MPC 5000 noise

[Wishbone]

I was trained early on with the Mpc 3500/4500 series but Ricoh has sinced released the Mpc 5000 and I have an account with many of these in there. All these newer copiers make a noise coming from the back side behind the duplex. They all kick on from time to time and make the same noise and the customer is complaining. Does anybody know what that is? I assume it does that for the fuser but I don't have the right answer for them.

I have got a few of these machines out there too, and I've reacted to sounds from them as well. But I never localised them, and it doesn't seem to be a problem, it sounds like it should be there...

Could you describe the sound a bit more?

[Wishbone]

Yeah it's supposed to be there but still doesn't sound good. The Mpc 4500 doesn't make that sound. It sounds like a motor kicking on and off. It runs for about 10 seconds and stops.

The only noise problems I've had have been as a) the print controller was a bit loose and b) the fuser cleaning roller bunged up with the usual crap.

Both of these presented as something between a clicking and a buzzing noise from around the duplex/fuser area but were difficult to pinpoint.

take out the bridge unit take out the 2 clips by the white rollers and throw them out. check if the white rollers are now out of position this is on the exit rollers

Neither machine which I had the problems on had bridge units on. Does the same thing apply?

[FRIDGEMAGNET]

There is a mod for a noise as paper is fed out through the exit/fuser section.

The noise is due to the pressure release mechnasim in the Fusing unit all the MPC 5000 I have heard have it

Have you tried going into SP's and running either the Image Transfer Belt Motor or Black PCU Motor? If you do, you will hear a clicking noise there as well. Actually, now that I think about it, it's almost a thump to. I too was trained on the earlier models as well and do remember this from one of the Savin 3535's I have in the field. Always just wrote it off as the machine lowering the ITB from the K drum unit and raising it back. Not sure about that though.

All the new MPC4000/5000 machines we have setup to date also sound clanky as pressure is applied.

I can understand why customers would think there is something wrong.

[Symptom]
An unusual sound occurs when the power is turned ON, the device Auto Shuts OFF, the cover is closed, and when the fusing unit pressure release motor operates.
It sounds as if a gear is squeaking at the right rear of the device. The customer is especial disturbed because it occurs when the power is turned OFF and when the cover is closed.

Cause]When the pressure release motor unit's worm gear operates, the gear grease is insufficient, and an unusual sound occurs.
[Resolution]
Apply grease to the worm gear unit.
Remove the right rear cover of the device, remove the four screws on the fusing pressure release motor, and also remove the fusing unit. Then, apply grease to the worm gear through the motor gear's hole.
