B. Operations

1. 2-Speed Rotation Control

The rotation of some of the fans used in the copier is controlled so that they operate at full speed
(24 V) or half speed (15 V) in response to a switch of voltage by the voltage switching circuit of the
respective fan. (Table 9-401)
If an error occurs in the rotation of a fan, the copier indicates 'E804' on the control panel. To
reset the copier, remove the cause, and turn on the power switch. (Table 9-401)
