Fujifilm DX400W Waste Ink Tank — SKU 16820971

The Fujifilm DX400W waste ink tank (SKU 16820971) is a sealed plastic container that collects excess ink produced during the DX400W printer’s automatic nozzle cleaning cycles, purges, and print head maintenance routines. The printer routes this waste ink into the tank rather than letting it accumulate inside the machine. When the tank reaches capacity, the DX400W’s front LCD panel displays a replacement alert. The tank is a consumable part that must be replaced periodically to keep the printer operating correctly.

The Fujifilm DX400W waste ink tank is accessible from the front of the printer — the same panel used for paper and ink replacement. Open the front access panel, pull out the full waste tank, insert the new genuine Fujifilm waste tank (SKU 16820971), close the panel, and reset the waste tank counter through the printer’s maintenance menu on the front LCD. No tools are required. The tank is a sealed plastic unit — no loose ink spills during removal.

Replace the Fujifilm DX400W waste ink tank when the printer’s front LCD panel displays a waste tank replacement alert. The printer monitors tank capacity automatically and alerts you before it reaches overflow. Do not continue printing after the alert appears — continuing to print risks internal ink overflow, which can damage the printer’s base unit. For production environments, keep at least one spare waste tank on hand so replacement does not interrupt your workflow.

If the Fujifilm DX400W waste ink tank is not replaced when the printer alerts, the tank will overflow. Waste ink will spill into the printer’s internal cavity, potentially damaging the base unit, circuit boards, and surrounding components. This type of damage is not covered under Fujifilm warranty if caused by a neglected waste tank alert. In most cases the printer will stop printing before overflow occurs, but relying on this as a safeguard rather than replacing the tank proactively is not recommended.

No. The Fujifilm Frontier DX400W and the Frontier-S DX100/DX100W use different waste tank specifications. The DX400W waste tank is SKU 16820971. Do not attempt to use a DX100 waste tank in the DX400W — the dimensions, sensor compatibility, and capacity are different. Always use the genuine part number specific to your printer model.

Using a third-party waste ink tank in the Fujifilm DX400W is not recommended. The DX400W’s fill sensor is calibrated to detect the specific characteristics of the genuine Fujifilm tank. Third-party tanks may not trigger the sensor correctly — causing false full alerts that stop production early, or failing to alert before actual overflow occurs. The genuine tank also matches the exact physical dimensions of the waste bay, ensuring a leak-free seal during operation.

Replacement frequency depends on how heavily the DX400W is used and how often automatic cleaning cycles run. High-volume labs running the printer continuously will fill the waste tank faster than lower-volume operations. The printer tracks waste tank capacity automatically and alerts you when replacement is needed — there is no fixed print count interval published by Fujifilm. Monitor the waste tank level through the printer’s maintenance menu and replace when the alert triggers.

The waste ink tank on the Fujifilm DX400W is located in the front access bay of the printer. It is accessed by opening the front panel — the same panel used to replace paper rolls and ink packs. The DX400W is designed for front-access maintenance throughout, so all consumable parts including the waste tank, ink, and paper are accessible from the front without moving or repositioning the printer.
