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.)
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.
