HAPPY PRINTING.

That's the same printer I have.

First, make sure the blue "copy" button is lit. Printing is done there.

Then, go to the circle with the checkmark in it and hit the menu, and arrow down to copy papy size and make sure it says "letter".

Click start on your computer, then click control panel, then printers, and make sure Lexmark 8300 series is the default printer and has a green checkmark in a circle.

If all these things are right, you should be able to print a test page and the computer should work fine.

If any one of them are wrong they must be corrected. If you need help on any one of those please write back.

OK, if you can work a volt meter it will help. We want to double check the output of your power supply (P/S) based on the specs written on it , or in the manual. If the P/S is known good, when the printer is turned on, do you hear anything? listen for the faintest fan. If you hear a fan, printer is getting power. if you hear nothing and see nothing, check for a fuse by the P/S plug in somewhere. If you don't see one outside, there is one on a board that needs replaced inside the printer. Check the fuses for continuity. Ill bet its as simple as a bad P/S, lexmark is cheap plastic ****, but still lasts longer than THAT!
