The Konica Minolta WX-107 Waste Toner Bottle (Part No. AAVAWY1/AAVAWY2) is a genuine OEM waste toner container designed for select Bizhub series colour laser multifunction printers. It collects excess or residual toner particles that are generated during the printing and imaging process—helping to maintain internal print-engine cleanliness, protect critical components, and ensure consistent print quality and reliability. For example, when used in machines like the Bizhub C300i, the unit is rated to handle up to ~44,000 A4 pages at 5% coverage before needing replacement. 
Installation of the WX-107 is straightforward: the service message in the printer prompts when the container is nearly full, and replacing it prevents toner build-up and potential performance issues. Using a genuine container ensures compatibility with the machine’s monitoring system and helps preserve warranty/status indicators.
