Installation Tips
- Power off printer; cap the heads and clamp ink lines.
- Swap the pump, ensuring correct “IN/OUT” hose orientation.
- Prime/charge ink and check for uniform negative pressure.
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: XR640, XR-640, SJ-1045, SJ-1000, SC-540, XC-540, XJ-540, RS-640, VP-300, SP-300, VS-300, RA-640, RE-640, LEC-300, FH-740.
- Suitable for solvent 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: XR640, XR-640, SJ-1045, SJ-1000, SC-540, XC-540, XJ-540, RS-640, VP-300, SP-300, VS-300, RA-640, RE-640, LEC-300, FH-740.
- 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 solvent workflow only when the fluid path and sealing arrangement match the reference system.
