It's to help keep the fuser rollers clean. Supposedly, it helps to repel the toner from the upper fuser roller.

1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

I remember in my first Quest class, our instructor rambled on and on about the importance of a good fuser bias connection. When we ohmed it out it was soon discovered that there was 120 ohms or more between the roller and the terminal. The instructor then had us 'fix' this problem by applying conductive grease to the contact ring (I won't even go into how idiotic this is).
Then one of the students figured out that if you ohm it out while the fuser is rotating (and bias wire disconnected), the resistance drops to near zero.
I've never purposely disconnected the bias contact. I've accidentally left it disconnected, and didn't really notice any difference at the next roller replacement.
Now if you get a short to ground that's another story. It will pull your HVT down, and you'll get all kinds of charge related problems like poor separation (drum wraps), poor transfer, and light to blank copies.

fuser bias and sc069
welshman I beg to differ. If you have access to Canon esupport forums you will find where sc069 was caused by faulty fuser bias on the Ir105.
