ARM207 Noise

[bdcrandall13]

I have a continuous problem with an ARM207. Machine is 4 years old and for the last year or so has intermittently been making a "rubbing" sound before and after copies are made. It is a very quick but noticeable noise that does not seem to affect copy quality. I have changed the drum, process unit, DV box, fuser and cleaning blade multiple times. To me it sounds like the drum rubbing on the cleaning blade. Does the motor rotate backwards slightly when copying is completed? I also saw a post somewhere that it could be caused by the felt pads on the drum unit. I also had a thought that it could be something in the paper feed section. Machine only has 100k copies on it but is a fairly dirty, (dust,) environment.
Thanks in advance.

Re: ARM207 Noise

Here's the only database entry I've got on noises for Pegasus:

Buzzing noise when copying or printing from tray #1 on AR-M205. Vibration from the lower vertical feed clutch. Clean and re-grease the lower vertical feed clutch.

Most everything is driven by the main motor on the Pegasus. And it does not reverse to clean the drum blade. And the cleaning blade tension is on all the time, it doesn't tap.

Re: ARM207 Noise

The sound it is making sounds like it could possibly be coming from somewhere in the paper feed section. I will do some checking in that area next time I am out there.

Re: ARM207 Noise

I have found this noise to be either the drum unit (take a test unit to check) or the fuser, most times the drum. It is hard to locate since it almost impossible to watch the machine in operation. When you rebuild the drum unit do you replaced the side seals?

Good luck.

I have replaced the entire Process unit with a used one and a new one and the noise comes back. This last time it seemed to work for a longer period of time before returning.

Re: ARM207 Noise

It's not real common on this model, but perhaps you're getting cleaning blade vibration. The test is to prime the blade with dusting powder, then test.

In situations where the customer does a lot of very low fill copies, the drum blade can become starved for toner to lubricate it. =^..^=

Re: ARM207 Noise

If u are sure that the noise isn't comming from exit areea, in wich case u have a lot of H5, then u should pull out the registration rollers(4) which are mounted on an shaft which has bushes where the dirt is accumulating. Next is the cleaning felt from the fuser wich is ''moving'' if the copies are made in small numbers/job.
And u should check the shaft in wich is the drum inserted when u put the drum unit back into is place.

If u remouve the back then u can press the swich and see the machine in action.

Re: ARM207 Noise

and, do you check the clutch from the ps roller?

... Next is the cleaning felt from the fuser ...

Thanks vlad, I had completely forgotten about this. The cleaning felt will build up with toner over time. When enough toner has collected the toner on the felt will become sticky, and make a rubbing noise. You can replace the felt or scrape it with your pocket knife, then add about a dozen drops of fuser oil to help it stay clean longer. You'll know if you put on too much fuser oil. The paper will jam in the fuser until enough of the fuser oil has evaporated off or transferred to the paper. =^..^=

Ok this makes sense. I changed the fuser about 6 months ago and the noise seemed to get better. There have been so many changes that it is hard to point a finger at the cause. I will check out the felt pad and report the results.

Re: ARM207 Noise

if i remember correctly, there is a plastic cover below the drum that is held on by one or two screws. I had these come loose one day on a machine i worked on and got the same result .

Re: ARM207 Noise

sounds like its the drum. you are hearing the blade squeak when it starts up and when it stops. Never had a problem with it, its just the rubber on the drum. if the customer has a problem with it adding more powder may get ride of it. good luck.
