6.1.1. Transmit Mechanism
The Transmit Mechanism consists of components which feed, scan and eject documents, as well as send signals. These
components and their functions are as follows:
ADF Mechanism
The ADF (Automatic Document Feeder) automatically feeds paper into the unit, and consists of the Pre-Feed Roller, ADF Roller
and Separation Rubber. Each document is placed face-down on the Paper Guide Cover before being fed into the unit.
• The Pre-Feed Roller (325) moves the bottom document to the ADF Roller.
• The ADF Roller (323) feeds individual pages into the scanning area.
• The Separation Rubber (229) separates documents placed on the Paper Guide Cover, preventing multiple feeding.
LED Array Assembly
The DX-2000 has two LED Arrays, used as a light source to illuminate the document. The LED Array(s) turns ON when the
Read Point Sensor is activated by the document leading edge.
Transmit Guide Unit
The Transmit Guide Unit is an auxiliary part used for feeding and ejecting documents. It consists of the Control Panel Chassis
(216), Transmitter Chassis (301), Feed Roller (328), Eject Roller (330), and Pinch Roller (218). This unit also provides the white
scanning area and serves as a base for electronic white reference.
