No matter how efficient your Brother laser printer is, residual toner is always going to play a part in the running your your machine. Thankfully you can effectively minimise the mess within your Brother printer with the WT223CL waste toner collection box.Elegant in its simplicity, the Brother WT-223CL waste toner collection bottle is a vessel for any loose powder that is left over after your printer has finished fusing. Your Brother colour laser printer automatically collects this powder and funnels it into the WT223CL and when it is full, the toner collection unit can be easily removed and disposed of.
