The Brother TN-3430 HL-L5100DN/DCP-L5500DN 3000 Page Toner is an original Brother toner, formulated for the brand's laser print engines, guaranteeing crisp text and consistent printing from the first to the last document. It has a built-in chip that allows the printer to monitor the toner level and signal in advance when it is running low, independent of the image drum, which is a separate consumable with its own life cycle. It is suitable for replacing the original toner as soon as the printer indicates the need for replenishment, maintaining print quality over time. It has an estimated yield of 3000 pages according to the ISO/IEC 19752 standard and is compatible with Brother HL-L5100DN and DCP-L5500DN laser printers. It is suitable for offices with regular black and white text printing that require an original replacement toner.
