Ryobi 2800 with T-head registration

[jimas67]

Hi All,
I'm hoping someone can help with a small problem, on our Ryobi 2800 when trying to line up with the T-head, on a 81/2 X 11 sheet of stock I can get the middle targets to line up but my top and bottom will not. If targeting the press on an 11 X 17 sheet I can get the targets to hit on the top, middle and bottom. Would packing one or the other help on a short sheet?

if you put a sheet of 20lb bond behind the plate on the t-head, back off the impression to account for it, you will "shorten" the image by about 1/32" over the 11" length. i had an itek 960 that had crashed running envelopes that did this same thing. turned out the impression cylinder was slightly dented near the gripper edge.
