Can You Refill Canon PG-210, CL-211, PG-240, CL-241, PG-245, and CL-246 Cartridges? What About Non-Canon Brands?

Question

How many times can Canon PG-210, CL-211, PG-240, CL-241, PG-245, and CL-246 ink cartridges be refilled? Also, can non-Canon brand cartridges be refilled? I was thinking about buying new third-party cartridges, such as Ejet cartridges from Amazon, because my printer has not been used in a long time and my original Canon cartridges may have dried out.

Answer

Yes, Canon PG-210, CL-211, PG-240, CL-241, PG-245, and CL-246 cartridges can usually be refilled multiple times. These cartridges are integrated printhead cartridges, meaning the printhead is built into the cartridge itself. That is different from printers where the cartridge is only an ink tank and the printhead is built into the printer. Because the printhead is part of the cartridge, the number of successful refills depends more on the condition of the cartridge and printhead than on a fixed number.

In practical use, many people can refill these cartridges several times before they start having problems. Some cartridges may only refill successfully a few times, while others may last longer. The limiting factors are usually dried ink, burned-out nozzles, clogged sponge material, damaged electrical contacts, or worn-out internal foam. If the cartridge has been allowed to run completely dry and the printer kept trying to print, the tiny heating elements in the printhead may have overheated. Once those nozzles are electrically damaged, refilling the cartridge will not restore them.

For Canon black cartridges such as PG-210, PG-240, and PG-245, refilling is usually more straightforward because they contain only black ink. For Canon color cartridges such as CL-211, CL-241, and CL-246, refilling requires more care because the cartridge has three separate color chambers: cyan, magenta, and yellow. If the wrong color is injected into the wrong chamber, or if too much ink is added, the colors can contaminate each other and cause muddy or incorrect printouts.

If your Canon cartridge has dried out from sitting unused, you may not need to buy a new cartridge right away. In many cases, a dried Canon cartridge can be revived. You can add a small amount of water or cleaning solution to soften the dried ink and rehydrate the sponge. This is especially helpful when the cartridge still has a functional printhead but the ink has dried inside the sponge or nozzle area. After rehydrating, let the cartridge sit for a while so the liquid can soak through the sponge and reach the printhead. Then blot the printhead gently on a paper towel. If you see a clean, solid ink mark, that is a good sign the cartridge may print again.

However, you should be careful not to flood the cartridge. Too much water or ink can cause leaking, color mixing, or poor print quality. With color cartridges, it is especially important to identify the correct fill holes before adding any liquid. Adding water to the wrong chamber or overfilling one color can ruin the color balance.

Regarding non-Canon brand cartridges, yes, many third-party or remanufactured cartridges can also be refilled. If you buy an Ejet or another non-Canon brand cartridge, it may still be refillable, especially if it is physically based on the same Canon cartridge design. However, third-party cartridges can vary in quality. Some are remanufactured original Canon cartridges, while others may use aftermarket shells, altered sponge material, or different chip/contact behavior. Because of that, one third-party cartridge may refill well while another may leak, clog, or fail sooner.

The most important thing to check is whether the cartridge has the same built-in printhead style and whether the cartridge body can safely hold more ink. If it has a sponge inside and a refillable chamber structure similar to the original Canon PG or CL cartridge, it can usually be refilled. If it is poorly sealed or made with low-quality internal foam, it may not refill as reliably.

You may also see low-ink or empty-cartridge warnings after refilling. This is normal with many Canon cartridges. The printer often estimates ink level based on usage, not by actually measuring how much ink is inside the cartridge. After a refill, the cartridge may physically contain ink but still show as empty or low. Depending on the printer model, you may need to press and hold the Stop/Resume button for several seconds to bypass the ink-level warning and continue printing. This does not reset the ink level; it simply allows the printer to keep printing despite the warning.

For a cartridge that has been sitting unused for a long time, I would first try reviving the original Canon cartridge before buying new cartridges. Original Canon cartridges often have better printheads than many third-party versions, so if the electrical contacts and nozzles are still good, saving the original cartridge can be worthwhile. Add a small amount of water or cleaning solution, let it soak, gently blot the printhead, and test it. If you get no ink mark at all after soaking, or if the printer gives a cartridge recognition error, then the cartridge may be too damaged to recover.

Common symptoms after refilling include streaky printing, missing colors, faded output, or no printing at all. Streaks usually mean partial clogging or air trapped in the sponge. Missing colors on CL cartridges often mean that one color chamber is dry, clogged, or contaminated. No printing after refill can mean the sponge has not absorbed the ink properly, the printhead is clogged, or the nozzles have been burned out from printing while dry.

So, in short: you do not necessarily need to buy new cartridges just because the Canon cartridges dried out. Many dried cartridges can be brought back by adding a little water or cleaning solution and giving them time to rehydrate. And yes, non-Canon cartridges can often be refilled too, but their reliability depends on how they were manufactured. If you already have original Canon cartridges, I would try recovering and refilling those first before spending money on new third-party replacements.

Addressing printer issues can be a complicated affair because many of these problems require hands-on inspection and testing. For that reason, we are not able to provide remote troubleshooting, individual repair suggestions, or step-by-step support for printer repairs. We do offer an in-person evaluation and repair service through our local diagnostic facility, BCH Technologies Printer Repair Service [https://bchtechnologies.com/printer-repair-service]. Because demand is high, we operate on a first-come, first-served basis, so it may take a few weeks before you are able to drop off your printer. Our services are structured to repair either an entire printer or specific printer parts, with clear instructions on how to proceed. However, we understand that our rates may not be the most economical option for every situation. For that reason, we strongly recommend self-help through online research. A good place to start is YouTube, including our YouTube channel homepage, BCH Technologies on YouTube [https://youtube.com/@bchtechnologies]. Use the search icon next to "About" on the right-hand side of the menu bar to search for specific videos. I receive dozens of questions every day asking whether we have videos on certain topics. Since we have been making videos for the past nine years, it is difficult to remember every single one, so YouTube's search function is usually the fastest way to find the most relevant content. YouTube may also recommend helpful videos from other channels that can assist with your repair or refilling project.

Thanks again for contacting us and for supporting BCH Technologies. I hope this helps you decide whether to revive your existing Canon cartridges, refill them, or move on to third-party replacements only if needed.
