ADF Key Components: MX410/MX51x/MX61x
ADF Key Components Table: MX410/MX51x/MX61x
Component Function
Document Sensor
Determines the first side of the document to be scanned and signals the flatbed Carriage Motor to
move the CCD Imaging Unit to the ADF scan area.
Pickup Roller
Feeds the media into the ADF.
Separator Roller
Counter rotates against the Pickup Roller to keep multiples sheets of paper from feeding.
Stage and Interval
Sensors
Actuating these sensors tells the ADF that this is the first side of the document to be scanned. In
addition, The Stage Sensor determines and corrects skew in the media.
Paper Feed 1 Roller
Acts as a registration roller to correct skew in the media. After a certain count (determined by the
feed motor encoder), the roller rotates and advances the media to the Paper Feed 2 Roller and
Feed Sensor.
Paper Feed 2 Roller
Advances the media to the Scan Area.
Feed Sensor
If the paper does not reach the Feed Sensor before a certain encoder count is attained, a 28x.xx
paper jam error is generated.
Scan Area
The media is scanned by the CCD and image acquisition takes place.
Duplex Sensor
Shines light onto the document (LED).
Eject 2 Roll
On a duplex scan, helps pulls the media back into the ADF toward the Duplex Sensor.
Exit Roller
Pushes the media into the bin. If the job is duplex, the roller reverses and pulls the media back
into the duplex toward the Eject 2 Roll.
