Product Specifications

Why Choose This Pump Motor?

This replacement pump motor without gear head is a cost-effective and reliable solution for maintaining your Roland printer’s ink supply system. It helps reduce downtime, ensures smooth ink circulation, and extends the overall service life of your equipment.

Installed Position & Function

• This pump is typically used in the printer maintenance system for suction, circulation, or waste-ink transfer depending on machine design.
• It is generally installed between the maintenance station, tubing assembly, and waste or cleaning path.
• Stable pump performance helps support cleaning cycles, consistent ink flow, and daily printer reliability.

Recommended Use

• Referenced machine models: SJ1045, SJ1000, SJ1045EX, AJ1000, AJ1045, AJ740, AJ740I, XC540, XR640, XF640, FP740, FJ540, RS540, RS640, VS540, VS640.
• Suitable for industrial inkjet printing environments when the connector layout and tubing size match the reference pump.
• Recommended when suction becomes weak, cleaning cycles become unstable, waste-ink discharge slows down, or the reference pump becomes noisy.

Buying Notes

• Compare pump voltage, tube size, connector position, and mounting method with the model-reference part.
• If your printer has multiple revisions, match the manufacturer part number and maintenance-station layout before ordering.
• For preventive maintenance, buyers often replace the pump together with cap tops, tubes, or wipers when the maintenance system shows wear.

Typical Failure Symptoms

• Weak suction during cleaning cycles, unstable priming, or slow waste-ink discharge from the maintenance station.
• Unusual pump noise, inconsistent cleaning results, or repeated nozzle dropouts after normal maintenance.
• Ink residue around tubes or a maintenance station that no longer pulls ink smoothly during service cycles.

Fitment Checklist

• Referenced machine models: SJ1045, SJ1000, SJ1045EX, AJ1000, AJ1045, AJ740, AJ740I, XC540, XR640, XF640, FP740, FJ540, RS540, RS640, VS540, VS640.
• Match voltage, connector style, tube count, tube direction, bracket position, and overall body dimensions with the reference pump.
• If your printer has multiple pump revisions, compare the old part directly and confirm the manufacturer reference before purchase.

Service Pairing Suggestions

• Buyers often inspect cap tops, waste tubes, dampers, and wipers at the same time when replacing a pump.
• If the machine has been standing idle for a long time, check whether the tubing and capping station also need service.
• Use this part in a industrial inkjet workflow only when the fluid path and sealing arrangement match the reference system.
