I have authentic HP951XL unused print cartridges from my previous HP8610 printer. When I try to put them in my HP8615 (which also uses 951XL cartridges) the machine says they are intended for an earlier generation of printer but that if they are authentic I should contact HP support. What do i need to do to get them working? Any help would be appreciated!
