Questions about this item

How does the ink pump affect print quality once installed in a WF-4740?

The pump delivers ink to the printhead, maintaining consistent flow and preventing air bubbles that cause missing nozzles or banding.

What connection does the pump use and what does it limit?

It connects directly to the printer's internal ink supply tubes, and its flow rate caps the maximum ink delivery speed during high-density printing.
