Minolta Di-450, C0040
Anybody having a workaround for the service code C-0040 (suction fan) other than replacing that fan? Have now my 3rd machine going down within 3 weeks and I am sick of replacing the expensive fan and especially the idiotic procedure to reach that part.
:mad:

Sorry friend, as far as I know all you can do is replace the fan. This should be the last one as bad luck comes in threes. I just had 3 touch panels on bizhub 250s in 2 weeks go bad.

Strange, I had my first one go bad on a BH350 last week too.....

They are on back order from KM. I am having to hit our machines in the shop to keep customers up.

Since I believe that basically the fan is working but only the speed sensing circuit is not functioning well, here's a workaround when you are in a hurry and need to get the machine up quickly again or also as a semi-permanent solution.
I tapped the speed sensor signal coming from the Power Unit fan (Yellow wire) and connected it to the PJ13-UpperLayer-Pin1 on the PWB-A instead of the original Grey wire coming from the speed sensor of fan M17
Here are the pictures from the experimental setup showing a wire coming from PJ13-UpperLayer-Pin1 going to the pin of the yellow wire from the connector of the power unit fan. I think any fan in the machine can be used but his one was easiest to reach.

I'm sure in the field you will route the wire more professional as I did here......and yes, normally harddrives should not be mounted this way but its my experimental machine as I mentioned before........;)
