3.2.1 Drive Mechanism and Signals

0024-6984

This machine is a document feeder exclusively for stream reading.
This machine uses one motor and two electromagnetic clutches to pick up and feed document sheets.  
This machine uses a release motor to prevent the trailing edge of a document from swaying.

The drive mechanism and signals of this machine are as follows:

F-3-2

[1] ADF driver PCB
[2] Release motor drive signal
[3] Release motor HP detection signal
[4] Document detection signal
[5] Document detection signal
[6] Document detection signal
[7] Pickup/feed motor drive signal
[8] Document detection signal
[9] Document set signal
[10] Pressurization solenoid drive signal
[11] Stamp solenoid drive signal
[12] Last document detection signal
[13] Paper size (width) identification signal 2 
[14] Paper size (width) identification signal 1
[15] Paper size (length) identification signal 2
[16] Paper size (length) identification signal 1
