Problem
What to Do
Where to Go
Receipt paper is low*
There are about 4 ½ meters,
±
3 meters, (15
feet,
±
10 feet) of paper left. Change the paper
soon to avoid running out of paper part way
through a transaction.
See “Loading and
Changing the Receipt
Paper” in chapter 2.
Thermal printhead temperature
is out of range
The printhead may overheat when printing in
a room where the temperature is above the
recommended operating temperature or when
printing high density graphics continuously,
regardless of the room temperature. In either
case, the printer will shut off.
If the temperature of the printhead is too hot,
adjust the room temperature or move the
printer to a cooler location.
See “Environmental
Conditions” in Appendix
A for the recommended
temperature range for
operating the printer.
If the printhead is overheating because of
printing high density graphics continuously,
reduce the demand on the printer.
If the printer continues to overheat, contact a
service representative.
See “Contacting a Service
Representative” later in
this chapter.
Power supply voltage is out of
range
If paper is not low and no conditions indicate
that the printhead is too hot, the power supply
voltage is out of range. Contact a service
representative.
See “Contacting a Service
Representative” later in
this chapter.
Red LED Is Constant
Problem
What to Do
Where to Go
Receipt paper is out
Change the paper now. Do not run a
transaction without paper as the data may be
lost.
See “Loading and
Changing the Receipt
Paper” in chapter 2.
Receipt cover or front cover is
open
Close the cover. The printer will not operate
with either of the covers open.
Knife failure
Open the receipt cover and check the knife.
Clear any jammed paper you can see. Tear off
any excess paper against the tear-off blade.
Contact a service representative if this does
not resolve the problem.
See “Contacting a Service
Representative” later in
this chapter.
