5. Control
5.1 Control of Paper Size
The printer doesn’t have switches for detecting paper size, and only length of paper is detected by the
Regi Sensor when feeding paper. If printing data and paper size don’t match, error is sent to the ESS.
5.2 ROS Light Quantity Control
The image data are entered to the laser diodes in the ROS as electric signals (data are expressed with
high and low voltage values), and the laser diodes convert the image data from electric signals to opti-
cal signals (data are expressed with blinking laser beams).
Variations in light quantity of laser beams or variations in optical system (such as lenses) or drum sen-
sitivity cannot attain a proper electrostatic image, therefore, the laser beam light quantity is monitored
and controlled by the laser diodes.
The ROS in this printer has four laser diodes for yellow, magenta, cyan, and black respectively, and the
light quantity is automatically adjusted for each color.
