Solvent printer head problem again. Uniform Cadet
For those that read my posts in the “Orange jet V Versacamm” thread then here’s a sorry update.
After having four head changes in the first year down to banding, we changed the ink set in February over to Citrosol milder inks
and here we are less than three months in and guess what? Yes, more head problems.
This time the black has started banding and gives a rough edge to the prints like overspray. Have done several cleans as the engineer suggested two weeks ago, and let the heads soak. We can only do this for about twenty minutes as it syphons ink up into the other colour tubes. The symptoms are exactly the same as all the previous times, with very prominent lines through prints on lower passes but fine on the highest amount of passes and resolution. If you look at the pictures posted in the above post then it’s exactly the same but this time in black.
We thought the milder inks would cure this but apparently not. Can anyone suggest why this machine eats the heads?
We use it every day to keep the ink flowing but have not done a massive amount of large prints, mainly labels and 3′ x 2′ size prints. This machine is now 15 months old.
Waiting for a return call from B&P light brigade.
I will let you know the outcome.
