

Install the paper roll in the printer. Be careful to set the roll and cut the paper end correctly.

If the top end of the paper roll is fixed with paste or tape, the paper may lose its color development ability in the pasted or taped area due to the deterioration of the heat-sensitive color development component of the paper surface. This may result in nothing appearing at this location when printing. Therefore, when setting a new paper roll in the machine, be sure to cut off approximately one revolution (approx. 25 cm long).
