Gain M
Note: ensure the lens unit is fastened to the camera unit with adhesive (Loctite 425).
Note: When attaching the camera unit to the installation bracket, tighten the bolts with
0.38N.m to 0.57N.m force, and apply adhesive (Loctite222) to the bolts.
Camera focus
Jig: Plate jig (AJPJ-0060).
Jig: Color sample disc for brightness measurement (brightness value of 130).
1. Clamp the Plate jig in the main table.
2. Temporarily remove the lighting unit.
3. Remove the mark camera lens cover.
4. Reattach the lighting unit making sure it is pushed right up against the lip of the
camera installation bracket.
5. Install the mark camera in the machine and set the height of the camera so that the
clearance between the bottom of the lighting unit and the plate jig is greater than 61
mm (61.5mm is ideal). This is to ensure that there is sufficient clearance between
the lighting unit and the nozzle change platform.
