Q: Can I find a refill solution for HP 67XXL cartridges for my HP 6400 series printer, covering both color and black inks?

A: Absolutely, we have got you covered for refilling both color and black HP 67XXL cartridges for the HP 6400 series printers. While BCH Technologies does not sell original HP cartridges, we provide comprehensive refill kits that are perfect for your needs. To guide you through the refill process, you can refer to our instructional video here: https://youtu.be/DvtNz_Y6D-g. This video, though demonstrated with an HP 67 cartridge, is applicable across the HP 6x series including HP 61, 62, 63, and 64, showcasing the universal refill method.

It's important to note that the designation XL and XXL refers to the volume of ink the cartridge can hold, with XL and XXL cartridges containing more ink thanks to a larger sponge. This means that the refill process is identical across these variations; they just allow for more ink storage. Given that these cartridges integrate the printhead, they're designed more for convenience than longevity, without complex anti-clogging features found in permanent printheads. Therefore, to minimize clogging, we recommend using dye-based ink, which is less prone to clogging and easier to unclog.

For beginners, our First-timer Kit (EZ30T) provides all the necessary tools for 5-10 refills and includes a set of priming tools to help ensure a smooth refilling process. This kit is available at https://bchtechnologies.com/first-timer-ink-refill-kit-for-hp-inkjet-printer-cartridges-60-61-62-63-64-65-ez30-t, with additional guidance provided in this YouTube video: https://youtu.be/s19ypQ0r2Dk. Remember to save the priming tools for future refills; you'll only need to purchase additional ink, recommended here: https://www.bchtechnologies.com/refill-ink/refill-ink-for-hp/standard-600-ml-4-color-refill-ink-for-hp-kd600x-ch.html. Additionally, for troubleshooting common E1 and E0 errors encountered with HP 67 cartridges, check out https://youtu.be/ipueD4xutk4.

If you encounter any priming issues or lack a priming clip, a household vacuum can be adapted as a workaround to prime the cartridges effectively.
