Correcting Scanner Problems
When the NCR 7882 is first turned on, several diagnostic tests are run to check the
status of various components. If a failure occurs, a series of beeps and flashes of the
Green Status Indicator identify it. The number of beeps (flashes) identifies the problem.
The problem indication is repeated continuously with a 3-second pause between each
indication series. Following the first problem indication, the beeps are turned off and
only the Green Status Indicator flashes to identify the problem.
If the diagnostics identify a problem, you must have the scanner repaired. Refer to
Obtaining Technical Assistance on page 3. Although several conditions can be identified,
following are the most common.
