When the OUT sensor does not detect a board, the OUT buffer is se
for carriage in possible condition. The chart on the left shows an
error status. But, this error does not always occur when a board
which is short in X direction is placed close to the C.OUT sensor.

NOTE:
Top/bottom line in the box of the table means:
Top: For the nozzle served to only the laser
Bottom: For the nozzle served to the vision and
the laser (vision/laser)
NOTE:
Replacement height differs between the nozzle of KE740 dedicated to the laser
and the vision/lazer nozzle with black urethane rubber. (The vision/lazer
nozzle is higher by 1 mm than the the nozzle dedicated to the lazer.) Nozzle
location No. for the vision/laser nozzle is W, X, Y, and Z.
