PAPER FEED MECHANISM

The EPSON Stylus Pro 7000 feeds roll paper and cut-sheet paper using friction, and the two sensors along the paper feed path provide all necessary information for controlling the paper feed process. The sensors are the P-Rear sensor located on the right near the top of the paper feed path and the P-Front sensor located on the right under the carriage path. See Figure 2-12, "Paper Feed Sensors" on page 64. Another important point to remember about the paper-feed mechanism is the paper suction fans.

The paper suction fans are located behind the lower paper guide and are necessary to keep the roll paper flat against the lower paper guide, which prevents ink smears. The fans create a vacuum through the holes in the lower paper guide, pulling the paper flat against the guide. The strength of the vacuum is adjusted according to the media type setting.
