Toshiba 6LJ76812000 Gear 08S24-08S21 Developer Drive e-STUDIO

Drive Pinion for Mono e-STUDIO Copiers

The Toshiba 6LJ76812000 gear is the drive pinion listed as GEAR-08S24-08S21 in the Toshiba e-STUDIO parts catalog. It transfers rotation from the main drive motor to the developer unit. A stripped or worn pinion produces drive error codes and uneven copy density.

The component uses moulded engineering plastic with a machined bore. Tooth count and module follow the original 08S24-08S21 profile, so it meshes with the existing drive train. The part weighs under 30 g and ships as a single unit.

Compatible engines include the e-STUDIO 2006, 2007, 2303, 2306, 2307, 2309, 2309A, 2323, 2328, 2329, 2505, 2505F, 2505H, 2506, 2507, 2523, 2802, and 2809A. Technicians replace it during developer drive overhaul or when the drive train emits a rhythmic clicking noise.
