Power indicator light is ON but screen is OFF
If you are unable to see anything displayed on the screen, we can rule out a problem with the touchscreen’s brightness by dimming any local light sources and making sure that the brightness slider has an appropriate setting. If you are still unable to see anything on the touchscreen and you’ve confirmed that the unit is appropriately powered on, please contact customer support for further assistance.
Tapping and pressing of keys on the keyboard display is misaligned – for example, tap a letter and the letter next to it is pressed instead
Please try turning the scanner off, unplugging the power cord and waiting 30 seconds. When you turn the scanner back on, the touchscreen should respond properly. If it does not, repeat the process, and try using a stylus or pen cap to interact with the screen. If the problem persists after this, please contact customer support for further assistance.
