when i printed single prints 8x12, its comes out perfectly ..but when i print out 3 copies at once , the first 2 copies image came out 2mm narrow ( u'll see 2mm white boarder narrow off left top and bottom right. ) , and then the last copy comes out normal. i did all the neccessery adjustment in the SU mode ( centering mode adjusted and measured correctly, did another set out print pattern comes out perfectly fine with the correct value ) but its still the same. Anyone can HELP? anyhow i can do some adjustment to the lens or hardware? i did check on the cables attached to the top lens board , it was nicely attached.
