Konica Minolta C252

[JSC]

We seem to have a lot of these machines with squeaking iu's I have re-dusted the drums with no joy, i have also used silicone grease with not much joy. I think the noise is a vibration from the cleaning unit. is anyone else having this problem.

Hi,

i had this problem at the last place i worked for, nothing seemed to fix the squeak! The only thing we could do was replace if a customer complained too much. Dont know if theres been a fix as of yet.

IU Sqeak

Km released a buliten about the Squeaking IU's last month, the drum shaft contacts were not greased at the factory. Just peal back the label on the front of the IU remove 3 screws and the cover comes off, apply any conductive grease to the drum shaft contacts (2 contacts) reinstall the cover and press label back in place. No more squeak!

Thankyou for the info, I have just checked KM infohub in the UK and no bullitin has been posted yet, mabie it is not seen as a big problem here.

I will be checking the contacts on the drum shaft in future.

Thanks for the link, I don't go to Cornwall much these days mainly Devon, Dorset, Somerset, and most of the new installs for C252 have the squeaking iu's , so thanks again.
