Toshiba 6LK49455000 Power Supply Assembly ASYB-PS-HVT-H370 for e-STUDIO 2000AC 2520AC

High-Voltage Power Supply Board for e-STUDIO Colour Copiers

The Toshiba 6LK49455000 power supply is the high-voltage power supply assembly for Toshiba e-STUDIO colour multifunction printers. Toshiba codes the part ASYB-PS-HVT-H370. The board generates the high-voltage rails that charge the drum and bias the developer station.

The assembly converts AC input into the DC and high-voltage outputs used by the imaging process. Separate rails feed the main charger, the transfer charger and the developer bias. A shielded enclosure limits electrical noise, and the board seats on guide rails inside the rear frame.

Fitment covers the e-STUDIO 2000AC, 2010AC, 2020AC, 2500AC, 2510AC and 2520AC. Confirm the model plate against the parts list before ordering. Technicians replace the unit when the machine logs a high-voltage fault, when output density collapses or when arcing appears at the charger.

Key Features

• High-Voltage Output Rails
  The board supplies the charger, transfer and developer bias voltages required by the imaging process.

• Model Coverage

  • e-STUDIO 2000AC, 2010AC, 2020AC
  • e-STUDIO 2500AC, 2510AC, 2520AC
  • Confirm the model plate against the parts list

• Shielded Enclosure
  The metal cover limits electrical noise that would disturb charge uniformity across the drum.

• Guide-Rail Mounting
  The assembly slides onto frame rails and locks in place without a calibration step.

• Fault Symptoms Addressed

  • High-voltage fault codes logged by the machine
  • Density collapse across the full page
  • Arcing or clicking at the charger assembly

• Service Part Numbering
  The OEM number 6LK49455000 matches the service manual and simplifies parts ordering.

Specifications

What’s in the Box

• One high-voltage power supply assembly, 6LK49455000

• Protective packaging

Why Choose the 6LK49455000

• A failed high-voltage rail shows up as density collapse or charger arcing, and this board restores both rails in one visit.

• One part number covers six e-STUDIO colour models and reduces spares line items.

• Guide-rail seating removes calibration steps from the service call.

• The shielded cover keeps electrical noise away from charge and developer control.

• Genuine Toshiba supply keeps output voltages within the imaging process design tolerance.
