Operator Maintenance
In Case of Power Failure
When power is lost, the register retains its memory contents and all information on sales entries.
•When power failure is encountered in register idle state or during an entry, the register returns to the
normal state of operation after power recovery.
•When power failure is encountered during a printing cycle, the register carries out the correct printing
procedure after power recovery.
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. Referring to “Replacing the Paper Roll” in this chapter, install a new paper roll
in the proper position, then press the
L
key. The printer will print the power failure symbol and resume
printing.
If the print roller arm comes up, the printer stalls, and “PAPER EMPTY” will appear on the display. Key
entries will not be accepted. Push down the arm until it is securely locked, then press the
L
key. The

the power failure symbol and resume printing.
