Brother MFC-L2750DW 36 ppm Wireless Mono Laser All-in-One with NFC, Duplex Scan, and Fax JAM-INSIDE Error Fix: Paper Jam Inside — Jam Near Drum/Toner Area

Error code JAM-INSIDE on the Brother MFC-L2750DW 36 ppm Wireless Mono Laser All-in-One with NFC, Duplex Scan, and Fax means: Paper Jam Inside — Jam Near Drum/Toner Area. The printer displays "Jam Inside" indicating paper is stuck in the main paper path near the drum and toner assembly area. Open the front cover and remove the drum+toner assembly to access the jammed paper. Gently pull the paper straight out in the direction of paper travel. Do not pull the paper backwards or sideways as this can tear it and leave fragments. Handle the drum assembly carefully — do not expose the green drum surface to direct light for more than a few minutes. After removing the jammed paper, inspect the area for any small torn pieces. Reinstall the drum+toner assembly and close the front cover. If paper jams occur frequently in this location, the paper may be damp (store paper in a dry location), too heavy for the paper path, or the transfer roller may be worn.
