Theory of Operation
Duplex Paper Path
When 2-sided printing is selected, side two is printed first, the image being
printed is the first image. After the first image prints, the paper is reversed and
is fed through the duplexer and back up to the feed roller with side one
positioned for printing with the second image.
Paper Feed Sequence
When the Main Board is ready to feed paper, it energizes the paper feed
solenoid. The solenoid armature releases the clutch and the Pick-Up Roller
makes one revolution. This drives the paper to the Feed Roller and the Retard
Roller. The Feed Roller and Retard Roller drive the paper to the Registration
Assembly, which in turn drives the paper towards the transfer area. Before
arriving at the transfer area, the paper actuates the Feed Sensor.
Paper Transport
The Registration Assembly continues to drive the paper into the transfer area,
where the image is transferred from the drum to the paper.
After the image transfers, the paper continues to the Fuser Assembly for the
fusi
ng the process. In the Fuser Assembly, the Heat Roller is heated by a heat
element and the paper passes in between the Heat Roller and the pressure
roller, where toner melts onto the paper to form a permanent image. The
temperature of the heat roller is monitored by a Thermistor that sends signals
to the Main Board.
The Fuser Assembly drives the paper into the Exit Rollers, which drive the
pap
er
into the output tray. When printing the first side of a duplex print job, the
drive direction is reversed when the Exit Sensor is actuated. Paper is then
directed into the Duplex Unit for printing on the second side.
Paper Feed Drive
The drive for all rollers is provided by the Main Drive Motor and a series of
drive gears. The Main Motor is used for paper feed, fusing, and the duplex/exit
roller reversal for 2-sided printing. When the main motor turns, all the paper
path components also turn except the Pick-Up Roller. The Pick-Up Roller
assembly moves the paper along the path with the Feed Solenoid. There is a
separate Developer Motor for the Print Cartridge.
