Move the bad mark sensor to a point above the calibration block. Loosen the SEMS cap bolts (a) at two places
and move the BM lens holder so that the distance between the bottom surface of the bad mark sensor and top
surface of calibration block becomes 22 +0.5/0 mm. When the specified distance is reached, secure the bad
mark sensor with SEMS cap bolts (a).

Move the HMS sensor to a point above the calibration block. Loosen the SEMS cap bolts (a) at four places and
adjust so that the distance between the bottom surface of the height sensor and top surface of calibration block
becomes 40 ±0.2 mm. When the specified distance is reached, secure the height sensor with SEMS cap bolts

1. CENT motor stop signal trigger generation timing
2. IN motor start trigger generating timing (when transporting PWBs from the IN buffer to center buffer)
1. Severe collision of the PWB with the stopper due to insufficient deceleration of PWB. (Solution: Make the value smaller
than 8, which, however, results in further beyond the stopper frame.)
PWB failing to reach the stopper due to excessive deceleration. (Solution: Make the value larger than 8.)
2. Increased PWB transport tact time due to delayed starting of IN motor.
