Inconsistent Printing Near the End

[icor1031]

I can print an entire page of dark gray, and it's fine--until the end. About 1" from the end, it becomes inconsistent. That would make sense if the ink was low, and then the next print would be inconsistent throughout. But, that's not the case. The next print does the same thing; it looks good until near the end. 

I attached a picture of my print. See the light streak near the left side of the image.

What's causing this, and how do I fix it? It has done this with other print sizes, too.

EDIT: Printer is Pro-100.
