HP digital sender 9200c Manuale Di Servizio

The ADF has built-in duplexing capability for scanning two-sided documents. Pages from the original
document enter the ADF from the ADF input tray. A separation roller and separation pad work
together to separate the top sheet from the stack. The page passes through a set of registration
rollers and two sets of feed rollers that advance the page. A set of delivery rollers delivers the page
to the ADF output bin. A bin-full sensor detects when the ADF output bin is full and stops the feed
mechanism until the bin is emptied.

  ADF paper path and sensors

When the sensors inside the ADF detect a jam, the feed and read motors immediately stop. A signal
is sent to the scanner controller board, which notifies the formatter. An ADF Paper Jam message
appears on the control-panel display.

To clear a jam, open the jam-access cover and remove the media. When sensors do not detect
media after entering the jam state, the jam message is cleared from the control-panel display.

During the initialization sequence or after the ADF jam cover has been opened and closed, if the
registration sensor, read sensor, or exit sensor detects the presence of media, the scanner controller
board determines that a residual-media jam has occurred.
