The WX-103 waste toner bottle is an OEM spare part designed for selected Konica Minolta Bizhub colour laser printers (such as the C-series and “e” models). Its role is to collect excess toner particles that the printer’s imaging system removes during printing. By providing a dedicated container for this waste toner, the unit helps maintain internal cleanliness and printer performance. One specification sheet lists an estimated page yield of up to 40,000 pages under standard conditions. The bottle is designed for straightforward replacement when the printer indicates the waste toner container is full, helping avoid downtime or print-quality issues.
