disconnect the printer from electric for 10 minutes, then connect and try.

I will give you step by step instructions:

1. Mae sure that there is paper in the printer, and that all the cables are connected properly. Also make sure that the correct port is selected in contorl panel >Printers> Samsung ML2010> Properties> Ports.

4. If there are pages in the printer queue, delete them. (Double click on the printer, and see if there are documents listed. If there are, delete them)
5. Delete the printer from control panel, disconnect it from the computer, and reinstall it.
6. Install on different USB Port.
7. Change the printer cable.
8. If still not working, install the printer to another computer.
9a. If the printer still not working: Problem with the printer.
9b. If the printer is working: Problem with the USB port on the computer.

Hope this helps

I solved it!! Just hold down the Cancel button and I think it acts as the OK button. The red light will go away and turn green and it will print the odd pages. There you go!

you need to put a new toner

Without knowing what online error, it's not easy to diagnose what happened and how to compensate.

Anyway, try checking the printer cables to ensure they're connected and properly seated. Verify that the paper tray is correctly loaded and the Toner light is OK.
Verify that all printer covers are flush and closed, and check that the printer is correctly connected at the software level (i.e., in Control Panel -> Printers -> (ML2010) -> Right Click -> Properties -> Ports, you have the proper USB socket selected).

Try plugging it in another USB port. Did it stop working, or did it never work? If the latter, then the driver could be incorrectly installed; try removing it and installing again.

Reputable or not, every once in a while you get a bad one (even originals). It's obviously defective. Return for a replacement
