General problems
The lights on the control panel do not come on.
Make sure that the power supply cables are correctly plugged into
the printer, the power unit, and to the power outlet.
Make sure that power is supplied to the power outlet. If the outlet
is controlled by a switch or timer, use another outlet.
Printing problems
The

light is on (not blinking) and nothing is printed.
If the
RECEIPT OUT
or
JOURNAL OUT
light is
on
, a paper roll is not
installed or is at or near the end. Install a new paper roll. See
Chapter 1 for instructions.
