Lexmark CX310dn Service Manual

There is a duplex unit on the printers. The duplex unit is built into the front cover and Tray 1.
Note: The ACM is also known as the paper feed roller assembly.
Transport components
The paper is fed from the tray into the printer by a pick roll and sent to two sets of feed rollers which time the paper
to enter the Electrophotographic Process (EP Process) at just the right moment. The feed rollers push the paper to the
transfer module where the image is transferred to the page.
The transfer roller moves the paper to the fuser where heat and pressure are applied to the page. The fuser rollers
push the paper toward the exit bin and past the exit sensor. The exit rollers guide the paper into the output bin.
Note: If the printer posts a paper jam message but no paper is found, paper dust or paper particles may have fallen
into one of the sensor eyes. Use a can of compressed air to gently clean the sensor.
Bubble sensors
The printer uses two bubble sensors to adjust the speed of the fuser motor to better avoid image smearing and paper
jams.
The fuser bubble sensor, located before the fuser in the paper path, senses the bubble, or amount of curve in the paper,
when it hits the fuser rollers. If the curve is too great, the fuser motor speeds up to avoid causing a paper jam. If the
curve is too small, the motor slows to avoid smearing the image.
