15 Operator Maintenance In Case of Power Failure When power is lost, the POS terminal retains its memory contents and all information on sales entries. • When power failure is encountered while the POS terminal is at an idle state or during an entry, the POS terminal returns to the normal state of 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.) Power failure symbol Print after power recovery In Case of Printer Error If the printer's motor happens to lock, the printing stalls and intermittent bleeping starts. You must, first of all, cut the power supply and repair the paper jam. Then, when the cord is plugged into a receptacle, message "PRINTER ERR" is displayed. Feed the roll paper to the proper position and depress the CL key. The register carries out the power failure symbol and continues printing. Paper roll near-end sensing function (only for journal paper) When the journal paper roll comes near the end or is not loaded, the machine senses this condition and sounds an alarm, displaying the error message "PAPER EMPTY". At this time, clear the alarm with the CL key and replace the paper roll as soon as possible. The following entry can be made after clearing the alarm. However, since this function works each time one transaction is completed, the alarm sound will be emitted again as the following transaction is completed unless the paper roll is replaced. If you want to use this function, consult your dealer. • The sensing position depends upon the size of the paper tube. Therefore, it is advisable to use paper rolls - whose paper tube is 18 mm in O.D. and 12 mm in I.D. - specified by SHARP. • If sensing occurs too early or late, contact your dealer.
