It collects waste ink generated during every printhead cleaning cycle, and the printer will stop printing automatically when the tank reaches capacity. Replacing it with a genuine Fujifilm unit (16820971) is the only way to reset the printer's waste ink counter and return to normal operation.\u003c\/p\u003e\n\u003cdiv class=\"trust-bar\"\u003e\n\u003cspan\u003e✓ 100% Genuine Fujifilm\u003c\/span\u003e \u003cspan\u003e✓ Factory Sealed\u003c\/span\u003e \u003cspan\u003e✓ Authorized Dealer Since 1996\u003c\/span\u003e \u003cspan\u003e✓ Fast Shipping\u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch2\u003eWhy the Maintenance Tank Is Not Optional\u003c\/h2\u003e\n\u003cp\u003eEvery time the Fujifilm Frontier DX400W performs a printhead cleaning — automatically or manually — a small amount of ink is flushed through the heads and collected in the maintenance tank. This is a normal and necessary part of how the printer maintains consistent nozzle performance and print quality.\u003c\/p\u003e\n\u003cp\u003eThe DX400W tracks the cumulative volume of waste ink collected and alerts the operator when the tank approaches capacity. When the tank is full, the printer will halt all print jobs until it is replaced. There is no workaround — the counter resets only when a genuine Fujifilm replacement tank is installed. Using a non-genuine or improvised solution risks overflow, internal contamination, and costly printhead or chassis damage.\u003c\/p\u003e\n\u003cp\u003eFor high-volume labs and photo booth operators running the DX400W through sustained production, keeping a spare maintenance tank on hand is standard practice. Replacement takes under two minutes from the front of the printer with no tools required.\u003c\/p\u003e\n\u003cdiv class=\"warning-box\"\u003e\n\u003cstrong\u003e⚠ Do not attempt to empty or refill the maintenance tank.\u003c\/strong\u003e The tank is a sealed unit designed for single use.

It halts all print jobs automatically to prevent waste ink overflow, which could damage the printhead, contaminate the paper path, and cause expensive internal corrosion. The printer will resume only after a genuine replacement tank is installed.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cstrong\u003eQ: Can I empty the maintenance tank and reuse it?\u003c\/strong\u003e\n\u003cp\u003eNo. The maintenance tank is a sealed single-use unit. It is not designed to be opened, drained, or refilled. Attempting to do so risks ink spills inside the printer and may void your warranty.

When the tank is completely full, the printer halts printing until the tank is replaced. Do not wait for the printer to halt — order a replacement as soon as the low-tank warning appears.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cstrong\u003eQ: How often does the maintenance tank need to be replaced?\u003c\/strong\u003e\n\u003cp\u003eReplacement frequency depends entirely on how many printhead cleaning cycles the printer performs, which in turn depends on print volume, how often the printer is powered on and off, and whether manual cleanings are triggered. High-volume labs running continuous production will replace the tank more frequently than low-volume operations. There is no fixed interval — monitor the printer's alert system.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cstrong\u003eQ: Is 16820971 the correct part number for the DX400W maintenance tank?\u003c\/strong\u003e\n\u003cp\u003eYes. Part number 16820971 is the genuine Fujifilm maintenance tank (waste ink box) for the Frontier DX400W series.
