Paper Feed Mechanism - Epson Stylus Pro 9000 Service Manual

EPSON Stylus Pro 9000

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.
