Off Mode - Canon iR5000 Service Manual

CHAPTER 2 MAIN CONTROLLER

4.7 Off Mode

In off mode, a minimum number of logic circuits on the main controller PCB are left
powered, and all others including the CPU (+3.3 V) all night power supply are tuned off.
This mode is used only when the copier is used on its own (i.e., without network print op-
tion/PDL print option).
4.7.1 Shift from Standby Mode (standby → off mode)
A shift is made from standby mode to off mode under the following conditions:
• The control panel power switch (soft switch) is off.
• Standby mode has continued for a specific period of time (selected in user mode).
4.7.2 Shift from Low Power Mode (low power mode → off mode)
A shift is made from low power mode to off mode under the following conditions:
• The control panel power switch (soft switch) is off.
• Low power mode has continued for a specific period of time (selected in user mode).
4.7.3 Return to Standby Mode (off mode → standby)
In off mode, an auto return to standby mode by means of an external command is not pos-
sible. To turn on standby mode, the control panel power switch (soft switch) or the main
power switch must be turned off and then on.
The return operation is exactly the same as when the machine is turned on.
4.8 Power Off Mode
The machine is in power off mode when its main power switch remains off.
To return from power off mode, the main power switch must be turned on, thereby auto-
matically returning the machine to standby mode.
