Hi all,
I have problem with bizhub 950. C3906 shown 3 times a week. the trouble code related with TH 4 and I've already replace it, but still shown. I tried DipSW3 bit 1, it works for 3 days and then the evil code occur again.
Any idea? thank you.

CAUSE: Improper ventilation of cooling fan Cooling Fan/1 (FM1).

SOLUTION: Remove the rear cover and run 50 or more sheets of 12x18 paper. If the error does not return, verify that Cooling Fan/1 (p/n 55FA 8052 1) is properly aligned with the hole in the rear cover (p/n A0G6 1612 00).

Cooling Fan? no. That's normal. The problem is, C3906 occured at least 3 times a week. C3906 related with TH4 and I already replaced it but the evil code still shown.
Any other solution?

I've seen issue's were the manual says it's the lower heat tube when in FACT it's a problem with the upper heat tube. Be sure to check the other one.

RRodgers, could you describe your explanation? I tried to replace TH1, TH2, TH3, TH4 and finally I replace the Fusing Unit. But next day, C3906 occured again. I don't know what's going on with this one.
Thank you RRodgers. I'm waiting for your information. :)

I think I wrote C3906 NOT SC3606.

[RRodgers]

So is it 39 or 36?

[aleksander]

So is it 39 or 36?
Of course C3906. I've never wrote 36**.
Any solution?

ok ...I`m so sory I looked for the Biz pro 920 manual :(

-C3906 ..if the machine have intermitent codes...
it may have problems with de connector (fuser unit to the machine)or the lamp L3...

OK, now working properly. Changing the Fixing Unit, Reset the fusing counter and now it works again. I hope no more C3906 in the future. Thank you guys. :)
