1) Press the ink button, then the print heads will move to the replacement position. Take the power cable out.
2) Remove the cartridges from the printer.
3) Draw some cleaning liquid from the bottle using syringe.
4) Use the tube connecting to the syringe to cover one ink inlet.
5) Syringe 1-2 ml cleaning liquid into the ink inlet.
6) Repeat 3-5 to the other ink inlets.
7) Install the cartridges back. Dip the ink inlets in this cleaning liquid about 8 hours. Please do not turn the power on during these hours.
8) Turn on the printer and run the head cleaning and nozzle test.

If the print head is clogged and you could not make it work, please do as follows:
This is for heads that are too blocked to be sufficiently cleaned by the process mentioned on the first page. It involves forcing cleaner through the channel and out the print head. This should be done only if the first process fails. Draw up about 3 cc's or ml of solvent in the syringe with the tubing attached. Place the tubing directly ON the head ("head" as in the entrance to the channel mentioned above). Make a tight seal by pushing down on the syringe and then force the solvent through the channel and out the print head.

Using a old ink cartridges or Refillable cartridges:
Another way is to inject the cleaning fluid into a used or refillable ink cartridge (making it into a cleaning cartridge) and then just run a few head cleanings then print a few pages of large pictures. Once you are finished cleaning just remove the "cleaning cartridge" you made and place it into a zip lock bag until the next time you need it. This method does work but is much less effective.
