CHAPTER1GETTING STARTED Power on and off
Sleep mode
If the sleep mode is enabled, the copier will enter the mode once a
programmed length of time has elapsed without any copier
operation after the last copy of a run is made or the power is first
turned on. When the copier enters the sleep mode, the display on
the touch panel will disappear. In this condition, power is not
supplied to the fuser in the copier. To exit from the sleep mode,
press the COPY key.
★KEY OPERATOR Seepage25oftheKEYOPERATOR’SGUIDEfor
setting the sleep mode timer. See page 30 of the KEY OPERATOR’S
GUIDE for enabling or disabling the sleep mode.
Preheat mode
Thecopier will enter the modeonce the set time haselapsedwithout
any copier operation after the last copy of a run is made or power is
turned on.
When the copier enters the preheat mode, the message “PREHEAT
MODE. PLACE ORIGINALS.” will appear.
In this condition, the fuser in the copier is maintained at a lower heat
level thereby saving power. The preheat level is, however, high
enough to allow the copier to come to a ready condition or begin
copying approximately 30 seconds after any key input is made.
Tocopy from the preheatmode, make desired copier selectionsand
press a START key using the normal copying procedure.
★KEY OPERATOR See page 26 of the KEY OPERATOR’S GUIDE for
information on setting the preheat mode.
