When I turn on copier don't power up, I have change the a/c card pwba-ac twice, I turn on and works after i turn off and try again to start up, the ac card won't work, Any idea?
thank you
Something could be shorting it out. Which ac pwb have you changed? If the same thing happens when coming out of power save (it wont come out) then its the low voltage power supply. a common one with these machines

just check the wire connection behind the right side of the machine
open the right side cover (upper) and press all the socket of the wire
and check
i have the same problem few days back
Hy, your dc 12 has a problem whith the ac driver pwb is the one with some relays on it close to the lvps pwb. The reley who have to mantain the current flow to the lvps is brocken. That is the solution.
Check the fuse in the plug, 13 amp, the trip switch on the back of the machine, if not then its probably a power supply problem on the machine. you dont actually state the docucolour which has this problem.
Also as for the waste containers, why do you want to know about something that is a given. The answer is they work differently, if you really want to know about the inside workings i will tell you but you will be bored
The 2045 has a toner and Dev collection as dev ages ist looses its ability to charge and discharge and is then deposited into what is called the toner waste container. It has a different name but serves the same purpouse. TO answer the Question on the no power somemore info is needed. When you turn on the DC12 can you hear the fans run? do your hear any other noises when you turn your unit on??
Quita la tapa de el drawer
Obseva la media lunita de el 2nd BTR Black & yellow Cheat el sw de la puerta Si no hace el intento de girar . Quita la tapa posterior y observa si gira el motor principal y el motor de el cilindro si no giran tienes un problema en la AC driver 5Volts o en los 24 volts verifica tambien los fuses de la PWB de interconexion y de la Ac driver suerte

�� Possible parts that caused the error�� Troubleshooting
�� Photoconductor Unit �� SENSOR TR-0
�� HARNESS-ASSY XERO �� MOTOR ASSY P/R
�� HARNESS ASSY MAIN �� PWBA MCU�� LV/HVPSStep Check Yes No
1 Check of Photoconductor Unit attachment
Re-attach Photoconductor Unit.
Does the error recur when the power is turned
ON?
Go to Step [2]. End of
procedure
2 Operation check of Photoconductor Unit
Is the Drum of Photoconductor Unit rotating?
Go to Step [3]. Go to Step [10].
3 Check for dirt on silver seal on Belt in
Photoconductor Unit
Remove Photoconductor Unit.
Turn gear of Photoconductor Unit until silver
seal attached to Belt can be seen.
Is silver seal dirty?
Replace
Photoconductor
Unit.
Go to Step [4].
4 Check of SENSOR TR-0 (TR0 Sensor)
attachment
Remove Photoconductor Unit.
Is SENSOR TR-0 attached securely?
Go to Step [5]. Re-attach
the SENSOR
TR-0, and go to
step [5].
5 Check of dirt and foreign bodies on surface
of SENSOR TR-0
Remove Photoconductor Unit.
Are there any dirt or foreign bodies on the
SENSOR TR-0 surface?
Clean to remove
any dirt or
foreign bodies,
and go to step
[6].
Go to Step [7].
6 Does the error recur when the power is
turned ON?
Go to Step [7]. End of
procedure
7 Operation check of SENSOR TR-0
Remove Photoconductor Unit.
The voltage of P416-2 ↔ P416-3 on PWBA
MCU is 5 VDC when silver paper or other
reflective object comes close to the sensing
area of SENSOR TR-0, and is 0 VDC when
the object is released?
Replace PWBA
MCU. (p.404)
Go to Step [8].
8 Check of 5 VDC power supply to SENSOR
TR-0
The voltage of P416-1 ↔ P416-3 on PWBA
MCU is 5 VDC?
Go to Step [9]. Go to Step [14].
9 Continuity check of HARNESS-ASSY XERO
Disconnect the P/J416 from PWBA MCU.
Do all of the wiring below have normal
continuity?
J416-1 ↔ J108-3
J416-2 ↔ J108-2
J416-3 ↔ J108-1
Replace
SENSOR TR-0.
(p.361)
Replace
HARNESSASSY
XERO.
10 Check after replacement of MOTOR ASSY
P/R
Replace MOTOR ASSY P/R. (p.398)
Does the error recur when the power is turned
ON?
Go to Step [11]. End of
procedure
11 24 VDC power supply check to MOTOR
ASSY P/R
Disconnect P/J201 from MOTOR ASSY P/R.
The voltage of J201-1 ↔ J201-2 is 24 VDC?
Go to Step [12]. Go to Step [13].
12 Continuity check of HARNESS ASSY MAIN
Disconnect the P/J403 from PWBA MCU.
Is the continuity normal between all terminals
of J403 ↔ J200?
Replace PWBA
MCU. (p.404)
Repair broken
or shorted part.
13 Continuity check of HARNESS ASSY MAIN
Disconnect P/J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J502-9 ↔ J201-1
J502-10 ↔ J201-2
Replace LV/
HVPS. (p.407)
Repair broken
or shorted part.
14 5 VDC power supply check to PWBA MCU
The voltage of P410-3 ↔ P410-4 on PWBA
MCU is 5 VDC?
Replace PWBA
MCU. (p.404)
Go to Step [15].
15 Continuity check of HARNESS ASSY MAIN
Disconnect P/J410 from PWBA MCU and P/
J502 from LV/HVPS.
Do all of the wiring below have normal
continuity?
J410-3 ↔ J502-3
J410-4 ↔ J502-4
Replace LV/
HVPS. (p.407)
