Theory of Operation
Media Size Detection
Media size is detected using the Registration Sensor. The length of the media is
determined by the length of time the Registration Sensor remains High indicating
media in the registration section.
If the media size specified by the controller does not match the media size
detected by the Registration Sensor, the system displays an error message on the
Control Panel. The sheet causing the size error continues through the print process
and is output to the tray. Operations for subsequent sheets are specified from the
controller.
Output Tray
Media is transported from the Fuser to the output tray using the Exit Roller. The
Exit Sensor monitors the media output.
For printers without an installed Duplex Unit, the exit roller is driven by the Main
Motor. During 1-sided printing, the exit roller rotates in the forward direction and
feeds the media onto the output tray. If an optional Duplex Unit is attached, the
exit roller is driven by the Duplex Unit.
