maddening squeeling on km 8030

[n25an]

I have been searching for the source of a maddening squeel on the km 8030... I greased thee gears on the fuser, the transfer belt, even the gear box but nothing worked until I started looking at the duplexer... here is how I actually solved it... in the duplexer on b2 there are some white rollers.... these guys went dry... i took them out... well they actually popped out and i greased them up... once i did that then the copy went silent... it was sweet... to verify that this is true for you... take out the duplexer... place it vertical on your lap with the back of the unit facing you... and then spin the biggest gear on it... as fast as you can... it should squeek a bit... now just imagine that squeek amplified b y speed and vibration... and you basically have it... another way is to go into service mode and turn on the duplexer... that should narrow it down as well... i think its a 30's service mode... well just wanted to share...

Seen this too. Good catch.

A good way to narrow down these kind of squeaks is to run motors individually in simulation U030. Other common locations include vertical path idler rollers in the right door, idler rollers in the DF-650 top door, the reversing top idler roller in the duplexer, front transfer roller contact, and worn fuser lower cleaning roller bushings.
