Toshiba D-FC505-Y Developer Unit 6LK49016000 Yellow 150,000 Pages

Yellow Imaging Developer for e-STUDIO Colour Copiers

The Toshiba D-FC505-Y developer is the yellow developer unit for e-STUDIO 2505AC, 3005AC, 3505AC, 4505AC and 5005AC colour copiers. Toshiba lists it under part number 6LK49016000. The assembly meters yellow toner and magnetic carrier to the photoconductive drum at the imaging station.

Two-component development mixes toner with carrier before the blend reaches the drum. That mix holds image density steady through long colour runs. The unit ships sealed, so the carrier charge stays stable during storage. Toshiba rates the assembly for up to 150,000 pages.

Fitment covers e-STUDIO 2505AC, 2515AC, 3005AC, 3015AC, 3505AC, 3515AC, 4505AC, 4515AC, 5005AC and 5015AC machines. The D-FC505 family splits into black, cyan, magenta and yellow assemblies, and each colour carries its own part number. Yellow uses 6LK49016000; the other three colours are separate line items on the same parts list.

Replacement follows the developer-change routine in the service manual. The engineer pulls the old unit, seats the new assembly, runs the setup cycle from the service menu and checks density on a test chart. No firmware update is needed, and the copier returns to service in one visit.
