Editing HP Ink Cartridge ID Chip Swap Guide (section)

===Required Materials and Tools===

In order to perform this hack, you need spent OEM or third-party compatible cartridges specific to your printer model. These can be sample cartridges, standard cartridges, XL cartridges, or any mix of the three - they just have to work in your printer and match the color of your replacements. If you do not have any on hand, you can generally buy empty cartridges off eBay.

As for tools, you're going to want a hobby knife (or anything with a small tip that can be used for gentle prying), a rotary tool with a cutting disc, and thin double sided tape (or some other weak temporary adhesive). Gloves and eye protection are strongly recommended.

In this example I am going to be using a yellow 902 XL cartridge as my donor and a yellow third party 564 XL cartridge as my recipient. Note how both cartridges are dimensionally identical, despite the difference in name.
