Description
Developer Unit Bushing for e-STUDIO Copiers
The Toshiba developer bushing is a 6 x 12 x 4 mm sleeve that seats the developer roller shaft in compatible e-STUDIO machines. Toshiba codes the part as BUSH-6X12X4-671 and 6LJ54048000. It limits radial play and keeps the roller aligned against the doctor blade.
The bushing uses a low-friction polymer that tolerates continuous rotation inside the developer housing. A flanged profile sets axial position, so the roller cannot walk toward the front or rear frame. The 12 mm outer diameter presses into the housing bore, while the 6 mm inner bore rides on the shaft.
Technicians replace the bushing when the developer roller shows end play or uneven toner laydown. Remove the developer unit, release the roller retainers, and press the old sleeve out. Seat the new part square in the bore and confirm the shaft turns freely before refitting the unit.
Inspect the housing bore for scoring before installation. A worn bore will loosen the new sleeve within a few thousand prints. Clean the bore with a lint-free cloth and avoid grease on the polymer surface. The bushing runs dry and needs no lubrication.
