Please reword that so we have some idea of what you are describing.
Yesterday we were forced to make a copies of book to reduce its behalf. The problem is that copiyng a page with reduction of 80 % and in first copies we have the positive results,
OK
turning tha page of book with the same settings and the result is negative. As in reduces in the wrong direction?
Once the **bleep** is cut, What is this refering to, nothing should be cut at all,
the second shifted!!! ????
Book copy has edge erase, it is probably deleting the edge which shifts the image.
Someone as already analyzed this issue???
I was not able to replicate your issue at all, nothing shifted with the following workflow.
