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/OFF control of scanner motor rotation
On-line mode
Control by main logic board
Test print mode
On turning on power, rotation starts, constantly remaining in the ON state.
Revolutions of the scanning motor corresponding to resolutions are as follows:
Resolution
Revolution
300dpi
6614RPM
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
Contents
READY standard value
Interval of SOS signals corresponding to over 98% of the specified revolution of the
scanner motor
FAIL standard value
Interval of SOS signals corresponding to below 90% of the specified revolution of the
scanner motor
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.
