Standby ModeThe machine is in operation or is ready to start operation, with all its loads supplied with power.2. Power Save ModeThe machine deceases the control temperature while the fixing assembly is in a standby state according to the selected power save rating (variable through 'changepower save mode' in user mode; default: -10%), thus decreasing the power consumption.Conditions Initiating a Shift from Standby Mode (standby -> power save)Operation mode Main power SWOFF Deep sleep Shallow sleepLow power (&power saving) Door open Fixing error Print (*2)Main power switch OFF ON ON ON ON ON ONAll-night 3.3VR OFF ON ON ON ON ON ONNon-all-night 13VA OFF OFF ON ON ON ON ON13VB OFF OFF ON ON ON ON ON13V4A OFF OFF OFF OFF ON ON ON24V1x OFF OFF OFF ON ON ON ON24V2x OFF OFF OFF ON ON ON ON24V3x (DC relay) OFF OFF OFF ON OFF ON ON24V4x OFF OFF OFF OFF ON ON ONAC relay OFF OFF OFF ON ON OFF ONSub power supply(24V) OFF OFF OFF ON ON ON ONOptional powersupply (24V) *1 OFF OFF OFF ON ON ON ONSRAM PCB manganese dioxide lithium battery (3 V, 100 mAh)DC controller PCB lithium battery (3 V, 6000 mAh)Life 10 yr or more (true of both; with power plug removed)Replacement not possible in the field on its own.
