Re: MPC4500 gear pump tone problems


i get the feeling you are not a tech?
You need to search previous posts as toner pump issues are not new to these models

Re: MPC4500 gear pump tone problems

hi all
after i change the yellow pump the back of the machine sound loud and sound like gear scrape. than i try change other thing aswell .

any body have idea what is problem please ?

Before "Service": No noise
After "Service": Scraping noise

....so it never crossed your mind that maybe (just maybe) you have installed it incorrectly?
And what "other things" did you try to change?

What is the part number of the pump? And, is it a second hand part or new?
The number should be B223-3252.

Other causes of noise around this area is the drum and/or dev unit.

Re: MPC4500 gear pump tone problems

theres a white plastic clip missing for that clutch, have you taken it off? theres no need to touch that when changing the toner pumps

I think you're confused and you're not changing the toner supply pumps. But another piece ...

I would appreciate it, explain concretely which piece has managed its change / repair and take into account that as indicated by other technical colleagues, a "white piece" that holds the main axis of that engine is missing.

That is the clutch for the yellow toner pump. With that clip missing, no wonder its making noise.
