Hi
Does anyone know if the Ricoh MPC 7501 charge roller fits the MPC7500. I know the parts numbers are difference but is there actually a difference in the product?
Many Thanks

Ricoh MPC 6000 / 7500 smudgy, blury text

Hi

I found out they are both the same. On another note, I cant start a new Post from my computer so using this, I keep getting Blury, smudgy copies on black units on a few MPC 6000 and 7500. Its like its got moisture on the drum as once its done a few hundred copies or warmed up in the day it goes. Is there any cure or has this fault been known before? I am thinking to get some moisture beads they have in packaging to put bu the black unit in the machine somewhere to help remove the moisture were having at the mo.

Any advice would be cool.
