4.1 Basic Constraction Chapter 4 4.1.1 Outline 0011-5773 The ADF is a feeding device used exclusively for stream reading, and its series of operations (original pickup, feeding, delivery) is performed using the drive of the ADF motor (M2001). An original picked from the original placement assembly is controlled so that its movement will match the read start timing of the host machine's contact sensor. Then, the original is moved as far as stream reading position, read by the contact sensor (for collection of analog image data), and sent to the delivery assembly. The ADF has 4 sensors to monitor the state of the original. The names and the functions of the sensors are as follows: T-4-1 Symbol SR2001 SR2002 SR2003 SR2004 Sensor Document set sensor Document edge sensor Registration sensor Separation rear sensor Function Detects the presence/absence of an original in the document set assembly. Detects the paper feed status and triggers scanning. Detects the timing at which the leading edge of an original is made to arch at the ADF registration roller. Detects the paper feed status and triggers pickup of the next original.
