New Cyan 951 Ink Cartridge has manufacturing defect need replacement

[Bad_Ink]

Recently purchased a HP (3) pack 951 Ink Cartridge set, Warranty Date OCT 2026 65020277.  The (C) or Cyan ink cartridge was not recognized when inserted.  Upon inspection against the old cartridge I noticed that there was leftover molded plastic on a portion of the new cartridge when compared to my old cartridge that I was replacing.  This is preventing the cartridge from being recognized.  

How do I get a replacement for this defective cartridge that was part of a 3 pack?

The cartridges do have a warranty, see the document here for information. To get warranty coverage you will need to go to the Contact HP page, then enter the information for your printer.  At this point it will likely say "Manufacturer's warranty has expired"  To the right of this it will say "See details".  Click the "See details" link, which will open another page with more details.  Near the bottom of the text will be a paragraph that says : 

HP has checked your product information, including the product and serial numbers, to determine your warranty results.The legal warranty expiration date is based on the date of purchase, as indicated on your receipt. If you feel these results are incorrect, you may submit a dispute for review. Dispute this >
