■ Multi-purpose Tray Pickup Assembly
● Overview
Paper on the Multi-purpose Tray Pickup Tray of the Multi-purpose Tray Pickup Unit is picked
up by the rotation of the Cassette 1_Multi-purpose Tray Pickup Motor (M05).
The Multi-purpose Tray Pickup Roller is lowered by the rotation of the Cassette 1_Multi-
purpose Tray Pickup Motor. When the Multi-purpose Tray Pickup Roller comes in contact
with the surface of paper, a sheet of paper is picked up by rotation of the Cassette 1_Multi-
purpose Tray Pickup Motor (M05), and is moved to the feed path by the Multi-purpose Tray
Feed Roller and the Multi-purpose Tray Separation Roller. Then, it is moved from the Pre-
registration Roller to the Registration Roller by the rotation of the Pre-registration Motor (M06).
The Multi-purpose Tray Pickup Roller and the Multi-purpose Tray Feed Roller are driven by
the Cassette 1_Multi-purpose Tray Pickup Motor (M05) while the Pre-registration Roller is
moved by the rotation of the Pre-registration Motor (M06).
