Procedure for Bad Mark Sensor Adjustment
Notice
Do not change the dip switch settings.
Procedure
(1) Change to the current pattern program (the program for current production)
and perform the setup operation.
(2) Put a bad mark on the PCB to be produced.
Note
(a) Use a black mark as a bad mark for a comparatively bright PCB detection
area (PCB with a lot of light reflex).
Use a white mark as a bad mark for a comparatively dark PCB detection
area (PCB with a little light reflex).
(b) When the selection is changed (from "Black Mark" to "White Mark" or
vice versa), be sure to change the mark image ("Black (E/NR)" or "White
(E/R)" in the related "Mark Image" text box of the pattern program data.
(3) Transfer the PCB to be produced to the PCB positioning section.

8. Procedure for Bad Mark Sensor Adjustment
(4) Open the "BAD MARK" window in the "Ship. Adj." window in the "Maint."
menu.
F13
(5) Select the head for which the sensitivity should be adjusted with the related
head selection button.
(6) The "Placement Reference" is the same as that for the pattern program set as
the current program.
(7) Confirm the PEC (PCB) size "X" and "Y" in the "Specified [mm]" data
boxes.
(8) Enter the parameters for the white bad mark position in the "Pos X [mm]"
and "Pos Y [mm]" text boxes for the "Bad Mark Det Pos (White Part)".
(9) Enter the parameters for the black bad mark position in the position "Pos
X [mm]" and "Pos Y [mm]" text boxes for the "Bad Mark Det Pos (Black
Part)".

(10) Press the [Bad mark detection pos. move (White Part)] button and press the
[START] button on the operation panel.
(The head will move to the bad mark detection position (white part)).
(11) Press the [Sens regulation] button.
(12) Press the cover lock switch and open the transparent covers on the upper
section of the beam.
(13) Confirm that the tuning indicator LED (yellow) of the amplifier is ON.
(14) Close the cover and press the Cover Lock switch.
(15) Press the [Bad mark detection pos. move (Black Part)] button and press the
[START] button on the operation panel.
(The head will move to the bad mark detection position (black section)).
(16) Press the newly selectable [Sens regulation] button.
(17) Use several PCBs to be produced to check if the bad mark sensor works
normally.
