sorry it took long ,but i tried to put a new print head in the printer, as it didnt work (printer couldnt recognize the new print head),i have cleaned the old print head with a solution of distilled water and a little bit of isopropyl alcohol (not precisely probably 20 to 30 %), i let the bottom of the print head overnight in the solution and injected with the syringe in the morning more of the solution in the color causing problem(light grey), as seen in the video. put the print head back in the printer did a couple test print to make sure all the alcohol would be gone. Then i printed little prints.The prints seems to have improved but still seeing little lines here and there but need a magnifying glass to see them. I am going to run bigger prints today and will post results. Conclusion I think it works didnt seem to have damaged anything, may need to do another process with more injection cleaning with the syringe into the print head. i am new at this tell me if everyone can see my answer and do i have to close the question? and how?

That is hard to say. I have gently cleaned print heads with a soft cloth and Isopropyl Alcohol. I have never use chemical cleaners as that could seep into the head and ink.

My own experience is that the only cleaning that can be done on an inkjet printhead likely to remedy clogged jets is to bleed the printhead overnight.

This works about 1/4 of the time for badly clogged jets.  Mix 100 ml distilled water, 20 ml isopropyl alcohol, one drop liquid dishwashing detergent.  Fold a paper towel in quarters and put it on the bottom of a flat-bottomed glass vessel.  Pour in enough bleeding solution to fill 1 cm deep. Then gently place the printhead, jets down, on the paper towel.  Wait overnight.  Next day, remove the printhead from the bleeding solution and replace it in the printer.  If the situation is improved but not all jets are clear, bleed once more.  If the jets are still clogged, a new printhead is required.

Side note:  There are various "head cleaning" cartridges sold as being able to clean severe head clogs.  A little reflection prompts the question:  If the ink passages are clogged, how is the solution going to get to them?
