When a Nextimage software key does not work, it is typically only for one of two reasons.

a.) Please ensure you are logged into the PC as the Local Administrator when entering the key.

b.) Nextimage keys are specific to the version of software you own. For example, a Nextimage version 1 key will not work with version 4 software.

The solution is to downgrade back to Nextimage version 1.x or purchase a new updated software key.

Vertical lines in your image are typically caused by dirt or scratches on the glass plate. Please clean the glass to remove the streaks. Please see your Scanner User’s Guide for more information in dealing with this problem.

Note: Dirt present on the glass plate during calibration will be memorized by the scanner and may later show up as bright colorless vertical lines in the image. Such lines cannot be removed by cleaning the glass plate alone. Therefore you must perform both cleaning and then re-run calibration in WIDEsystem as well.
