Thought you’d be interested in this. This is what I was trying to say in my first comment that these documents have markings to align the page for optical character recognition (OCR)
A big problem is people are lazy and when scanning documents they don’t properly align the page on the scanner. So, if the document has them, the software looks for these markings so it can digitally realign the page so that the zones you want to read are positioned correctly.
