Please read all precautions carefully before starting.

1. Power off the device before operation.

2. Ensure ink tubes are reconnected correctly during reinstallation.

3. Remove the cleaning fluid cartridge first. If the cartridge is not removed, cleaning fluid will leak when the tube is disconnected.

4. Waste ink is corrosive. Always wear gloves when handling.

5. Before cutting any ink tube, take protective measures to prevent liquid from contacting skin, equipment, or the work surface.

6. During reassembly, check that all exposed cables and ink tubes are properly routed and seated.

7. If replacing multiple pumps, replace them one at a time to avoid mixing up ink tube connections.
