C3320i and fan noise, even in sleep mode

Re: C3320i and fan noise, even in sleep mode

Yes it is true this series 3320i/3350i/4050i have a noisy fan for the cpu. I asked KM if there was a solution, but there wasn't one.

It is because they spend all the possible money / budget in R&D to make UI / menus of admin and service as complex as possible.

It seems the only way is to use the flag 37 and put it in deep sleep using long press on power button. Bit weird.
Or to switch off

One thing I have to admit . KM end users menus are fine. Print quality is fine. Scan quality is fine. Connectivity is fine. And that is the most important.

I will try Ricoh an another day.

Re: C3320i and fan noise, even in sleep mode

Interesting.

I need to investigate and try again. At first try fan was never stopped and turns days and night. (9W consumption).

If I'm right fan does not stop while pressing power and stopped while long pressing power + switch 37 on

In my case the fan stops in deep standby with default of the box settings. It is only a problem in a silent enviroment and the customer is sitting near the device.
I have changed the fan with a cpu fan from a bizhub c220 for a test, they have a bit less power but the noise persists. The bizhub c220 can switch off, the new i-series does not.
And it is not a fan decibel problem but rather a problem of placement of the fan.. air flow directly out of the housing without an insulating deflection.

Hi,

Thanks for sharing. This is what I think too.
DO you have some references for alternative fan?

Re: C3320i and fan noise, even in sleep mode

I wrote to change the fan is not the solution.

Re: C3320i and fan noise, even in sleep mode

You are right.

Did you try something else?

Actually I just switch off the printer (thank @ home apple and Eve ).

Re: C3320i and fan noise, even in sleep mode

update of my printer :

I just want to share something as strange as good.

since a week, the fan of my Konica is now switch off will in deep sleep.
No human intervention

I don't know if it is an update (OTA?), if it is by design (for exemple some kind of break in period), but now I can't hear this noise at the end of the day

This make me love my machine again

regards

In europe you can order modified base boards via the erc portal. Special firmware must also be installed (GG3-E9)

Interesting.

Now for unknown reason, fan does not switch off anymore when in deep sleep.

I do really really really prefer Ricoh... Dooh

Re: C3320i and fan noise, even in sleep mode

Today i have a brand new +3320i with a fan that does not stop in sleep mode.. he runs constantly and after the machine is in standby the fan run for 10 sec. 0.5sec off and on again /repeating on of on of.
Its my first one with this behavior.

Any hints?

Here in Europe the only solution for this annoying issue (due to bad design I guess) is to order a modificated base board and replace it.
And you have to install a special firmware.
Are you a technician?

Hi,

Thank you for reply.
unfortunately no. I'm not a technician but power user. I'm not afraid with admin functions.
While I've bought this machine and create an account here, I've discover some kind of black box

For sure my next copier will not be a Konica. Konica is great quality but admin experience and end user experience is pain in the ass

(i do not even found how to simply scan to multiple mail only by selecting mail destination without selecting add then validate etc)

Yes i'm technician and dealer. But i think here is a other problem. New machine and the other machine same batch runs correct.

You mean some others C3320i can go in sleep mode without fan ?

Just crazy.

Will contact the dealer
