Shutdown Sequence; Motion Sensor - Canon imageRUNNER ADVANCE 715iF III Series Service Manual

NOTE:
To achieve faster startup, the progress bar and the active PCB are not synchronized.
For this reason, the progress bar cannot be utilized for troubleshooting.
For information about troubleshooting, refer to "Related error codes (major error codes)" shown below.
Related error codes (major error codes):
• E602-0001: HDD detection error
• E614-0001: Flash PCB detection error
• E614-0002: Error in file system on the Flash PCB
• E614-4001: Error in file system on the Flash PCB
• E614-4002: Error in file system on the Flash PCB
• E748-2010: Flash PCB error / HDD error
NOTE:
When the following errors occur, the system of the host machine has not been started normally. Therefore the error code is not
recorded in the log.
E602-XX01, E614-XX01, E748-2010

Shutdown Sequence

Before shutting down the power supply, it is necessary to perform the HDD completion process (Purpose: to prevent damage on
the HDD) and execute the fixing disengagement operation. This sequential process is called "shutdown sequence". The shutdown
sequence has been manually executed with the legacy (existing) models (by holding down the power supply switch on the Control
Panel for a specific duration).
With this machine, the Main Controller PCB detects turning OFF the Main Power Supply Switch, and the shutdown sequence is
started and executed automatically.
Note that the maximum shutdown time with this equipment is 110 seconds.
NOTE:
When the power supply is stopped without advance shutdown of the equipment, or the complete deletion process of the HDD
(deletion of the primary file) failed to be completed within the shutdown time (max. 110 sec.), data matching is checked at startup.
The progress bar is displayed during the data checking.

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.
