Correcting Scanner Problems

When the RealScan 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 at the front of this document. Although several conditions can be identified, following are the most common.
