How do I fix this problem? - Black shadows on prints - Color ImageCLASS MF656Cdw

[bdb2]

Apologies for not providing a model number.  Color ImageCLASS MF656Cdw 

Have had this issue since my first toner change.  All was perfect up until then.  Have changed all other toner cartridges since, only black cartridge is leaving these marks.  Cannot see anything outwardly wrong with toner cartridge. Thank you in advance!

How to clean this?

Updated. It's also printed on the image. Tried to "Add product" but consistently got "No matches". Gave me all kinds of OTHER products, but not the printer in question.

We just need ya to tell us what it is, we can add it to the thread title!

Attempted to "Add Product" and... no matches.

Try searching without the "Color", for now we've added it to the title and moved this post to the correct board so our Community is more likely to be able to assist!
