Brother DR‑3355 Drum Unit – 30,000 Pages

The Brother DR‑3355 Drum Unit (30,000 pages) is a genuine Brother imaging drum designed to work with selected Brother mono laser printers and multifunction devices. As a long‑life consumable, the DR‑3355 is essential for maintaining sharp, consistent black print quality across tens of thousands of pages when used with compatible toner cartridges such as TN‑3320 and TN‑3350.

This original Brother DR‑3355 Drum Unit is compatible with:

• Brother HL‑5440D
• Brother HL‑5450DN / HL‑5450DW
• Brother HL‑5470DW
• Brother HL‑6180DW
• Brother DCP‑8110DN
• Brother DCP‑8155DN
• Brother MFC‑8510DN
• Brother MFC‑8910DW

In these devices, the DR‑3355 drum transfers toner from the cartridge onto the page. Over time, the drum surface wears and can cause:

• Streaks or lines on the page
• Faded or patchy print
• Grey background or spots
• Ghosting (faint repeats of images or text)

Replacing a worn unit with a genuine Brother DR‑3355 helps restore:

• Crisp, dark black text
• Clean, even greyscale graphics
• Consistent image density from page to page
