According to official spec sheets, the typical capacity is rated for approximately 27,000 A4 pages (5% coverage) in certain models. Installing a genuine WB-P08 ensures that your machine’s monitoring system correctly recognizes the container, prevents overflow or leakage, and supports dependable printer operation.
