Toshiba HR-2505-U Upper Heat Roller 6LJ78116000 for e-STUDIO 2505 2309 2809A

Upper Fuser Roller for e-STUDIO Mono Copiers

The Toshiba HR-2505-U heat roller is the upper fuser roller used in Toshiba e-STUDIO mono multifunction printers. Toshiba lists the part as 6LJ78116000. The assembly carries the fuser lamp inside a coated tube and presses sheets against the lower pressure roller.

A PTFE release layer covers the aluminium tube so melted toner lifts away from the surface. Bearings sit at each end, and a drive gear engages the fuser train. The tube wall spreads lamp heat evenly along the nip, which keeps toner adhesion consistent from edge to edge.

Fitment covers the e-STUDIO 2006, 2007, 2057, 2303, 2303A, 2306, 2307, 2309, 2309A, 2505, 2505H, 2506, 2507, 2802A, 2802AF, 2803AM, 2809 and 2809A. Confirm the model plate against the parts list before ordering. The service manual lists the fuser removal order for each chassis.

Replace the roller when output shows repeat marks at roller circumference, when the release layer scores, or when the fuser logs a warm-up fault. The job needs the fuser unit out of the machine, the lamp withdrawn, and the end bearings transferred. Handle the coated surface with clean gloves, because skin oil creates toner offset.

Key Features

• PTFE-Coated Heat Tube
  The release layer lets fused toner leave the surface without offset onto subsequent sheets.

• Fuser Lamp Bore

  • Hollow tube accepts the fuser heater lamp
  • Aluminium wall spreads heat along the nip
  • Even adhesion across the full sheet width

• End Bearings and Drive Gear
  Bearings seat in the fuser frame, and the gear engages the drive train without shimming.

• Direct Replacement
  The assembly matches the original mounting points, so the fuser rebuild needs no modification.

• Model Coverage

  • e-STUDIO 2006, 2007, 2057, 2303, 2303A
