Guys, could do with some help here concerning a problem that plagued me before and has now come back with avengance!

It is shown in the attached picture where the pcr on a cc53 cartridge (cyan and magenta in particular) becomes covered in rotation lines of the relevant coloured toner.

I have tried everything I can think of to stop this happening but it just doesn't.

When I had this before I put it down to (SEE THIS), stopped using that in favour of yellow toner and saw the back of it.

I am using fresh dedicated yellow toner now, on a new wiper blade with new drum 1/3 wiped in yellow toner and then rotated a few times to clean. You can see it doesn't clean the drum properly until maybe 5 turns?

If I take an OEM empty and put my toner supply side to it then there are no problems, so I am confident the toner is good. If I put the OEM toner on my imaging side the problem occurs.

I have tried taking an oem empty and just slotting a new drum in, no worries there. As soon as I put a new PCR in and then re-install, the problem comes back?!

Do you think I could be damaging the wiper by turning the drum without it being in the printer? I'm clutching at straws here because this has me completely stumped

Sorry for the long post, I wanted to cover everything I have tried and it would be great to know if someone has had this before...
