Caution!
・The position of the collator’s rubber legs will be deviated from
the round slot for setting the rubber legs on the machine table.
・In case two connected collators are used, place UC-1100L (Left
tower) in the position shown on the drawing on the right and place UC-1100 (Right tower) in the normal position (round
dent on the cover panel of the collator table).
1.3 Confirmation of contents and attachments
After unpacking the collator, check the attachments. Should any part be missing, contact your dealer immediately.

4.2 Installation and dismantling of forceful ejector
(1) Switch the stacking switch lever to the connection side.
(2) Firmly hook the pins (one black pin each on right and left sides) set at the lower part of the collator on the hook on the forceful ejector (on the stacker side).
(3) Put the round holes (12mm in diameter on both sides) of the forceful ejector over the pins (two plated) on the slide plate cover.
Caution!
Fit the holes into the pins while moving the stacker from side to side.
(4) Of two connectors of the forceful ejector, insert the black one in the black plug on the stacker, and the other metal one in the metal plug on the collator (on its back side), and insert the power cord into the plug of collator.
