Toshiba DEV-UNIT-2809 Developer Unit 6LJ76601000 for e-STUDIO 2006 2809A

Black Developer Assembly for e-STUDIO Mono Copiers

The Toshiba DEV-UNIT-2809 developer is the black developer assembly for Toshiba e-STUDIO mono multifunction printers. Toshiba lists the part as 6LJ76601000 under the code DEV-UNIT-2809. The unit carries the developer mix and the magnetic metering roller in one housing.

The developer station meters toner onto the magnetic roller before the image transfers to the drum. A doctor blade sets the toner film thickness, and the bias voltage holds the mix on the sleeve. The sealed housing contains the developer during transport and disposal. Toshiba does not publish a page yield for this unit; the machine tracks developer life through its service counter.

Fitment covers the e-STUDIO 2006, 2007, 2303, 2306, 2307, 2309, 2323, 2329, 2506, 2507, 2523, 2802, 2803, 2809, 2822, 2823 and 2829. Confirm the model plate against the parts list before ordering. The service manual lists the removal order for each chassis, and the developer unit sits behind the drum and toner cartridge.

Installers remove the toner cartridge and the drum unit first, then release the developer housing from its rails. Guide pins align the new unit on the frame, and one lever locks it in place. No manual bias or gap adjustment is required after fitting, because the machine reads the unit on power-up. Reset the developer counter through service mode after replacement.
