David,
I have seen the problem you described, I use a different supplier for my cartridges than you do so it is not an issue with one manufacturer.
There is a buildup of residue on the roller that causes the small dots on your paper.
Take your cartridge out of the machine and swing the cover away from the roller (there is a latch to release the cover) - take a piece of cloth (like an old t-shirt) and using your thumb wipe the toner off of the roller until you feel the rough surface on the roller, then advance the roller and do the same until you have worked your way completly around.
This should get you back in business.

Thank you John.
I knew that procedure would need to be done occasionally, to combat a laser printer's version of banding.
I didn't think I would run into that problem so soon, but my black cartridge does see the most use.

To take John's advice one step further, I was advised by an HP certified technician (aka my better half) that cleaning the roller should be done with a piece of standard bond paper, rolled into a tube lengthwise. Open the cart so you can get at the roller, and using a downward sweeping motion like you were honing a knife edge, run the tube of paper down the roller a section at a time to remove any build-up. Move the roller occasionally so you can get all the way around the surface. This should leave no stray debris on your roller, which could add to your problems in the future.
Keeping your printer clean, inside and out, is also a good idea. A small soft brush and some canned air used carefully can be quite handy.

Tam,
That makes sense. Just as performing a physical head cleaning of ink jet printheads should be done with a non-fiberous sponge, as not to introduce foreign debris to the heads.
Thanks for the tip and say hello to your better half (Jeff) for me. :-)
