Chapter 3: Solving Problems
Correcting Problems
Operator-Correctable Conditions
The following conditions can be corrected generally without calling for service. However,
if problems persist, contact your NCR authorized service representative to arrange for a
service call.
Paper Out
Replace the paper roll. Do not operate the printer or host computer if the printer runs out
of paper. The printer will not operate without paper, but it may continue to accept data
from the host computer. Because the printer cannot print any transactions, the data may be
lost.
See "Loading and Changing Paper" in chapter 2 for more information.
Knife Failure or Paper Jam
A problem or jam has occurred with the knife. Open the receipt cover and visually inspect
the knife inside the cover. Clear any jammed paper you can see. Tear off any excess paper
against the tear off blade.
Contact your NCR authorized service representative if this does not resolve the problem.
Receipt Cover Open
Check that the receipt cover is completely closed. You can tell if it is not closed properly if
it swings open easily. When closed properly, it requires some exertion to open because of
the snug fit.
Service-Related Problems
The following problems may require you to contact your NCR authorized service
representative to correct the problem.
Print Head Over/Under Temperature
There is a problem with the temperature of the printhead. It must remain within a certain
temperature range to operate properly. This problem will most often occur when the
printhead overheats rather than running under temperature.
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. In either case, the printer will shut off. See "Appendix A: Specifications" for
information on the recommended temperature range for operating the printer and on the
restrictions of printing high density graphics continuously.
If the operating temperature is too hot, adjust the room temperature or move the printer to
a cooler location. If the printhead is overheating because of printing graphics continuously,
reduce the demand on the printer.
If the printer continues to overheat, contact your NCR authorized service representative.
