...one other thing to note is that the metal curved plate seen off to the left (actually it's a base plate) is the same texture as the four squares...
The easiest solution would be to make it darker in color...so that it almost blends in to the background (and is thereby differentiated from what we see of it within the "printer tray". But I would definitely agree that it looks odd. It always stood out to me as just a bunch of crap that was thrown down to achieve the look of the gadget they needed for the shot. Either that or the props guy hadn't finished working on the piece and they asked for it on set.
