Bizhub 452 C-3B07 Error

[remstaler]

I have a C -3B07 error on my Bizhub c452 .When i do a trouble reset the error dissapier, but after printing the first page it comes up again .

Total counter is on 262709 pages .

Fusing unit status 47 %

Could it be the fusing unit or the IH power board ?

Regards

[bizhub1]

Yes it could, and it also may be the coil unit.

[remstaler]

i changed now the fusing unit , but still have the same problem. The funny think is that the paper always get stocked in the fusing unit. when this happend i hear a funny noise .

[kronical]

How far in does the paper get into the fuser before it stops up, you may have a damaged drive gear

[remstaler]

it gets not far in . i also hear a funny noise like a jumped gear. But when i manually turn that blue wheel on the right side, that paper get smoothly thru the imagine unit.

i ordered now the ih power board, will get it next week and will try.

If you are getting a gear chatter, then there is definitely a drive issue. Don't rely on the fuser jam access dial to see if there is an issue as it bypasses the actual drive mechanisms. Note the gears above the fuser that pivot out of the drive position when the door is opened.

I can help you to give the reasons that give you this code:

C3B07 IH input power error :

1• While the IH heater was on, input power

stayed at the high voltage power detection
value or over for more than the predetermined period of time.
2• While the IH heater
was on, input power was at the low power detection value or

under for more than the predetermined period of time.
3• While the IH heater

was on, input power was at the high voltage detection value orover for more than the predetermined period of time.

4• While the IH heater

was on, input power was below the low voltage detection value or

under for more than the predetermined period of time.
5• While the IH heater was on, inverter power stayed at the

upper limit value or over for more than the predetermined period of time.

6• While the IH heater

was on, output voltage halt was detected .

Step Action:

1 Check the connection of the fusing unit.
2 Check the fusing unit, degaussing coil unit,

IHPU, PRCB and REDB for proper connection and correct or change as necessary.

3 Change dega

ussing coil unit .

4 Change IHPU

5 Change PRCB

6 Change REDB

GOOD LUCK.

Do you have the service manual? It provides some insight into this malfuntion. If you need it, i'd be happy to provide it for free. Just contact me.

IH power board certainly.I have already replaced many times this part.

[remstaler]

you mean the gears above the fuser can cause the problem ? its hard to localise the noise but i think its comming from inside the machine and not from the fuser aerea.

Hi I have the same trouble C3B807 but with another model Bizhub 754e, I just like to ask if it happen for you to have the schematic diagram of the IH power supply?

thank you
have a great day.

Re: Bizhub 452 C-3B07 Error

IH power board certainly.I have already replaced many times this part.

Problem

[Symptom] C-3B07 or C-3B02 caused by the particular component failure happened in the specific market only. * So far, it was confirmed that this same components failure happened only on Hong Kong market. [Cause] The capacitance of C3 or C4 mounted on IHPU was decreased. This was caused by the excessive self-healing effect of the capacitor. -Applicable part number of IHPU (For AC 200V area) C652/C652DS/652 ............ A0P0 M401 04 C452/C552/C552DS/552 .... A0P1 M401 04

Solution

[Countermeasure] In order to increase the strength against the self-healing effect, the thickness of insulating layer of the capacitor will make thicker than the current one. The part numbers will be changed and a PMN will be issued for the change later. [Production application schedule] C652/652DS/652 ................. around August 2011. C452/C552/C552DS/552: ...... around October 2011

Exactly, I replaced several items too.
