The Brother drum unit is a separate consumable that typically should be replaced after the use of 3 or 4 toner cartridges. If you own any of the Brother laser printers listed below and you are getting a "Replace Drum" message on your machine's display, it might be time to get a new drum. Your printer uses a page counter to track usage, which must manually be reset every time a new drum unit is installed. Instructions for both steps are included below!
Compatible Brother laser printers:
Brother HL‑L5000D / HL‑L5100DN / HL‑L5200DW / HL‑L5200DWT / HL‑L6200DW / HL‑L6200DWT
