Brother MFC-L2750DW 36 ppm Wireless Mono Laser All-in-One with NFC, Duplex Scan, and Fax DRUM-ERROR Error Fix: Drum Error — Drum Unit Malfunction

Error code DRUM-ERROR on the Brother MFC-L2750DW 36 ppm Wireless Mono Laser All-in-One with NFC, Duplex Scan, and Fax means: Drum Error — Drum Unit Malfunction. The printer displays "Drum Error" or "Drum !" indicating the drum unit is not functioning correctly. The drum unit (DR-730 for mono models, DR-223CL for color) contains a photosensitive drum that transfers toner to paper using an electrostatic charge. A drum error can mean the drum has reached end of life, is scratched or damaged, or is not properly seated. Remove the toner cartridge and drum unit assembly from the printer. Separate the toner cartridge from the drum unit. Inspect the green drum surface for scratches, marks, or toner spills — do not touch the green drum with your fingers as oils degrade the surface. Clean the corona wire inside the drum unit by sliding the green tab from left to right several times. Reinstall and test. If the drum has over 12,000 pages of use, it should be replaced.
