My interactive pen doesn't work. It lags, skips, or does not write on the projected image. What should I do?
Try the following solutions:
  • The pens turn off automatically if you forget to turn them off. Slide the switch to turn the pen back on.
  • Make sure you are not covering the black section near the tip of the pen.
  • Make sure nothing is blocking the signal between the pen and the interactive pen receiver on the projector.
  • Try holding the pen at a different angle so that your hand is not blocking the signal.
  • Make sure the cable cover is in place to keep cables from blocking the signal.
  • Make sure the pen battery has enough power. Try replacing the battery.
  • If you are projecting from a computer, make sure the USB cable is connected to the computer and projector.
  • Dim the room lights and turn off any fluorescent lights. Make sure the projection surface and pen receiver are not in direct sunlight or other sources of bright light.
  • If the pen tip is worn out or damaged, you may need to replace it.
  • Make sure the pen receiver on the projector is clean and free from dust.
  • Make sure there is no interference from the infrared remote controls or microphones.
  • Make sure the USB TypeB option on the Extended menu is set to Easy Interactive Function or USB Display/Easy Interactive Function.
  • Make sure you have calibrated the system. Try recalibrating.
