Toshiba OD-2505 Black Drum Unit 6LJ83358000 for e-STUDIO 55k Pages

Photoconductor Drum for Toshiba Mono Copiers

The Toshiba OD-2505 drum is the black photoconductor cylinder for a broad range of Toshiba e-STUDIO mono multifunction machines. Toshiba codes the part as 6LJ83358000 and OD-2505. The unit carries a rated yield of approximately 55,000 pages at 5 percent coverage on A4.

The drum uses an organic photoconductor coating on an aluminium cylinder. The layer holds a uniform charge across the page width, which keeps black text and line art sharp. A protective shutter covers the surface during handling and transport. The cylinder seats on the existing drum shaft inside the imaging housing.

Technicians fit the drum after removing the imaging unit from the machine. Release the drum lock, slide the old cylinder out, and seat the new one on the shaft. Confirm the drum turns freely before closing the housing. The machine resets the drum counter through the service menu after installation.

Store the drum in its sealed bag until fitment. Exposure to light degrades the photoconductor coating over time. Handle the cylinder by its ends and avoid touching the coated surface. Clean the drum with a dry lint-free cloth only if visible dust settles during service. Check the drum shaft and the imaging housing for toner buildup before fitting the new part.

Compatible models include the e-STUDIO 2006, 2007, 2306, 2307, 2505, 2505F, 2505H, 2506, 2507, 2303A, 2303AM, 2309A, 2323AM, 2523A, 2523AD, 2802AF, 2802AM, 2803A and 2809A. Confirm the machine plate before ordering, because Toshiba uses different drum assemblies across model years. A mismatch will cause poor image quality and premature wear on the drum surface.
