Is there any sign of Cyan coming through the CO channel.Īssuming there is, use a cotton-bud/Q-tip to mop up the CO channel then move the printhead to another clear (but soaked) part of the kitchen towel and repeat with the mop up operation. Pay particular attention to the Cyan and CO channels. Then gently press the printhead down into the kitchen towel such that the content of the printhead channels is forced back to the inlet mesh.
Next, remove the printhead, soak a piece of folded kitchen towel with either a cleaning solution or distilled/deionised water (definitely NOT tap water). Check the outlet of the PGI-72CO cartridge for any sign of cyan (or anything other than clear fluid). When they leak there is air in it, this should not happen, there are posts how to solve this. PS: check all your carts, in particular the cyan, for leaks, and clean the printhead around the ink inlets. Repeat a few times, you should see the pads becoming white. You don't need to disassemble the printer, just position the printhead in the middle as for changing ink, and spray some deminarized water (a used for ironing) with a syringe on the pads (they are of ceramic material).Ĭlose the lid and wait until the whirring stops, shut down and restart the printer and verify if all the water has disappeared. I would start by rinsing the parking pads (the rubber cups at the right where the printhead rests). What kind of CO do you use (most 3th party are rather poor IMO), maybe you should try an OEM one. How does the outlet maze of the CO cart looks like ? Seems Cyan ink contaminates the CO channel.
