Toshiba 6LJ54055000 AGIR Mixing Gear for e-STUDIO Developer Unit

Developer Unit Agitator Gear for e-STUDIO Colour Copiers

The Toshiba 6LJ54055000 gear is the AGIR mixing gear that drives the developer agitator inside e-STUDIO colour imaging units. Toshiba lists it under part code GEAR-04H-29-9-MIX-AGIR. It seats on the developer drive shaft and turns the toner-carrier mix during the imaging cycle.

The gear belongs to a four-part set: 6LJ54055000, 6LJ54056000, 6LJ54057000 and 6LJ54058000. Each number covers a different position in the developer drive train, and technicians replace the set together once the teeth show wear. The AGIR suffix identifies this piece as the agitator gear rather than the supply or sleeve gear.

Fitment covers the e-STUDIO 2050C, 2051C, 2550C, 2551C, 2555C, 3055C, 3555C, 4555C and 5055C. These machines share the same colour developer architecture, so one part number serves the whole range. The gear moulds in a hard polymer that holds tooth profile against toner friction.

Why Choose Toshiba

• A worn agitator gear causes uneven toner density, and replacement restores consistent image fill.

• Ordering by part number removes ambiguity when several gears sit on the same shaft set.

• The genuine moulding holds tooth engagement better than generic copies under continuous duty.

• One number covers nine machine models, which simplifies spare stock across a mixed fleet.

• Replacing the gear alone is cheaper than swapping the complete developer unit.
