eSquareOne S1-BR-DR720-8 Compatible Drum Unit Black 8-Pack 30000 Pages

8-Pack Drum Unit Replacement for Brother DR720

This set contains eight black drum units built to replace the Brother DR720. It is intended for offices that run high-volume mono laser printers and want a lower-cost alternative to original equipment. Each unit is new and manufactured under ISO 9001 and ISO 14001 quality systems. The pack suits IT managers who standardise consumables across a fleet of compatible Brother devices.

30000-Page Yield at 5% Coverage

Every drum unit in the pack is rated for approximately 30000 pages when printed at the industry-standard 5% page coverage. That headroom covers months of typical departmental output before a swap is needed. Heavy graphics or dense text will reduce the practical count, so plan replacements sooner for workloads that exceed the coverage baseline. The eight-unit quantity provides a ready reserve for multiple printers or scheduled maintenance cycles.

Operating Range 10 to 32.5°C and 20 to 80% RH

The units are specified to operate between 10 and 32.5°C with relative humidity from 20% to 80%, matching normal office environments. Storage limits extend from -20 to 40°C at the same humidity band, allowing safe stockroom holding. No special mounting hardware is required; each drum slides into the designated Brother slot exactly like the OEM part. The pack includes installation notes for quick, tool-free replacement.
