It is suitable for applications such as checking for dirt on battery surface, scratches on sheets and checking whether LEDs light up properly. Example: Inspection for Dirt on Battery Surface BRIGHT OK OK BRIGHT NG NG due to dirt Section 4 SETTING OF INSPECTION CONDITION Basic Setting Procedure Teaching Enclose the area to be inspected using a rectangular box and then perform teaching.

CHARA1 Select this item to check for presence of the entire character string printed on plain background. Judgment is performed by monitoring changes in density (brightness) of the registered character string. This item is suitable for applications such as detection of presence of prints on chips and presence of entire characters of the best-before date. Example: Detection of presence of prints on chip CHARA1 OK OK 505 Section 4 SETTING OF INSPECTION CONDITION CHARA1 NG NG due to absence of characters 50 50 5 5 50 50 5 5 CHARA2 Select this item to detect omission of single characters. This item is suitable for applications such as detection of missing character in character strings such as the best-before date.

Inspection area setting CHARA1 OK Teaching 50 505 Teaching area for [CHARA] For the teaching area when the printing position is out of position, set to an area in which the character string might possibly be printed out of position. (Be sure, however, to set to an area having a plain background. ) If an area very close to the character string without any margin is set, the sensor will not be able to track any shift in the printing position. Section 4 SETTING OF INSPECTION CONDITION Right 04. 07. 01 OK 04. 07. 01 Any shift of the printing position inside the teaching area is judged as OK. Wrong 04. 07. 01 NG 04. 07. 01 When the teaching area is set very close to the character without any margin, character protrudes from the teaching area and so this is judged as an NG.
