I am sorry but I have no idea how the ink system on the 1390 is designed.  I doubt that the viscosity of the ink is your problem, and likely that aspect is completely beyond your control.  It is what it is and there is no reasonable way to change it.  I can imagine that you will need to figure the correct balance for your system so that ink will flow to the heads, but not run out of them when they are just sitting.  Fo me that required me to find the perfect height at which to place my ink tanks, but you will need to do some experimenting.  Good luck!

As said adjust the height of your inks.

Usually they should be about level with the print head which allows ink to be pulled I  by the printer but not siphon out by gravity. 

Thanks all

I have just tested it, it looks good.
Thank you very much

Hi Trevor,

Your article is too helpful !

You help me, my DIY UV 1390 machine automatically flows out of the print head.  May be due to too dilute ink?
