I have a HP Officejet J5740 All-in-One Printer, but noticed that there is no information on it's cartridges (C8335-Black#74 and C8337-Color#75).  Does Universal support these ink cartridges or is

there something different about it's ink?  I'm sure there shouldn't be a problem with HP's ink and it should be the same as other HP ink.  Universal does have information on refilling Cartridge #99 for my

computer, which is used for extra fine photo printing.  Does Universal have information on refilling these cartridges?  Would help so I know what fill holes to refill at.
