Toshiba 6LJ76871000 GEAR-10S20-DRV-FUS Fuser Drive Gear

Fuser drive gear for e-STUDIO mono chassis

The Toshiba 6LJ76871000 is the fuser drive gear used in several Toshiba e-STUDIO monochrome copiers. It transfers torque from the main drive train to the fuser roller assembly. The part carries the designation GEAR-10S20-DRV-FUS-H24X in Toshiba service documentation.

The moulded gear seats on the fuser drive shaft and meshes with the adjacent drive gears. A keyed bore aligns the gear to the shaft flat, which prevents rotational slip under load. Tooth profile and module match the original part, so the drive train keeps its designed backlash and timing.

Compatible chassis include the e-STUDIO 2006, 2306, 2506, 2007, 2307, 2507, 2303, 2303A, 2309, 2505, 2505F, 2505H, 2802A, 2802AM, 2802AF, 2822 and 0906. The part cross-references 6LJ76819000. Confirm the machine model before ordering, because Toshiba uses different fuser drive gears across product families.

Worn fuser drive gears cause uneven fuser roller speed, which appears as repeating marks, blurred fusion or paper transport faults. A cracked or stripped gear can stop the fuser from turning and trigger a jam or fuser error. Replacing the gear restores drive continuity without swapping the complete fuser unit.

Fit the gear with the fuser unit removed from the machine. Clean old grease and toner from the shaft, then seat the new gear fully on the flat. Check that the gear meshes freely with the idler before refitting the fuser. Run a test print and inspect for repeat defects after the repair.

Inspect the mating gears during the same service. Wear on one gear usually spreads to the idler and the drive coupling, and a new gear running against a worn mate wears quickly. Replace any gear with rounded teeth, cracks at the hub or a polished bore. Keep spare gears in the original packaging until fitting.

The gear is a field-serviceable item. Access requires removal of the fuser unit and the rear drive cover on most chassis. Allow the fuser to cool before handling, because the roller reaches operating temperature above 180 °C. Follow the service manual torque values for the drive cover screws.

Order the part by the Toshiba code rather than by description alone. The same GEAR-10S20-DRV-FUS designation appears in parts lists for several models, and stock descriptions vary between suppliers. Verify the code against the machine parts catalogue before dispatch.

The gear ships as a single unit. It needs no lubrication out of the box beyond the small amount of grease specified for the shaft. Excessive grease attracts toner and dust, which accelerates wear on the tooth flanks.
