MODEL: A7 Series
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.
