My pen doesn't work. It lags, skips, or does not write on the projected image. What should I do?

• Try the following:
  • Make sure nothing is blocking the signal between the pen and the interactive pen receiver on the projector. See Projector Parts.
  • Make sure the cable cover is in place to keep cables from blocking the signal.
  • Make sure the pen batteries have enough power. If the light on the pen doesn't turn green when you press the button, you need to replace the batteries.
  • Dim the room lights and turn off any fluorescent lights. Make sure the projection surface and the pen receiver are not in direct sunlight or other sources of bright lighting.
  • Make sure the pen receiver on the projector is clean and free from dust.
  • Make sure there is no interference from infrared devices (e.g., infrared remote controls, infrared microphones, infrared mice, etc.).
  • Make sure the location is free from electromagnetic interference from nearby equipment (such as electric motors or transformers).
  • Make sure the USB cable is securely connected to the projector and computer. Try disconnecting and reconnecting the cable to your computer.
  • Epson recommends using a VGA connection to project your computer's image when using the interactive pens. Using other types of connections to project your image, such as USB Display or a wireless connection, may cause your pens to not work properly (e.g., the pens may lag or skip). Check the following when projecting using a VGA connection:
    • Make sure your computer is connected to the projector's Computer 1 or Computer 2 port. See Connecting to the VGA Computer Port.
    • Make sure a USB cable is securely connected between your computer and the projector. See Connecting the USB Cable for the Interactive Pens or Remote Mouse Control.
      
      Note:
      Connecting to a USB 2.0 port on your computer or laptop is recommended for the best interactive performance.
    • Make sure the USB Type B setting in the Extended menu is set to Off. See Customizing Power and Operation.
    • Make sure you selected Computer for the image source. See Selecting an Image Source.
  • If the tablet function does not work, you may have other tablet device drivers on your system. Uninstall the Easy Interactive Virtual Tablet Driver using the Windows Control Panel.
  • If you're using a USB hub, connect the projector directly to your computer.
  • You may need to recalibrate. See Calibrating the Projector.
  • Try updating your computer's video driver.
  • In Windows XP, open your operating system's Display utility. Click the Settings tab, then click Advanced. Click the Troubleshoot tab, and set Hardware acceleration to None.
  • If the  pen icon has a red X on it, try restarting the Easy Interactive Driver.
  • Try using a different pen.
