2.3 Motion check of board flap
The board flap (hereinafter referred to as flap) presses the board along its Y-direction edges to flatten the
upward warp. As the motion error of flap causes printing offset, the flap should be checked periodically if it
operates correctly, and if the flap detection sensor actuates normally.
