Since the error appeared right after refilling the yellow tank, the printer may not be detecting the yellow ink system correctly. Check that the yellow tank is actually filled to the proper level and that the tank cap/vent is closed or positioned correctly according to the manual.

Also check for any spilled ink around the tank and make sure there isn't an air/ink-flow issue. Turn the printer off, unplug it for about 60 seconds, then reconnect it and check again. If the yellow tank symbol and red alert keep flashing and the printer still won't function, let us know the exact light pattern or share a photo of the printer's control panel. That would help identify the specific error.

All tank caps are properly closed. No spills. Tanks' level seems OK. Tried to turn the printer off on again and also tried to and unplug it for several hours. Nothing changes...WhatsApp Image 2026-09-09 at 18.22.44.jpeg
