Brother HL-L2350DW 32 ppm Wireless Duplex Mono Laser Printer with WiFi and USB Connectivity MECH-TRANSFER-MARKS Error Fix: Transfer Roller Marks on Paper

Error code MECH-TRANSFER-MARKS on the Brother HL-L2350DW 32 ppm Wireless Duplex Mono Laser Printer with WiFi and USB Connectivity means: Transfer Roller Marks on Paper. Printed pages show marks, smears, or repeating spots caused by the transfer roller. The transfer roller transfers toner from the drum onto the paper using an electrostatic charge. If toner spills onto the transfer roller during a jam or cartridge replacement, it will leave marks on subsequent pages. Open the front cover and remove the drum+toner assembly. Locate the transfer roller — it is the black rubber roller visible inside the printer below where the drum sits. Gently wipe it with a dry, soft lint-free cloth — do not use water or solvents. If marks appear at regular intervals, measure the distance between them: 3.7" apart = drum issue, 1.5" apart = transfer roller, 3" apart = fuser roller. This helps identify which component is causing the marks.
