Paper Pulling-In, Registration, Feeding And Ejecting Mechanisms - Brother DCP375CW Service Manual

3.2.2.4 Paper pulling-in, registration, feeding and ejecting mechanisms

These mechanisms are driven via a gear train by two motors--paper feed motor located on the
left side of the engine chassis and ASF motor in the right rear corner. (See the illustration on the
next page.)
The following illustration is a cross-sectional view of the machine viewed from the right. Place
the recording paper face down in the paper tray. This paper first proceeds to the rear, bends
upward, heads back toward the front, passes under the head/carriage unit for printing, and
finally comes out onto the top of the paper tray cover.
The machine supports two paper feed modes--"normal SF mode" and "high-speed feed mode."
Depending upon the selected print quality, either of these two modes applies as listed below.
