Mc235 will not print clearly on the cyan cartridge. have tried cleaning seven or eight times, also changed cartridge but still no luck. can u help? Derek in Ireland

Try reinstall the printer driver again, if still have issue take the cartridges out of the printer then take a paper towel fold it in half and just dab the cartridge on the paper towel to see if it is bleeding ok dab it all over the paper towel to see if it gets better or worse. If it gets better make sure it bleeds good enough to get a solid strip of ink then try it in the printer. if it gets worse take a small plastic container and boil some water then put just enough boiling water in the container to cover the bottom just a touch more then take the cartridge and dip it in and out of the hot water a few times and do the paper towel dip again. The hot water will break up any dry ink in the cartridge head and get it bleeding again. If your cartridge has an electronic board on it use 99% isopropyl alcohol and a Q tip and apply it to the cartride board and don't use the tip use the side of the Q tip and apply a bit of pressure, not only will you clean the contacts but you will evaporate the water that got on the board then wait 5 minutes and try it in the printer. Let me know if you need further assistance Thanks K
