Hi,
I have a Dell 3115cn that has worked fine until recently, I changed the magenta cartridge like normal a couple of days ago and since then I have been getting magenta marks left all over the page when printing (see images). I have tried changing to another new cartridge and still see the same issue, I have noticed that I am also getting the same marks left on the transfer belt in the printer, I have gone through and cleaned it all but still same issue. The only time I don't get it is if I print in black and white only.
Has anyone else had this issue and know how to fix it?
Cheers,
Luke.
