BROTHER DR3400 COMPATIBLE IMAGING DRUM

The DR‑3400 compatible imaging drum is a high‑performance replacement drum unit built for a range of monochrome laser printers from Brother.

This drum unit supports a page yield of up to ≈ 30,000 pages (at 5% page coverage), making it suitable for high‑volume printing tasks.

When installed with a compatible toner cartridge, the DR‑3400 ensures consistent print density, crisp black‑and‑white output, and reliable performance — ideal for large batches of office documents, reports, invoices, manuals, and busy business use.

Because it’s a drum unit (not a toner cartridge), it handles toner transfer and image formation — giving you stable, uniform results and reducing the need for frequent drum replacement.
