HP6L - dirty printing

I have been re-cycling previously printed sheets. Now, when printing on clean sheets, my pages are speckled with black dots. Suggestions?
Well its probably a toner or fuser issue. You could try a half test. Print a page. Once the paper has left the tray and is in the middle of the printer open the door and see if the dots are on the page before its fused. If so you probably have a toner issue if not you probably have toner build up on the fuser pressure roller. Toner build up on the pressure roller will probably give you specks on the top side and bottom side of the paper. If the dots are equally spaced/repeat vertically on the paper then you have a roller issue measure the distance from one to the next and it will give us the diameter of the roller causing the issue. To me it sounds like toner from the recycled paper is coming off and sticking to the pressure roller. When it heats up the fixing unit is picking it up and putting it on your new paper. So most likely you will have to clean the pressure roller. The pressure roller is orange is color and under the fuser fixing film is you remove the front door and tilt the machine up you should be able to see it and check for toner build up.

Thanks for your response. Yes, the dots are equally spaced and repeat vertically on one side of the paper; the interval is 3 inches. I see the orange roller, but access appears difficult and I have not checked for toner build-up. So, what is the "fix"?

Did you do the half-stop test as suggested and determine that the problem was in fact the fuser and not the toner cartridge? Don't go after the hard stuff, without first eliminating the easy stuff.

Moe: Thanks for the excellent advice. I swapped out the old toner cartridge and inserted a new one. Problem solved!
