Asf (Auto Sheet Feeder) - Epson STYLUS COLOR 3000 Service Manual

Operating Principles

ASF (Auto Sheet Feeder)

When the printer is not printing, the PF motor drive disengage mechanism detects the position of the CR unit
and engages the planetary gear so the PF motor drives the LD rollers in the ASF. The LD roller shaft has 2
cams that push down the paper support so the paper surface contacts the LD rollers. The one-way clutch
rotates the LD roller in a specified direction to load paper. Once the paper is loaded, the ASF transmission
gear is disengaged and the paper feed mechanism moves the paper.
