Sensor Operation
There are three phases in the operation of the proximity sensor:
• First, the sensor detects the presence of the operator within the arc in front of the machine, and then
signals the machine to leave the STR mode (or Engine OFF mode) and enter the Pre-recovery
mode.
• Second, as soon as the machine enters the Pre-recovery mode it resets the Engine Off mode timer
for 5 min. If the operator does not touch the machine for 5 minutes, the machine slips back into the
Engine Off mode. If the operator touches the LCD, or opens and closes the ADF or front door, etc.,
the machine shifts to Standby mode.
• Third, once the machine enters Standby mode, if the operator does nothing to start operation, the
machine will gradually step down from Standby mode to Lower Energy mode, Quiet mode, Engine
Off mode, and then finally to STR mode.
Operation Modes
Here are more details about these operation mode levels.
• STR mode. Suspend-to-RAM mode. The power supply to the CPU, adjacent chips, and the clock on
the controller board is shut down.
• Engine Off mode. The fusing lamps and other engine components remain off. The operation panel
backlight is off, but there is power supplied to the operation panel and the controller boards.
• Pre-recovery mode. The operation panel and HDD are on but the engine components remain off
(Energy Save mode). However, the operation backlight still remains off, so there is no change on
the operation panel to indicate that the machine has shifted from STR mode, through Engine Off
mode, and into Pre-recovery mode.
• Quiet mode. Fusing lamps still remain off, but the HDD and SD cards are accessible so the machine
can receive jobs (Data In) and incoming faxes.
• Lower Power mode. Finally, power is restored to the fusing lamps but maintained at low
temperature.
• Standby mode. The machine is ready to operate.
User Tool
The operation of the proximity sensor can be switched off and on with a User Tool setting.
1. Touch "User Tools" on the operation panel.
2. Select System Settings > General Settings > Human Detection Sensor
3. You can switch the sensor off/on by selected Disabled/Enabled. The default setting is "Enabled".
