VJ1304-Missing nozzles...

[NASIAS]

Hello,
I have a mutoh vj 1304-eco solvent , which I bought on Semtember 2010.A have a missing nozzle in cyan ,from summer ,no matter the head cleaning ,it is always there.I contact the CPI -Greece ,the Mutoh reseller in Greece(because I had a year warranty) and the told me that I did not do the cleaning right and they cannot change the head for me(in the warranty).
Now, I have two more nozzles missing ,in cyan again.:Oops:Any suggestions what I can do to clean the head before I change it?I suspect that something is wrong with the inks(I don't use OEM inks).
Any suggestions would be welcome.

3rd party ink that is out of spec from OEM ink can cause those problems. Especially if the pigment particles are not ground down to the same size. Once a nozzle is plugged for a long time it is almost impossible to get it back. Especially on the DX5 head which is what the ValueJet uses.

However, all problems that I have had with missing nozzles have been directly related to either the head not sealing properly on the capping station, or clogs in the waste/drain tubing under the capping station. You need to clean around your head and capping station 1-2x per week and squirt some cleaning fluid down the cap every time you do this. Also, once a month I like to insert a syringe onto the drain lines (Move the head off the capping station) and gently push/pull cleaning fluid through the lines to rinse and loosen any clogs.

I had two more clogs ,today, in cyan again and I discoved that the waste tubing was cloged,too.Do you think that the inks cause these promblems?
I don't know how to drain ink with the syringe,have you seen a video on you tube or another link to show me the way?
for your response !
