There are three phases in the operation of the proximity sensor:

  1. 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.
  2. 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.
  3. 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.
