Can I repair the internal components of the HP Deskjet Ink Advantage 2300 myself?
No, there are no user-serviceable parts inside the printer. All repairs should be referred to qualified service personnel. If the printer is not operating normally, refer to the help files available on your computer once the software has been installed. (Page 7)
