3-2. ROS Control

3-2-1. Scanner Motor Rotation

ON/OFF control of rotation of the scanner motor can be performed as follows according to each operating mode:
Operating mode
On-line mode
Test print mode
Revolutions of the scanning motor corresponding to resolutions are as follows:
Resolution
300dpi
dpi (dot per inch: the number of dots per inch)
RPM (revolutions per minute)

3-2-2. Warming up of ROS

On starting warming up of the ROS, the scanner motor rotates, the interval of SOS signals becomes shorter than the
READY standard value three times in succession, leading to the termination of the ROS warming up (the scanner motor
is rotating at constant speed).

3-2-3. ROS Standard Value

ROS standard value
READY standard value
FAIL standard value
Reference: Runaway of the scanner motor including a speed increase of over 1% prevents a laser beam from entering into
the SOS sensor. When FAIL standard value is not obtained, an error message of "CALL SERVICE 03" is
displayed.
