Genuine OEM HP PhotoSmart C6375 Ink and Supplies
The HP Photosmart C6375 has individual HP 564 cartridges for main black, photo black, cyan, magenta, and yellow. The two black inks are separate parts of the system, so checking the complete name is important before choosing either one.
Genuine HP 564 ink at Toner Buzz spans standard and XL singles, a three-color pack, a four-color XL set, and a standard black two-pack. Pick one cartridge for a single low ink, or choose the pack whose included colors best match what needs changing.
