■ Motion Sensor

Features of the Motion Sensor functions are shown below.

• When the machine detects a person staying in front of it (in the area where the sensor works) for more than a certain period

of time, it automatically recovers from sleep mode.

• It judges whether the person is a user or a passerby and controls not to perform recovery triggered by passersby in order to

reduce unnecessary power consumption.

• Criteria for judging whether a person is a user or passerby are shown below.

• If a person approaches the machine from the front, the sensor judges the person as a user and starts recovery from

sleep mode quickly.

• If a person approaches the machine from the side, the sensor judges the person walking fast as a passerby and the

person walking slowly as a user.

• The machine may recover from sleep mode in response to the detection of the passerby walking slowly, but the machine

shifts to sleep mode again if it is not operated within a specified period of time.

Do not block the opening because the sensor generates ultrasonic waves and detects reflected waves.
