Failure Modes
One Razzberry Tone
This indicates that the scanner has experienced a laser subsystem failure. The scanner will try up to three
times to correct the failure condition. If the laser subsystem continues to fail, that subsystem (horizontal or
vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This error
stays on the display until corrected. If the remaining subsystem is still operational, scanning will continue using
the operational components.
Two Razzberry Tones
This indicates that the scanner has experienced a motor subsystem failure. The scanner will try up to three
times to correct the failure condition. If the motor subsystem continues to fail, that subsystem (horizontal or
vertical) will be shut down and an error indication will be shown on the Diagnostic Indicator Display. This error
stays on the display until corrected. If the remaining subsystem is still operational, scanning will continue using
the still operational components.
Continuous Razzberry Tone with Blue LED Off
If, upon power up, the scanner emits a continuous razzberry tone, then the scanner has an electronic failure.
Return the unit for repair at an authorized service center.
Three Beeps - On Power Up
If the scanner beeps three times on power up then, the nonvolatile memory that holds the scanner
configuration has failed. Return the unit for repair at an authorized service center.
