Question:
I received the ink this morning, thank you. The package instructions say to go to BCH support and access the refill manual by cartridge number. My HP cartridge is 910 or 3YI61A, but I do not see this cartridge number listed. Can you point me in the right direction?
Answer:
For your HP 910 (3YI61A) cartridge, the correct refill instructions are included in the same guide that covers several HP cartridge families, including 564, 902, 920, 910, 934, and 935. You can access the step-by-step manual here: How to Refill OEM HP 564/564XL/902/902XL/920/920XL/910/934/935 Cartridges (https://support.bchtechnologies.com/hc/en-us/articles/200989715-How-to-refill-OEM-HP-564-564XL-902-902XL-920-920XL-910-934-935-Cartridges).
This guide provides detailed instructions, including where to drill the refill hole, how much ink to use per chamber, and tips to prevent overflow or chip recognition issues. Since the HP 910 cartridges share a similar design with the 902 and 920 families, the refill procedure is essentially the same.
Important Notes for HP 910 Refills:
-
Always use the correct ink formulation for HP pigment and dye channels-mixing them can damage print quality.
-
Refill slowly to avoid introducing air bubbles, which may cause streaking or "missing nozzles" in prints.
-
After refilling, reset or bypass the cartridge's ink monitoring if your printer displays low-ink warnings.
Addressing cartridge refills can sometimes be tricky due to differences between printer models and chip behavior. That's why we can't provide remote troubleshooting beyond written guides. However, we do offer an in-person evaluation and repair service (https://bchtechnologies.com/printer-repair-service). This service is first-come, first-served and may take several weeks due to high demand. For many customers, self-help is the most efficient route, and a great place to start is our YouTube channel (https://youtube.com/@bchtechnologies). Use the search function next to the "About" tab to find videos on HP cartridge refills, or explore YouTube's suggested content for related tutorials.
