6000006825 - ASSY PUMP

Sub pump maintenance assembly – 6000006825

The Sub Pump (6000006825) is a central part of the maintenance system on Roland Soljet printers. Connected to the capping station, it draws ink from the printhead nozzles during purge, cleaning and priming cycles. Its U-shape internal structure with a reinforced tube resists eco-solvent ink wear and gives a constant, reliable suction pressure. Complete assembly — the current Roland version, officially replacing 6000006292, 6700319010 and 6000005297, fully compatible without modification.

Function

• Draws ink from the nozzles during purge and automatic cleaning cycles
• Generates the negative pressure to prime the ink circuit after a cartridge or head change
• Evacuates waste ink to the waste tank via the capping station
• Keeps the printheads in optimal condition between prints
• Ensures reliable scheduled maintenance (cleaning, medium/powerful cleaning)

Signs of wear

• Ineffective cleaning cycles — persistent clogged nozzles despite several cleanings
• Suction pressure drop at the capping station
• Leaks, weeping or ink marks around the pump
• Abnormal noise (grinding, knocking, straining motor)
• Ink overflow in the capping station or waste collector
• Peristaltic tube wear (cracks, flattening, loss of elasticity)

Replacing this part restores the machine to proper working order.
