Printer Controls
Control of Paper Size
The paper size control is determined by a paper size switch located in each paper tray
slot. The switch setting is set by moving the tray which in turn sets the plastic
“fingers” on the sides of the paper tray to a specific postion.
Paper Size Switches are indicated as SW1, SW2, and SW3.
Selective Control; Paper Pick
When not controlled by the Engine Control Board, the paper pick selected at power
ON is; "Tray 1". Trays in the optional High-Capacity Feeder are "Tray 2" and
"Tray 3" respectively.
Laser Quantity Control
Image data is transmitted to the laser diodes in the Laser Unit as digital signals and
the laser diodes convert the image data from digital signals to optical signals (data
expressed with blinking laser beams). If variations in the light intensity from the laser
beams or variations in the optical system, such as lenses or drum sensitivity, cannot
obtain a proper electrostatic image, then the laser diodes monitor and adjust the light
intensity of the laser beams to control and attain a stable electrostatic image. The
Laser Unit in the Phaser 6200 printer has four laser diodes: one each for yellow,
magenta, cyan and black, that adjust the light intensity for each color automatically.
