When the machine is not used, the energy saver function reduces power
consumption by lowering the fusing temperature.
This machine has four types of energy saver mode as follows.
1) Energy saver mode (called 'panel off mode' in the operation manual)
2) Low power mode (called 'energy saver mode' in the operation manual)
3) Auto off mode (copier configuration only)
4) Night mode (copier/fax, copier/printer, copier/fax/printer configurations only)
These modes are controlled by the following UP and SP modes.
• Energy saver timer
• Low power timer
• Auto off timer
• Energy saver mode
• Auto off disabling (UP mode only)
The way that the machine operates depends on the combination of installed
equipment (copier only, or whether a fax and/or printer is installed).
