Brother HL-L3270CDW 25 ppm Wireless Duplex Color Laser Printer with WiFi, Ethernet, and Touchscreen MECH-TONER-FALSE Error Fix: False "Replace Toner" Alert

Error code MECH-TONER-FALSE on the Brother HL-L3270CDW 25 ppm Wireless Duplex Color Laser Printer with WiFi, Ethernet, and Touchscreen means: False "Replace Toner" Alert. The printer displays "Replace Toner" when the cartridge is not actually empty, or a new cartridge triggers the replace message immediately after installation. Brother printers use a page counter and gear mechanism on the toner cartridge to estimate remaining toner — this can be inaccurate. For a new cartridge triggering the error: ensure the orange sealing tab was fully removed (pull it straight out until the entire strip is free), the cartridge clicked fully into the drum unit, and the drive gear on the cartridge is intact. Some printers allow you to continue printing past the "Replace Toner" message by pressing a button sequence or changing a setting: go to Settings > All Settings > General Setup > Replace Toner and set it to "Continue." The printer will print until quality actually degrades, then display "Toner Ended."
