4.6 Flushing System
This system provides solvent flushing for all print heads. A solvent
pump is provided to pump the solvent from the solvent bottle to ink tank
manifold then it is distributed through the ink tank manifold. The manifold
valve can be turned individually to appropriately enable the flow of solvent
flush to each particular print head. The solvent pump is turn-on/activated by
a toggle switch that provides the 24Vdc to the solvent pump unit.
The solvent flushing can be done to all print heads at the same time or
only print head at one time by closing and opening the ink tank valves
accordingly. Solvent flush is necessary if there is stubborn clogging in the
print head nozzles or when the machine will not operate over night
Notice: If had to replace the ink , all ink line must be flush to clear!.
