Motion Sensor - Canon imageRUNNER ADVANCE 4551i Service Manual

NOTE:
If the power supply is stopped without shutting down the machine, or if the processing to completely delete the hard disk (deletion
of the primary file) fails to be completed within the shutdown time (max. 90 sec.), data consistency is checked at startup, during
which the progress bar is displayed.

Motion Sensor

Function
Automatic recovery from sleep mode
• The machine automatically recovers from sleep mode by staying in the designated area for more than a certain period of
time. The time spent in the area varies based on the setting of sensitivity (4 levels).
• The sensor determines whether a person approaches the above mentioned area is a user. If a person approaches the
machine from the front side, it starts the operation to recover from sleep mode early. If a person approaches the machine
from the side, the sensor judges whether he/she is just a passer to prevent recovery by mistake.
CAUTION:
Recovery time depends on the time for recovery from sleep mode of the host machine. The Motion Sensor outputs the
trigger for recovery from sleep mode. Operation of the Motion Sensor is the same for recovery from Deep Sleep and from
Sleep 1, but time for recovery differs depending on the recovery process of the host machine.
The machine is not recovered by a passer.
• Reduce unnecessary power consumption
• The machine may recover from sleep mode if walking speed is slow. However, if no operation is performed for a certain
period of time, it moves to sleep mode again.
CAUTION:
Since the detection is performed by outputting a certain frequency from the output part and receiving the reflection wave
by the reception part; thus, do not block the sensor area.
