How to change a toner on a HP PDC2410 all in one Printer? -

I have a HP PSC2410 all in one Printer. It is not printing properly. When it prints is is all smeared. I have changed the Ink cartridges but have been told I need to change the toner. How do you do this?Thanks.

Though I saw once reference to a quot;tonerquot; for this printer on the website. It does not have a toner cartridge. Toner is used in Laser printers. The manual makes no mention either: http://h10032.www1.hp.com/ctg/Manual/bpu… Check this out: http://h10025.www1.hp.com/ewfrf/wc/docum…
