1.2 DC Power RAP
Procedure
ABC
This RAP is used for problems related to the
loss of all or part of the DC Power.
Q
The + 5V and + 15V LEDs, when lit,
indicate that DC voltage is available
on the L VPS PWB.
Initial Actions
Ensure that the connectors PIJ 4, and
PIJ 9, are connectedlseated properly.
(2510 Only): If the Fuse (F1) is failing
intermitently, check that the
thermistor PWB cover
is in place on
the bottom of the thermistor PWB.
This prevents the oiler assembly from
touching the termistor PWB.
If another copier
is on the same
electrical circuit, the cycling of
its
fuser may cause the fuse to fail. An
indication of another copier
is a
251
OIXI 5 transformer noise (hum)
whon tho copiors
is in tho Rost mode.
The
+ 5V and + 15V LEDs on the low voltage
power supply are
lit.
Set the DMM to read AC. Connect the
DMM to
PIJ 4 Pins 1 and 4.
-
ACH is present.
Y N
Ensure the Fuse F1 on the LVPS is not
open. The Fuse is open.
. -
I Replace the Lws PwB.
50 to FLAG 1 and check for a short
circuit. Replace the Fuse
(F1) and
disconnect P1J9. Set the DMM
Set the DMM to the ZOO VDC range. Conned
read and 'OnneCt the meter (-1 to the GND test point on the HVPS and
leads from 'IJ4 pin to 'IJ4 pin
measure the following LVPS voltages:
There is
22 to 25 VAC.
I
Reconnect PIJ 9.
If the problem persists replace the
Controller PWB
(A3).
Connect the meter leads from PlJ4 pin 6
to PlJ4 pin 10. There is 22 to 25 VAC.
Y N
I Replace the Transformer (PL 1.2).
Disconnect PIJ 9.
The
+ 5V and + 15V LEDs on the low
voltage power supply are
lit.
Y N
I Replace the LVPS PWB (A2).
Replace the Controller PWB (A3).
I Reploco tho Transformor (PL 1.2).
PIJ9Pin 14 = + 15VDC
C
P/J9Pin12= + 24VDC
PIJ 9 Pin 3 = + 10VDC (4.2.5 to + 14
VDC)
If any voltage is missing, go to FLAG 1 and
check lor and open circult,
II thore is no
open circuit replace the Low Voltage Power
Supply PWB (A2).
