It could be related to the quality. I would recommend only purchasing cartridges from a Xerox partner to ensure high quality.
Hi none of these seem to apply, its a new cartridge - which is fine in the beginning, and then the print starts to shade
Do you think its maybe the quality of the cartridge that is the issue perhaps?
I searched and found this article that may help you with your shading issue.
So when I'm printing, its shaded on one side. This happens with most of my new cartridges after a short amount of usage. I can attach the supplies information can anyone advise what needs to be replaced or indeed what the issue is? I am aware a few bits are a bit over what they should be, this was gifted to me by an old friend when he was clearing out his office its a good wee workhorse, would love to be able to save it!
