7193 Owner’s Guide Chapter 3: Solving Problems
August 1998 23
No Power to Printer or Power Voltages Incorrect
The power being supplied to the printer is not in the normal range. Check that all
connections are correct. Make sure the power supply is plugged in and that the printer is
on-line.
Contact your NCR authorized service representative if this does not resolve the problem.
Print is Light or Spotty
The printhead may be dirty. Clean it with cotton swabs and rubbing alcohol.
Caution: Do not spray the thermal printhead with household cleaner as this may damage
it and the electronics.
If spotty or light printing problems persist after cleaning the thermal printhead, contact
your NCR authorized service representative.
Note: The thermal printhead does not normally require cleaning if the recommended
paper grades are used. If non-recommended paper has been used for an extended period
of time, cleaning the printhead with alcohol will not be of much benefit. See “Ordering
Thermal Paper” in chapter 1 for recommended paper.
Contacting a Service Representative
For serious problems, such as the ones mentioned in the previous section, contact your
NCR authorized service representative to arrange for a service call.
