Exact output voltage readings cannot be confirmed with this diagnostic test, because
of the HVPS design, and also variable types of multimeter.
When ON is selected, you will see the
Exit Motor run reverse at high speed.
When ON is selected, you should hear
the ROS Motor spin up.
When ON is selected, the Offset Tray
flapper roll rotates.
When ON is selected, the Offset Tray
stepper motor rotates.
When ON is selected, the offset shaft
shifts right then returns.
When ON is selected, the AC charge
voltage is switched on. 1000 +/- 100
VAC (see note below)
When ON is selected, the DC charge
voltage is switched on. -425 +/- 40
VDC (see note below)
When ON is selected, the AC devel-
oper bias voltage is switched on. 690
+/- 60 VAC (see note below)
When ON is selected, the DC devel-
oper bias voltage is switched on. 7 +/-
4 VDC (see note below)
When ON is selected, the negative DC
BTR voltage is switched on. -81 +/- 8
VDC (see note below)
When ON is selected, the positive DC
BTR voltage is switched on. 340 +/- 30
VDC (see note below)
When ON is selected, the detack volt-
age is switched on. -930 +/- 100 VDC
(see note below)
When ON is selected, the fan rotates
at fast speed
When ON is selected, the Laser diode
is switched on.
When ON is selected, the DC bias volt-
age is switched on.
