Compatible Drum Unit DR420-13854

The Precision Roller DR420-13854 is a new aftermarket black drum unit built for Brother laser printers and multifunction devices. It replaces the original DR420 assembly in machines such as the HL-2240D, MFC-7360N and intelliFAX-2840. Offices and home users who need a drop-in replacement for routine monochrome printing will find it fits the listed models directly.

Rated Yield 12000 Pages at 5% Coverage

The single figure that determines suitability is the approximate page yield of 12000 pages measured at the industry standard 5% coverage. If your typical documents contain heavier graphics or solid areas of toner, the actual number of printed pages will be lower. Buyers who need a higher yield than 12000 pages should look for a different drum specification.

Consistent Output Over Full Rated Life

The drum is engineered to maintain print density and background cleanliness from the first page through the full 12000-page rating. It does not exhibit the rapid sensitivity drop-off seen in some short-life units, so high-volume batches remain uniform. Environments that demand a longer service interval than 12000 pages will require a drum with a higher rated capacity.
