There's what I take to be an earlier version, where the tensioning method is the same as it was for preceeding T models. There's also a simplified version. This post explains the operation of the earlier type, and shows a modification to enhance its reliability. This post gives the teardown procedure for the trays.
In the simplified version, the drawer-actuated tensioning lever has been deleted. The pinch roller is always tensioned; there's no lever to jam and break.
We've seen several of the earlier T64X trays lately with broken tensioning levers. The fault is easy to spot -- the pinch roller (the smaller roller in front) has no tension against the outfeed roller at all; you can see daylight between the rollers. Here's a view inside of what's happened in those cases.
The lever has snapped. The spring has jumped off its hook on the lever. Pinch roller tensioning is completely inoperative -- the tray will not feed.To fix this, first pry the lever remnant off from below with a long, slim-bladed screwdriver. Then get the loose end of the spring hooked over the lever's spindle and tensioning is restored. (Getting the spring end in place is easier said than done, but it is doable. You have to distort the loop at the end of the spring a bit to get it to fit over the spindle. Here's a view of a completed tensioning repair.
