e Studio 355 Noisy

[grrgto]

e studio 355 noisy at startup and when drum is turning.
Noise would go away after reseating the dev unit.
Rebuilt the dev unit now the noise does not go away.
Copies are fine but the "gear box rattling" type noise not going away anymore.

Any ideas?

Check the drum drive, pin in drive shaft sheers creating drive issues & noise

Mostly you'll just get E010 jams for the sheared drum drive pin. If you reach into the cavity and manually turn the drum drive you won't be able to feel the resistance of the motor. But not much noise.

The doctor blade might be making contact with the mag roller, making that noise. Or the paper dust collectors at the registration roller might be flipped, but you'll identify that pretty easily. Manually turning the registration roller will make the noise. =^..^=

Fuser is biggest cause of noise on that series machine
