Problem with print outs from printer

I have a CX6400 Epson printer. I am getting gaps in my print outs when I do a test to see where the gaps are, they are in the cyan. I have cleaned the print heads several times and the gap is still there. Is there a way to do a more thorough cleaning on just the Cyan head? Thanks Eastman

    I have tried the solution and it looks like my problem is more extensive than what was given as problem. I will keep soaking the heads & hopefully they will soften. I also need to get full set of new ink too as the old ink could be causing reoccorance of the clog nozzel.

Hey eastman You can do a manual cleaning using some kitchen paper and a little solvent and a small plastic bag. The first thing we need to do is get the head away from its parking position. Switch on the machine and when the head has moved away from its park position, remove the power lead. With the top of the machine open, you should be able to move the print head carriage by hand. Look to the right where the head carriage is normally parked and you should see the pump cap area. It will be a black looking spongy pad covered in ink. Now take a piece of kitchen paper and fold it over a couple times to make a pad approx 3"x1". Now lay this pad over the top of the pump cap and fold the left edge down toward the base of the machine as in image one (the tissue is the yellow bit in the image) Now take a syringe or similar and put some solvent into it. The solvent I use is JR Ink Jet Cartridge flush as seen on ebay and the like. If you have any ammoniated window cleaner like Windex you can use this. Put the solvent onto the tissue making it quite damp, but not totally soaked. Manually move the print head GENTLY back to its park position. The pump cap will try to raise up to meet the bottom of the print head as you move it back. Be careful no to force it or you may break something. What we are trying to do is bring the solvent dampened pad into contact with the print head. Once located, leave the pad for 5 or 10 minutes whilst the solvent does its trick. Now move the head away from park - again being gentle. You should now see the pad is a horrible black lump of mush. Pick it out and put it in the plastic bag ? where a glove or use tweezers or pliers. Repeat the process again but this time let it to soak for just about 1 minute. You should now see the individual ink colours soaking into the pad. If the pad is still black, repeat the process a couple more times. Once you have some evidence of the individual colours you can run a head clean via the driver or printer control panel. Then print a nozzle check sheet and if all has gone according to plan you should have a full complement of lines. This method is applicable ONLY for loss of a few lines on the nozzle check sheet. If you have loss of all the lines in a single or multiple colours, you need to investigate further. It is possible that the pump has failed, the pipes are clogged or something else is causing the problem.

My CX3200 was not printing anything. Read over the advice offered on this site.Tried head cleaning, noted ink was running, because of the subsequent ink collecting below the park station.
Figured heads must be clogged.
Ordered cleaning solvent online. Once it arrived I used isoproply alcohol to clean excessive ink around park station. Used the purchased solvent with Inky's method of underhead cleaning, also injected solvent through the wicks.
Did the trick. All four heads print.

    I used the above procedure (#1) with Isopropyl alcohol on a piece of paper towel and it worked out great! Thank you!

Nothing prints out on paper.

Did you remove the little sticky tabs from each new cartridge? They allow air in, and ink out.

Blank pages are indicative ofdried ink.

If the printer has not been used for a long time ink may have settled and dried in the heads.

You may need to replace the cartridges (IF they are very old) and run several head cleanings if there is no improvement.

I typicall try to print a few test pages to see if some of the color work.

You can leave them in as they will take no harm and the ink will help to push any blockages out from the other side
