📝 Product Description

The Laser Unit – Part No. D03KVH001 (also called laser scanner unit, LSU or laser assembly) is a replacement laser scanner for the Brother HL-L5210DW and related business mono laser printers.

The laser unit sits above the drum. It scans the laser beam across the drum, writing the image of the page. It contains the laser diode, the spinning mirror and its motor. If the laser unit fails, the printer can’t write the image, or the scanner motor error appears.

A faulty laser unit can cause:

• Blank pages, or pages with missing areas
• Vertical white or black streaks, or faint printing
• “Laser unit error” or a scanner or motor error message
• Printer stopping at start-up with a fault code
• Noise from the scanner motor, or the printer not finishing warm-up

Replacing the laser unit restores correct imaging.

Value For Money: pulled from a working printer and tested before dispatch.

Ideal for printer technicians, service centers and dealers.
