right ink number but wont fit

[Mrf4rbm]

I have purchase 4 564 black inks and none will fit in slot 1 but it fits in slot 5. Slot 5 is bigger then slot 1 in width. I really need help. Slot 5 has an octagon on top of it and i need an triangle to triangle type size. Tops of triangle are facing each other.

@Mrf4rbm, Welcome to the HP Support Community!

This model printer uses 5 ink cartridges. Slot 5 is for photo black ink cartridge only. Each ink cartridge should be inserted in its particular slot. Match the symbols or look for the color code.

To know how to insert ink cartridges in the printer, refer to Replacing Cartridges for the HP Photosmart 7510 and 7520 e-All-in-One Printer Series document.
