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
