Canon MG3620 CL-241XL Yellow Prints Orange After Refill: What Overflow May Mean

Question:

After refilling an original Canon CL-241XL color cartridge in my Canon MG3620, yellow prints orange. Yellow ink overflowed as soon as I tried to refill it, so I am unsure how much entered the cartridge. Nozzle checks and cleaning have not fixed it, but a second original CL-241XL prints yellow correctly in the same printer. What should I check?

The good-cartridge comparison is useful: it points toward the refilled cartridge or its ink path rather than a general MG3620 setting. Orange where yellow should appear can be consistent with magenta mixing into the yellow chamber or ink path, but the description alone cannot establish how that happened. A wrong refill opening, a contaminated needle or bottle, or ink moving between chambers are possibilities. The immediate overflow could also reflect overfilling, poor absorption by the sponge, or a blocked vent; it does not prove that the cartridge is empty or that overfilling is the sole cause.

Stop adding ink for now. Keep a leaking cartridge out of the printer and keep ink away from its electrical contacts. Do not force ink or cleaner through it with a syringe or repeat cleaning cycles just to test the color. Canon’s MG3600-series troubleshooting guide [https://ij.manual.canon/ij/webmanual/Manual/W/MG3600%20series/EN/UG/UG_Myprinter_Trouble2.html] can help you compare nozzle-check patterns, but it cannot identify the refill opening or the condition of this particular cartridge.

If you already have nozzle-check images from both cartridges, compare the yellow and magenta sections. A clear top photo of the refilled cartridge showing the opening used for yellow, plus the yellow bottle label, can help verify color placement. If the sponge was removed, say so, because the fill behavior and safe next steps differ from an original sponge cartridge. Do not drill a new hole or assume a refill volume from a different cartridge model. Depending on what the comparison shows, the cartridge may need careful correction or replacement; neither outcome is confirmed yet.
