I'd greatly appreciate some help with a little troubleshooting.

I own a Samsung ML-1710 Laser printer. I like it a lot. It's inexpensive and it's small, so it's good for someone like me who doesn't print all that often.

I'm having a problem, which can be seen in the attatched image. When I was just printing normal documents, I couldn't quite see what it was doing, but I knew some of the text was lighter than the rest. So I tried printing out a large black square and got the following:


{the right side is the top edge of the page)

Any idea what's going on? There isn't any sort of toner save function enabled, and even if there was, I've tried turning it on and off and nothing seemed to change anyway.

Now that I look at some of the other documents, though, I don't think that the toner problem is limited to the area in those printings, because in other documents, it seems to be occuring all over the page, in random places. I can't figure out why it would be that way, then print three identical pages like the ones above.

Any ideas?
