Sharp ER-A450 Operator Maintenance, In case of power failure, In case of printer error

OPERATOR MAINTENANCE

1In 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 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.)

2In case of printer error

If the printer runs out of paper, the printer will stall, “PPPPPPPPPP” will appear on the display, and the register will start to continuously produce an intermittent beeping tone. Key entries will not be accepted. Referring to “5. Installing and removing the paper roll” in this chapter, install a new roll paper in the proper position, then press the ckey. 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, and the register will start to continuously produce an intermittent beeping tone. Key entries will not be accepted. Bring back the print head to the correct position, then press the ckey. The printer will print the power failure symbol and resume printing.

3Thermal printing

Your register prints by means of thermal printing. The print head applies heat to thermal paper which is chemically treated to change color when heated to a certain level. This creates the printed text.

Cautions in handling the printer

Printing position

•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.
