Toshiba Heater Drive Gear 10S38 6LJ76809000 for e-STUDIO Copiers

Heater Drive Coupling Gear for e-STUDIO Mono MFPs

The Toshiba heater drive gear carries part number 6LJ76809000 and the Toshiba gear code GEAR-10S38. It sits in the heater drive train of the e-STUDIO 2006 platform, where it couples the drive motor to the fuser assembly. Technicians replace it when the drive train slips, rattles or strips teeth.

The gear is a single-piece moulded component listed as a heater drive coupling in the Toshiba parts catalogue. It meshes with the adjacent idler and fuser drive gears on the same shaft line. Torque transfer runs from the main drive motor through the gear train to the fuser rollers.

Compatible chassis include the e-STUDIO 2006, 2007, 2303A, 2303AM, 2306, 2307, 2309A, 2323AM, 2329A, 2506, 2507, 2523A, 2523AD, 2809A and 2829A. The same gear serves the 2507 and 2809A variants that share the fuser drive housing.

Key Features

• Original Toshiba Part Number
  Part 6LJ76809000 matches the factory heater drive coupling drawing for the listed chassis.

• GEAR-10S38 Designation
  The moulded gear carries the Toshiba 10S38 gear code stamped into the parts catalogue entry.

• Single-Piece Construction
  The coupling moulds as one unit, so it seats on the shaft without separate hub or collar parts.

• Service Application

  • Restores torque transfer to the fuser drive rollers.
  • Removes rattle and slip from a stripped drive gear.
  • Fits the 2006, 2007 and 2507 family fuser drive housing.
  • Supports the 2303A, 2309A and 2809A mono platforms.

• Drop-In Replacement
  The gear installs on the existing shaft without machining or adapter hardware.

Installation and Inspection

Switch the copier off and disconnect the mains lead before opening the rear or side cover. Remove the drive housing screws and lift the housing clear enough to expose the gear train. Note the orientation of the old coupling before pulling it from the shaft.

Clean any plastic debris from the shaft keyway and from the teeth of the mating gears. A stripped coupling usually leaves shavings inside the housing, and those shavings accelerate wear on the replacement. Wipe the shaft, then press the new gear on squarely until it bottoms against its shoulder.

Rotate the drive by hand after fitting and confirm the train turns without binding. Check that the gear sits flush and does not foul the housing wall. Run a few test copies and listen for rattle at the fuser drive before returning the machine to service.

Inspect the drive train at each scheduled maintenance visit. Heat and load harden the moulded teeth over time, and a gear that shows a flat or glossy tooth face will fail shortly afterward.
