Operation manualⅠ

3.3 When a mark recognition error occurs

1) Select the <CAMERA> key of the HOD to teach the center of the mark.
2) If you perform a teaching operation, you can select the "Prod Restart mode."
Judge the mark condition (its shape and whether it is stained or not) and check to see the mark is
located within the inspection frame, and then select the desired button.
3) Specify the "Prod Restart mode," and press the <START> switch. The system processes the mark
according to the "Prod Restart mode" you specified.
Selection of the "Prod Restart mode" is effective for only a board that is currently
centered.
Therefore, a value of the production program is applied to the next board.
If the conditions of all marks on boards of the current lot change due to lot change, edit
the production program.
