Compatible Drum Unit 10-Pack

This eSquareOne S1-BR-DR820-10 set contains ten black drum units built to replace the Brother DR820. It fits a wide range of Brother DCP, HL and MFC laser printers used in busy offices. Each unit is new and manufactured under ISO 9001 and ISO 14001 quality systems.

Operating Environment and Reliability

The drums are rated for use between 10 and 32.5 °C at 20 to 80 % relative humidity. Storage limits extend from -20 to 40 °C under the same humidity range. These conditions support consistent print quality and a 30 000-page yield at 5 % coverage per unit.

Installation and Daily Use

The pack supplies ten replacements so high-volume departments can keep spares on hand. Units slot into the printer without extra tools and include installation notes. The 100 % satisfaction guarantee and two-year replacement coverage reduce downtime risk for maintenance teams.

Questions about this item

How do I install the eSquareOne S1-BR-DR820-10 drum unit in my Brother HL-L6200DW, and what step is often missed?

Open the front cover, remove the toner and drum assembly, press the green lock lever to release the old drum, insert the new eSquareOne unit until it clicks, reinstall the toner, then reset the drum counter via the printer menu — skipping the reset causes the replace drum warning to stay on.

What maintenance or replacement will the eSquareOne DR820 drum units need after the 30000 page yield is reached?

Each drum unit is rated for 30000 pages at 5% coverage; once that yield is reached the drum must be replaced, and the printer will prompt you to install a new unit from the 10 pack.

What limit appears first during sustained high-volume printing with the eSquareOne DR820 drum?

The operating temperature ceiling of 32.5°C is the first limit reached; running the printer above this temperature can degrade print quality and shorten drum life.
