Toshiba D-FC338K Black Developer Unit 125,000 Pages for e-STUDIO 338CS

Black developer assembly for e-STUDIO 338CS

The Toshiba D-FC338K developer is the black imaging developer for the e-STUDIO 338CS multifunction printer. Toshiba rates the assembly at approximately 125,000 pages. The unit ships sealed and seats directly in the developer bay. It is an original Toshiba supply, not a rebuilt assembly.

The developer carries a black ferrite carrier mix and holds the toner charge across the imaging cycle. An integrated housing seals the carrier from dust during storage. The assembly mates with the drum unit and the toner supply without any calibration step beyond the standard install routine.

One part number covers the e-STUDIO 338CS, and the same housing also appears in the 388CP and 388CS listings. Keep the carton upright and away from magnetic sources until fitting. Confirm the machine badge against the compatibility list before breaking the seal. The unit ships with a protective cover over the developer sleeve.

Key Features

• Rated 125,000 Pages
  Toshiba publishes approximately 125,000 pages per assembly, which covers a long service interval for a single workgroup device.

• Sealed Carrier Housing
  The closed housing keeps the ferrite carrier clean and dry until the technician opens the seal at installation.

• Direct Bay Fit
  The assembly slides into the developer slot and locks without shims or field calibration.

• Installation Notes

  • Remove the protective sleeve cover before seating
  • Run the standard developer setup routine from the service menu
  • Dispose of the old assembly through the usual consumable channel

• Stable Charge Control
  The carrier mix holds toner charge across the rated life, so image density stays flat between service visits.

• Original Toshiba Build
  Toshiba manufactures the housing and carrier to the same tolerance as the unit fitted at the factory.
