How to Refill HP 902 XL Cartridges and Choose Between Dye and Pigment Inks

Question:
I have a 902 XL cartridge for black and 902 cartridges for magenta, cyan, and yellow. Which refill kit should I use for these cartridges? Also, what kit do I need for a bulk ink setup, and should I use pigment or dye ink for my printer?

Thank you for contacting us at BCH Technologies. I sincerely apologize for the delay in responding to your inquiry.

To answer your questions in detail:

Refill Kit for HP 902 XL Cartridges

We currently do not offer a specific refill kit for the HP 902 XL cartridges because most people simply flip the cartridge over and drip the ink onto it. Watch our video guide on how this method works here: Watch on YouTube [https://youtube.com/N7Y1nk-D5cc].
We offer transparent casings if you're more experienced and would like to transplant chips. These casings are available here: HP 902 Casing [https://tinyurl.com/yc2optw5]. We also have a video tutorial to walk you through the process: Chip Transplant Guide [https://youtube.com/2DJQLUeTBfA].

Bulk Ink Setup (Continuous Ink Supply System - CIS)

You must install a continuous ink supply system (CIS) to switch to a bulk ink system for cost efficiency. This requires setting up a barometric external ink tank. You'll also need to drill holes in the back chamber of each cartridge and seal the air hole at the front. This setup allows continuous refilling, reducing the frequent purchase of new cartridges. It can be a bit complex, but it's a worthwhile solution for high-volume printing.

Should You Use Pigment or Dye Ink?

You asked about whether to use pigment or dye ink. The good news is that your printer can handle both types, and here's the breakdown:

Switching Between Ink Types

Switching from dye to dye ink is not an issue. However, mixing dye and pigment inks is not recommended for prolonged use because the different base solutions can cause clogging. If you need to switch, use up as much of the remaining ink as possible before changing the ink type, and print several pages after the switch to flush out the old ink. You can find more details about switching ink types here: Switching Ink Types [https://support.bchtechnologies.com/hc/en-us/articles/200555919].

 

You can safely use dye ink in a pigment ink printer, but using pigment ink in a dye ink printer requires more manual cleaning. Once you decide which ink to use, it's essential to stick with one brand to avoid clogs that could arise from switching between different third-party inks. If you experience any issues, BCH Technologies offers cleaning solutions that can help, such as our clear dye base and clear pigment base. You can find them here:

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. As such, we cannot provide remote troubleshooting or support for printer repairs. However, we do offer in-person evaluations via our local diagnostic facility. You can learn more about our services here: Printer Repair Service [https://bchtechnologies.com/printer-repair-service].
