DX2 head cleaning question

[Dennis422]

I recently bought used Falcon Outdoor 48 inches.
The tech changed both print heads but it seems that I'm getting streaks through the print while printing. I posted about it already once and I have tried changing the heat settings and tried countless profiles, same thing is happening.

What would be the best way to check if I have some clogged nozzles? When I do a nozzle check, it comes out streaky, in Magenta, light magenta and black ink (I believe that is on one head).
Should I take the heads out and soak them in cleaning solvent for a while and then try to use syringe to try to blow out the nozzles or I should try the trick with cleaning cartridges that you guys discussed on this thread (I know it was for a Roland printer, but principal should be the same).

Thanks in advance.

if the test print already has dropouts or reflections then it has nothing to do with settings or profiles.

1] Check if the wiper is clean and use some cleaning solution on swabstick to clean it. Or order new wiper rubbers. They are really cheap.
2] Use some lint free clothing and drain it in the cleaning solution and park the head on it for a while. This might your foam in the maintenance station to swell! So take care that after this the foam does not touch the head and you get crosscontamination. Repeat and see if more nozzles are now free.
3] Place the head in the middle and put a thin cloth underneath it. Remove the dampers from the head and fill a syringe with cleaning solution and slowly press the solution through the head. Leave the solution sit for a while in the head. Now slowly also pull the solution from the head. If you see debris clean the syringe and fill it again with fresh solution. Dont push back the debris. repeat untill there are no debris anymore floating when pulled back in the syringe. In the end push one syringe of cleaning solution 5 ml through the head and let it sit for a few hours.
If this does not clear the blocked nozzles take the head out and put the head in cleaning solution in a ultra sonic cleaner.
Also clean and check all other lines from the pump to the waste bottle.
If they are blocked and the pump does not work correct it will not suck the blocked nozzles.

Cleaner solutions come in different mixage and strength. The more they odor the stronger they are I found out.

let us know the progress.
