2.3.2.1 Image Resolution
This printer has an print image resolution of 600 dpi (dots per inch).
Print image resolution is determined by the number of dots (or pixels)
per inch of beam sweep and the number of sweeps per inch of paper
travel.

2.3.2.2 ROS Control
The Laser Diode PWB controls laser power monitoring and adjustment.
The MCU PWB controls the rest of the ROS Assembly functions. C262
main board processes video data sent from a host computer. The ESS
PWB then passes that data on to C262 main board which controls the
flow of video data to the Laser Diode PWB. C262 main board switches
the laser diode on and off according to the image data being sent from
C262 main board. When the data signals for a black pixel, C262 main
board rapidly switches the Laser Diode on and off. The MCU PWB
provides the +5VDC needed to drive the Laser Diode. The CRU
Interlock Switch cuts +5VDC to the Laser Diode when the EP Cartridge
is not in place in the printer. The MCU PWB provides the +24VDC
needed to run the ROS Motor. The MCU PWB also provides the signal
(/RMOT ON) that switches the ROS Motor on and off. To reduce ROS
Motor wear, the MCU switches off the ROS Motor after 15 minutes of
printer inactivity. The MCU PWB provides the +5VDC (signal 5V)
needed by the SOS Sensor. The Sensor returns information about the
start of each scan to the MCU through the /SOS signal.
