Spray whiteboard or glass cleaner directly onto the marker stain and let it dry.
Wipe off the cleaner with a soft cloth such as an old T-shirt.
Cover the stain with ink from a dry-erase marker if the cleaner does not work.
Wipe off the ink with the cloth while it is still wet.
Select a pen from the tray and insert the tip into the reset button. The button is located on the lower right-hand side of the Smart Board. The ready light should turn green.
Unplug the USB cable if Step 1 is ineffective. Reconnect the cable.
Press the reset button with the tip of a pen from the tray for longer than three seconds. If Step 2 is ineffective, this will prompt you to repeat the orientation of the board.
Restart your computer if Step 3 does not result in a green ready light.
Orient the screen if your writing does not align with the tip of the pen. Begin the process by simultaneously pressing the right-click and keyboard buttons on the pen tray.
Follow the steps to orient the board. Tap the marks on the screen with a pen from the tray rather than your finger so the touch is more accurate.
Test the screen by writing with a pen from the tray when the orientation process is complete. Test the eraser as well.
Adjust the position of the projector if the screen size is accurate but not aligned.
Adjust the zoom setting on the projector if the screen size is too large or too small.
Adjust the focus setting on the projector if the image is blurry. Sometimes the zoom also affects the focus so you may need to adjust both.
