Can You Use HP Ink Refill Kits for Canon Cartridges Like PG-240, CL-241, PG-245, and CL-246?

Question:
I recently switched from an HP printer to a Canon model and noticed that refill kits for Canon cartridges, such as PG-240, CL-241, PG-245, and CL-246, seem very model-specific. Why is that the case? I already have an ink refill kit I used with HP cartridges-can this same ink be used for Canon cartridges, and if not, what makes them different?

Answer:

The main reason refill kits appear to be model-specific is not because of the ink itself, but because of the priming clip design used with the cartridges. Different cartridge families-such as HP versus Canon-have different physical shapes, nozzle plate depths, and port placements. The priming clip is the tool that helps you draw ink into the cartridge, remove trapped air, and create the right seal during refilling. For Canon cartridges like the PG-240, CL-241, PG-245, and CL-246, the clip needs to be taller to fit their design. An HP priming clip usually won't seat properly on Canon cartridges, which can lead to poor suction or air leaks.

As for the ink itself, in most cases, the liquid ink is interchangeable, particularly for standard dye-based colors. However, the key challenge lies in how it is delivered into the cartridge. If the wrong clip is used, you risk incomplete priming, trapped air bubbles, or even damage to the nozzle plate. That's why refill kits are packaged with model-specific clips-they ensure the proper fit and function during the refill process.

So yes, you can use the same ink from your HP refill kit inside Canon cartridges, but you will need the correct Canon-compatible priming clip to make the refill successful. Without it, you'll likely run into priming issues that prevent the cartridge from functioning correctly after refill.

Addressing printer issues can be a complicated affair due to the hands-on nature of the problems. For this reason, we're not able to provide remote troubleshooting, suggestions, or direct repair support. However, we do offer an in-person evaluation and repair service at our local diagnostic facility (https://bchtechnologies.com/printer-repair-service). Because of high demand, this service is provided on a first-come, first-served basis, and it may take a few weeks before we can receive your printer for drop-off. Our repairs can target either the entire printer or specific components, with clear instructions on how to proceed. That said, we know our service rates aren't always the most economical, which is why we strongly recommend supplementing with self-help resources. A great place to begin is our YouTube channel homepage (https://youtube.com/@bchtechnologies). You can use the search icon next to "About" to find specific tutorials-I've uploaded hundreds of videos over the past nine years, and the search function is the fastest way to locate what you need. YouTube may also recommend other creators' videos that could provide additional insights.

Thank you again for your thoughtful question and for your continued support. We truly appreciate your engagement and wish you success in keeping your Canon printer running smoothly.
