Your POS terminal uses a thermal printer. When the print head is heated to a certain level, printing is made on
thermal paper.

In Case of Power Failure
Even when power is lost, your POS terminal retains its
memory contents and all information on sales entries.
•When a power failure occurs while your POS terminal is
idling or during an entry operation, it returns to the normal
state after power recovery.
• When a power failure occurs during a printing cycle, the
terminal prints “= = = = = = = = = = =” and then carries out
the correct printing procedure after power recovery. (See
the sample print.)

In Case of a Printer Error
If the printer runs out of paper, the printer will stall, and the “PAPER EMPTY” message will appear on the display.
Any key entries will not be accepted. Referring to “Installing and Removing a Paper Roll” in this chapter, install a
new paper roll properly, then press the
CL
key. The printer will print the power failure symbol and resume printing.
If the print head is in the “up” position, the printer will stalls, and the “HEAD UP” message will appear on the
display. Any key entries will not be accepted. Bring back the print head to the correct position, then press the
CL
key. The printer will print the power failure symbol and resume printing.
Thermal Printing
• If your POS terminal 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.
