[Error Code] Bizhub 750 error code 2401

[cristian]

Can someone HELP me with an 2401 code for an BIZHUB 750, at startup ?
I know that in the manual is the EL lamp disconected, but i have take the whole image unit and make a test on another machine and it s working.
I have checked also the PRCB on another machine and it s working OK.

Hi,
The likely problem is DCPS1
The part number for this depends on your region. Hope this helps

22	57AA84511	DC Power Source /1	A	I	1	1
22	57AE84511	DC Power Source /1	B,F1,G2,H	I	1	1

Anyway, good ideea.

Re: Bizhub 750 error code 2401

Are you telling me you have already replaced the DC power supply? I am talking about the circuit board, not DC power into the machine?

Re: Bizhub 750 error code 2401

Sorry, no. I have only reset the circuit breakers.I will order for an DCPS1 but it will take about 10 days....

Re: Bizhub 750 error code 2401

i HAVE CHEKED THE SAFETY FUSE FROM DCPS1 AND IS OK. IS THERE ANY METHOD TO CHECK THIS POWER SUPPLY?

[cristian]

Re: Bizhub 750 error code 2401

Already cheked the developer suction fan and also changed.But in the manual is clear, means the EL lamp.

Re: Bizhub 750 error code 2401

It is possible to have this code 2401 due to an developper used more than 250000 copies?

Re: Bizhub 750 error code 2401

Extremely unlikely it will be developer related, I have checked global escalations regarding this code, apart from the obvious things you have already tried the issue seems to be a faulty DCPS1. If you check the 24v output from the board you will probably find one line is missing. I have had one strange issue that was the result of the power supply cooling fan being faulty. I cannot remember off hand which model it was.

Re: Bizhub 750 error code 2401

There was a bulletin or a solution about the sensor wiring in trays 3 and 4 damaged by causing this problem.
The wiring for the sensor in the bottom of tray 3 and 4 can be damaged by the large metal plate that lifts the paper can damage the wiring to the "No Paper" sensors.
Solution:
Subject:
C-2401 at power up. C-2803 may also be indicated.
Description:
C-2401 at power up.
Solution:
PROBABLE CAUSES:
1. C-2401 normally indicates a failed erase lamp, although it is caused, in this case, by a bind in the drum carriage.
Remove and inspect the drum carriage assembly. Run the Toner Cartridge Set mode as well as the Developing unit/Drum.

2. Open ICP6 on the PRCB.
Check for broken or shorted wires in Tray 3 area and repair as necessary. Replace the PRCB (p/n 57AA -902 1J). After replacing the PRCB, go to the Service Mode and set softswitch 32, bit 1 to "0" (OFF). Then re-flash the firmware and, after restarting the machine, set softswitch 32, bit 1 to "1" (ON).

The whole image unit was tested on another machine and is working good.Anyway i can not run any of the Toner Cartridge mode or developing/drum because it give me errors due to the 2401 code.I am very interested if you could run the two up mentioned, with this code...

I have checked the wires on tray 3 .Seems to be ok.I have allready cheched the PRCB on another machine and its working ok.
It remains the solution with an power board, because seems that all the right part is electrically dead.

Re: Bizhub 750 error code 2401

I am curious if the board is working after i will change the fan, or it is burned.All the right part of the machine, starting with main power source and up , including the scanner and fusing unit seems to be electricaly dead, so seems that you are right abot the cause.I ll keep you informed...
