Getting Fingers Dirty
Hi all
Its not all success in this game. Recently worked for two days trying to unclog a canon iP3500 print head that was giving very poor fuzzy and pale prints. Used a mix of 20 parts hot water, 2 parts vodka, and 2 parts household ammonia which has always worked brilliantly in the past in unclogging various printer items. Tried everything from soaking overnight with print heads sitting on a damp paper towel to actually manufacturing a multi use cleaning cart from an old flushed out ClI-8. I drilled a hole over the ink tank (not over the sponge compartment) of a size to take a syringe without needle of a size to make the syringe outlet a tight fit in the hole. All other holes (but not the main outlet feed hole or breather channel) were filled with hot melt glue . The cart was then filled with cleaning solution then held tightly over each of the colour inlet nozzles inside the head in turn while a syringe full of the same fluid was inserted tightly into the hole in the ink tank then injected with a fairly firm pressure. After treating the nozzles in this way the cart. and syringe were filled with hot water and the whole procedure repeated. After a few attempts at this alternating between water and cleaning fluid I eventually gat a good steady fine stream of water from each of the nozzles. Great I thought but another nozzle check print showed no improvement. New printhead needed from one of my spare 3500's . Image of nozzle check for all to see.
I refill using the german method and use top quality inks from inktec.
What is anoying is that the printer is not yet a year old and the failure seems to be electrical rather than a physical clog. Any other ideas would be greatfully received.
