Original Roland SOLJET EJ-640 / Texart XT-640 Valve Drive Board – 6703524030

Roland part number 6703524030 is a valve drive board for the SOLJET EJ-640 and the Texart XT-640 64-inch production printers. This is a genuine, original Roland part – not a copy or compatible replacement.

On these machines, electrically operated valves open and close the ink path during ink supply, filling and cleaning. The valve drive board switches the valves on instruction from the ink system. When it fails, you may see ink supply errors, colours dropping out because ink no longer reaches the heads, cleaning or initial fill sequences that stop with an error, or ink flowing when it should not.

Compatible models: Roland EJ-640 and XT-640. Because these printers often run long unattended jobs, a reliable valve drive board is important to avoid ink starvation halfway through a roll. If only one colour is affected, check that valve and its cable before replacing the board.
