• Remove the cover plate [X] from the sorter adapter (2 screws).

• Install the upper exit guide mylar [Y] on the sorter adapter and fix it

with the cover plate as shown.

NOTE: This mylar is required to prevent some brands of paper, which curl too much after

fusing, from jamming at the sorter stapler entrance area.
The upper exit guide mylar (P/N A3666060) has been enclosed as an accessory in

the machine box from the first mass production.
We will issue an M/B for the upper exit guide mylar later.
