Overview
Details
Issue
The pen tray lights remain lit when you aren’t using a pen or eraser.
Symptoms
Cause
If the infrared light sensors in the bottom of your pen tray’s recesses are obstructed, the sensors don't detect when a pen or eraser is in the tray, which causes the pen tray to stay lit.
Solution
Clean the pen tray sensors to resolve this issue.

To clean the pen tray sensors
  1. Remove any obstructions from the pen tray’s infrared light sensors.
  2. Moisten a cotton swab with a household glass cleaner and carefully wipe the sensors.
  3. Optionally, spray compressed air over the sensors to remove debris.
If the lights remain lit after you’ve cleaned the sensors, you might need to replace the pen tray.
