Troubleshooting

This chapter contains information about troubleshooting problems that might occur while operating the NCR 7879. Many problems can be corrected locally, restoring the NCR 7879 back to service quickly. Other problems require the aid of a factory trained technician.

Troubleshooting Charts are used that are designed for locating and correcting certain problems without the aid of a trained technician. If the problem cannot be corrected using these charts, a trained technician can use special functions within Scan Doctor to help identify a faulty component.

Note:  Troubleshooting information is also available on a Smart Phone by scanning the QR Code located below the Top Plate on the NCR 7879.
