Wait LED blinking - Self-Adjustment required but not possible
If the Wait LED blinks (and the Diagnostics LED is off) the scanner needs to run Self-Adjustment but cannot. Self-
Adjustment is necessary for maintaining optimal and stabile internal conditions.
To solve this, any original in the scanner should be removed, and the pressure-platen should be set to the Normal
position (i.e., not a thick media setting). A scan may be issued, but the quality will be compromised. When Self-
Adjustment is again possible, the Wait LED stops blinking, but continues to be on until Self-Adjustment is
completed. The scanner should be left alone while Self-adjustment is running.
During Calibration – Wait LED lights
This is normal. The Wait LED is on during Calibration to indicate that the original should not be removed or moved
during the Calibration procedure.
All panel input is prevented during basic calibration.
Diagnostics LED blinking – Error detected during Self-Test
The Diagnostics LED shows the scanner's Self-Test result status. An unlit Diagnostics LED means that the
scanner's Self-Test procedures encountered no errors.
If the Diagnostics LED blinks, an error was discovered during Self-Test. Open WIDEsystem (double-click the
scanner icon on your system tray) and select the Status tab to view additional information about the error.
Both Diagnostic LED and Wait LED blinking – Maintenance needed
Simultaneous blinking by both the Diagnostic LED and the Wait LED may mean that the scanning area needs
cleaning and the cameras calibrated. See the section on "Maintenance" for instructions.
If the Diagnostic and the Wait LEDs continue to blink after scanner maintenance, there may be camera position
errors that require professional technical service.
