3. Operation
The WT-229CL Waste Toner Box operates passively within your Brother laser printer. Its primary function is to collect excess toner that is scraped off the drum unit during the printing process. This prevents toner from accumulating inside the printer, which could lead to print quality issues or internal damage.
No direct user interaction is required for its operation once installed. The printer's internal sensors monitor the fill level of the waste toner box and will alert you when it is nearing capacity or requires replacement.
