I saw one machine today and it looks like yours and I remember also few machine with the same look. It seems to be normal, because that roller is in contact with the transfer belt. So don't worry!
Thanks for the reply. I wiped it with a nice dry, lint-free cloth... and nothing happened. None of it came off. I rotated the roller and saw that there was an even application of yellow and cyan on it also. I set it up and it printed properly, no visible streaking or unintended marking.
Thanks for the reply!
That one is the 2nd Bias Transfer Roller. Normally it shouldn't look like that, but you can try to clean it with a dry cloth.
I started to set up a new WorkCentre 6515. As I removed the tape from the rear, I saw that a roller was covered in magenta toner. There were some other splats here and there, but my questions are:
Is this common?
How did it get there? and,
What is the cleaning process if any is needed?
