When 2 products come too close together, your controller says “Got another product at PD before product distance  passed. Check photoeye or product distance
That’s fine and you do not print on the product but can’t you open the gate, I don’t want blank products going to my customer.
By setting the product to product distance to 200, the controller will signal an error if the next product comes less than 90% of the product distance, also, it disregards the product. So, yes, it is a blank product on the conveyor.
Since the product is very close to product 2, what we are going to do is divert both product 2 and the blank product.
Go to d:/editorgt/user/system/arguments.txt and go to the box line
box –mingap 130
That will do that the controller will divert product 2 and the blank product if the gap is below 130% of the product length declared in product detect 1..
