You're leaking toner somewhere inside the printer. If you've recently changed cartridges...

otherwise it might be time for a good cleaning, because once unfused toner starts moving around inside a printer you have to clean every roller in the paper path.

1. Turn off the machine's power switch. Unplug the telephone line cord first, disconnect all cables, and then unplug the power cord from the AC power outlet.

2. Lift the document cover.
In the ADF unit, clean the white bar (1) and the scanner glass strip (2) under it with a soft lint-free cloth moistened with water.

Note

In addition to cleaning the glass strip with a soft lint-free cloth moistened with water, run your finger tip over the glass strip to see if you can feel anything on it. If you feel dirt or debris, clean the glass strip again concentrating on that area. You may need to repeat the cleaning process three or four times. To test, make a copy after each cleaning.

3. Plug the machine's power cord back into the AC power outlet first, and reconnect all cables and telephone line cord. Turn on the machine's power switch.

check the wheels that pick it from the tray.
If they feel smooth, try to put some tape on them and rip it back off.
This cleans the wheels. Also try a new pack of paper and check if it\'s set to plain paper and not to heavier or coated paper
