16-4. Check Pen Touch Accuracy
1)
Adjust the angle of the machine and place it in horizontal orientation.
2)
Press [TP Accuracy Check] button on Service Tool Launcher.
Gray-colored cross appears on the screen with red and blue parallel lines on center.
Touch the center of the cross using exclusive touch pen and see whether the deviation of touch position is within an allowance.
Due to the gap between tip of the pen and LCD panel (including glass layer and air space), the actual touch position and the position where
the human eyes recognized touched may differ. Therefore, the deviation toward X-axis and Y-axis should be checked respectively.
