Toner gathering on roller causing line

[Phasergun]

I guess I could try that. I'm not sure there any techs nearby. I'm just wondering if I only need to replace that roller. I only need to know two things:

• What is that roller called?
• Can I swap it with another roller to test if that is the problem?

It might be an obvious fix.

Hello Phasergun, 

I see no one has responded to this post yet with a permanent solution. So, at this point I would recommend contacting your local Xerox Support Department to speak with a Product Specialist for more assistance. Please call 1-800-835-6100.

I know this printer is getting a little long in the tooth, but it is seriously the best printer I have ever had. A consistent workhorse that has never let me down.

Recently it has started printing a black line across the page. Yeah, I know, get in line, everybody has this happen. But the thing is, I know WHY it is happening, I just don't know how to fix it, permanently, only temporarily.

(see photo) When I pull out the black roller, I can clearly see the black toner pooling up on the roller. If I carefully vacuume/clean this off, line is gone, for a while. Maybe 10 prints later, it's back. Same reason.

What is happening here?

Toner gathering.
