HP Photosmart C6380 Ink Cartridges

Hi, thanks for dropping us your question. We make sure that our compatible cartridges are consistently manufactured to the highest standards because it makes no sense for us to sell a product that doesn't meet the needs of our customers and one that constantly needs to be collected and replaced due to problems. So we do offer a 3-year guarantee for the quality of the prints, and to protect you against any faults or issues. Whilst I can't promise our compatibles will always be perfect, our failure rate is of the very lowest you will find in the UK and our customers give us great feedback on them.

Hello, I can understand your confusion! There are basically 3 different black cartridges and each of those 3 come in both standard 364 sizes and XL 364 sizes. So the HP Photosmart C6380 printer should have 5 cartridge slots inside it. A slot for each of the Black, cyan, magenta, yellow and photo cartridges. You would need to purchase one of each of those cartridges to fill all 5 slots to get the printer to work and you can choose from either standard or XL cartridges.
