6000006825 - ASSY PUMP

Sub Pump Maintenance Unit – Roland Soljet – Part Number 6000006825

The Sub Pump (Sub Pump / Press Pump) reference 6000006825 is a central component of the Roland Soljet printer maintenance system. It is connected to the capping station and ensures ink is drawn from the print head nozzles during purging, cleaning and priming cycles.

Designed with a U-shaped internal structure, this pump is fitted with a reinforced tube specifically pressed to withstand wear and corrosion from solvent and eco-solvent inks. This design ensures a constant and reliable suction pressure, which is essential for the proper functioning of maintenance cycles and for preserving the health of the print heads.

Supplied as a complete assembly (Assy), part number 6000006825 is the latest version currently available from Roland and officially replaces the obsolete part numbers 6000006292, 6700319010 and 6000005297. It is 100% compatible with printers previously fitted with these earlier versions, without the need for any mechanical or electrical modifications.

Function

• Suck ink from the nozzles during automatic purge and cleaning cycles
• Generate the negative pressure required to prime the ink circuit after replacing a cartridge or printhead
• Drain used ink to the waste tank via the capping station
• Maintain the print heads in optimal working condition between print jobs
• Ensure the regularity of scheduled maintenance operations (cleaning, medium/powerful cleaning)

Possible symptoms of wear

• Ineffective cleaning cycles — persistent nozzle blockages despite multiple cleanings
• Drop in suction pressure at the capping station
• Leaks, seepage or ink marks around the pump
• Abnormal noises during operation (squeaking, clattering, motor straining)
• Ink overflow in the capping station or at the waste collector
• Error messages related to the maintenance system or ink circuit
• Wear on the peristaltic tube (cracks, flattening, loss of elasticity)

Replacing the Sub 6000006825 pump immediately restores the reliability of the maintenance circuit, prevents repeated clogging of the print heads and significantly extends the service life of these critical components on your Roland Soljet printer.
