Bizhub 452 C-3B07 Error

[LCS]

[QUOTE=TALALOO;195880]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


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.

[and]

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.
