PG-245 Cartridge Refilling: Tips to Avoid Clogging and Improve Ink Flow

Q/A:

Q: Have there been changes to the PG-245 cartridge's foam pad by Canon, affecting ink refilling with a 10 gauge transfer needle, leading to clogs and disrupted ink flow?

A: I understand your concern with refilling the PG-245 cartridges and the issues you're facing with the foam pad clogging the needle. While I'm not aware of any specific changes Canon has made to the sponge within the PG-245 cartridges, the challenges you're experiencing might be related to the refilling technique rather than the foam's properties. When refilling, it's common practice to insert the needle deep into the cartridge to release ink closer to the ink intake, minimizing air bubble formation. However, I prefer a different approach where I release the ink at the top of the sponge, allowing it to absorb the ink gradually. This method also helps in avoiding air bubbles, which can naturally de-gas after letting the cartridge sit for a few minutes post-refilling.

Additionally, utilizing a priming tool can be highly effective in removing any trapped air bubbles, ensuring a smooth ink flow when the cartridge is used. It's also crucial to avoid letting the cartridge dry out completely, as this can introduce air into the system and lead to further complications. The consistency and condition of the sponge can indeed vary, but by adapting your refilling technique and ensuring the cartridge is never fully depleted of ink, you can mitigate many common issues associated with refilling.
