C75 CHALLENGE.... this IS the correct code. what is it? 091-317 and 091-603

[djwhoo]

091-317 and 091-603 does not exist in the book?

We have perfect stripes only on black out side the image area on the transfer belt and always only showing up on the edge when you have a big stack.only from the black drum not colors.
what are these codes?

I hope someone can dig deep for an answer..
