A:AnswerThere are two 564XL black cartridges used in HP PhotoSmart printers.
The narrow one has a symbol that looks like a bow tie, the thick one has a pentagon (not a hexagon). The box for the narrow one will be marked
"photo" and has a symbol resembling a camera. The box for the thick one does not have anything, just 564 XL. Hope this clarifies it for you.
A:AnswerIt's important to note that the ink expiration date is NOT the date stamped or printed on the ink supply. Rather, the printed date on all HP inkjet supplies is the “Warranty ends” date. To determine the ink expiration date on a particular supply, the consumer needs to consider three factors: the ink supply, its warranty date, and the date on which the cartridge is initially installed; however, most HP printers will stop using the ink based on the following schedule: 24 months after the “Warranty Ends” date, or 30 months after the ink cartridge is installed, whichever comes first.
