When writing with two pens, the pens skip and break up. What is wrong?

• If the pens are causing interference or unwanted effects, try the following solutions:
  • When both pens are used at the same time, make sure they are approximately 4 inches (10.16 cm) apart.
  • Do not rest the pens on the image area of an interactive table, to avoid interference with your computer's mouse.
  • Make sure that nothing is blocking the direct line to the infrared site.

  Solutions When the Interactive Pens Are Slow or Difficult to Use

  If the pens are difficult to use or respond too slowly, try the following solutions:

  • For easier operation, hold the pen perpendicular to the projection surface.
  • For the best performance, connect your computer to the projector using a VGA or HDMI cable for display and the USB cable for interactivity.
  • If you are using USB display in Windows, you may need to disable Windows Aero in the Epson USB Display Settings program on your computer.
  • If you are having difficulty double-clicking in Mac OS X, go to the Preferences menu, select the Mouse Tracking Speed option and reduce the double-click speed.
  • If you are projecting over a network, see the EasyMP Network Projection Operation Guide for performance adjustment instructions.

  Solutions When the Interactive Pen Position Is Not Accurate

  If the pen position is not the same as the mouse pointer, try the following solutions:

  • Make sure you have calibrated the system. Try manual calibration.
  • Make sure the cable cover is in place to keep cables from blocking the signal.
  • Try adjusting the pen operation area.
  • If you use the E-Zoom + button on the remote control to enlarge the image, the pen position is not accurate. When you return the image to the original size, the position should be correct.
  • In PC Interactive mode (in the Extended menu), turn off Auto Adjust Pen Area and select Manual Adj. Pen Area.
  • Try changing the computer's resolution to 1280 × 800.
