Theory of Operation
Printer Controls
Paper Size Control
The paper size detection for Trays 2, 3, 4, and 5 is determined by the Paper
Size Switch, composed of three microswitches, located in each paper tray
slot. The switch condition is set by moving the paper guide in the tray. This in
turn sets the plastic actuators on the side of the paper tray to a specific
position that activates the switch combination indicating the media size.
Selective Control; Paper Pick
Unless changed in printer setup, the default tray is Tray 2. Trays in the optional
1100-Sheet Feeder are identified as Tray 3 and Tray 4. The tray in the optional
550-Sheet Feeder is identified as Tray 3. If both optional Feeders are
installed, the 550-Sheet Feeder tray is identified as Tray 3, and the trays of the
1100-Sheet Feeder are identified as Tray 4 and Tray 5.

The Phaser 6300/6350/6360 printer supports the installation of only one
550-Sheet Feeder. Attempting to install a second results in an
unsupported configuration error.
Laser Light Intensity Control
The Laser Unit in the Phaser 6300/6350/6360 printer has four laser diodes:
one each for yellow, magenta, cyan, and black. The diode control circuitry
adjusts the light intensity for each color automatically. Image data is
transmitted to the laser diodes in the Laser Unit as digital signals. The laser
diodes convert the image data from digital signals to optical signals. The
Laser Unit monitors and adjusts the intensity of the laser beams to attain a
stable electrostatic image.
