OPERATOR MAINTENANCE
When power is lost, the machine retains its memory contents and all information on sales entries.
• When a power failure is encountered in register idle state or during an entry, the machine 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.)
If the printer runs out of paper, the printer will hault, “PAPER EMPTY” error will appear on the display, and the
register will start to continuously produce an intermittent beeping tone. Key entries will not be accepted.
Referring to
“
4. Installing and removing the paper roll” in this chapter, install a new roll paper in the proper
position, then press the
c
key. The printer will print the power failure symbol and resume printing.
If the print head is up, the printer haults, “HEAD UP” error will appear on the display, and the register will start to
continuously produce an intermittent beeping tone. Key entries will not be accepted. Bring the print head to the
correct position, then press the
c
key. The printer will print the power failure symbol and resume printing.
Your register prints by means of thermal printing. The print head applies heat to thermal paper which is
chemically treated to change color when heated to a certain level. This creates the printed text.
Cautions in handling the printer
• If you are not going to use the register 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.
