PAPER FEED MECHANISM
The EPSON Stylus Pro 9000 feeds roll paper and cut-sheet paper using
friction-feed, and the sensor along the paper feed path provide all necessary
information for controlling the paper feed process.
 Paper Suction Fan
The Paper Suction Fan is located behind the lower paper guide and sucks
air through the holes in the lower paper guide, pulling the paper flat/even
with the lower paper guide. This helps to keep the paper straight as it is fed
through the printer and prevents ink smears.
