2.3 Parts Names and Functions
Document scanning and feeding
Printing and paper feeding
Names Functions
Document detection actuator This detects whether documents are set on the document tray.
Document pick-up roller This pulls documents loaded in the document tray into the ADF.
Document separation roller,
ADF separation pad
This separates documents sent by the document pick-up roller in
single sheet.
Document feed roller 1 This feeds a document to the CIS unit.
Document scanning position
actuator
This detects the leading edge of document pages, indicating the
scanning start position.
This detects paper jamming in the ADF.
Document feed roller 2 This ejects the scanned document to ADF document support.
Names Functions
T1 paper pull-in roller This feeds recording paper from the paper tray 1.
T2 paper pull-in roller This feeds recording paper from the paper tray 2.
Registration actuator This detect the leading edge of recording paper, controlling the
printing start position.
This detect the leading edge/ending edge of recording paper,
identifying the recording paper size.
This detects paper jamming in the rear.
Paper feed roller The leading edge of recording page hits the stopped paper feed
roller, correcting inclination of the paper. After the correction, the
paper feed roller rotates, feeding the paper to printing start position.
Paper ejection roller This feeds printed recording paper to the switchback roller.
Switchback actuator This detects whether the printed recording papers are ejected.
This detects the ending edge of recording paper after printing the
first side when duplex-printing, adjusting timing to reverse the
switchback roller rotation.
This detect the leading edge/ending edge of recording paper when
duplex-printing, identifying the recording paper size.
This detects whether the recording papers are fed from the
switchback roller to the duplex-printing path.
This detects paper jamming in the ejector.
Detect if paper tray 1 is set.
Switchback roller This ejects the recording paper to the ejected paper tray.
During duplex-printing, after feeding some of the recording papers
printed in the first side to the switchback roller, its rotation is
reversed to feed the recording paper to the duplex-printing path.
Duplex paper feed roller During duplex-printing, this feeds the recording paper that are fed in
the duplex paper path to the paper feed roller.
