Toner save mode (page 23) Reduces toner consumption by approximately 10%. Power save modes (page 24) The copier has two power save modes of operation: preheat mode and auto power shut-off mode. q Preheat mode When the copier enters the preheat mode, the power save ( ) indicator will light up and other indicators will remain on or off as before. In this condition, the fuser in the copier is maintained at a lower heat level, thereby saving power. To copy from the preheat mode, make desired copier selections and press the print ( ) key using the normal copying procedure. Auto power shut-off mode When the copier enters the auto power shut-off mode, the power save ( ) indicator will light up and other indicators will go out. The auto power shut-off mode saves more power than the preheat mode but requires a longer time before starting copying. Then make desired copier selections and press the print ( ) key using the normal copying procedure. 4 Special functions q Auto clear (page 24) The copier returns to the initial settings a preset amount of time after the last copy is made.
