The WX-105 is a genuine Konica Minolta waste toner container designed for select Bizhub series multifunction printers such as the C227 and C287.  Its purpose is to collect excess or residual toner particles generated during printing and imaging, thereby maintaining internal cleanliness of the printer and safeguarding print quality. According to manufacturer listings, it has an estimated capacity of up to ~22,000 pages under standard conditions. Installing a genuine WX-105 as needed prevents toner overflow, alerts the printer’s internal monitoring system correctly, and helps sustain reliable performance.
