Compatible Black Toner for Brother Printers

The eSquareOne S1-BR-TN420-01 is a new aftermarket cartridge that replaces Brother TN420 and TN450 models. It fits a wide range of Brother DCP, HL, MFC and IntelliFax printers including the DCP-7055, HL-2270DW and MFC-7360N. The single black unit is built for offices and home users who need a direct drop-in replacement.

Operating Conditions and Storage Limits

The cartridge operates reliably between 10 and 32.5°C with a humidity range of 20 to 80% RH. For storage, it tolerates temperatures from -20 to 40°C within the same humidity band. These environmental limits protect toner consistency and prevent clumping during extended downtime or seasonal changes.

High-Yield Output and Printer Integration

Rated at 2600 pages at 5% coverage, the cartridge supports high-volume printing without frequent swaps. It installs directly into compatible Brother laser printers, freeing the user from separate drum units in models that combine both components. Buyers who need colour output or a multi-pack should look elsewhere.

Questions about this item

How do I install the eSquareOne S1-BR-TN420-01 toner cartridge and what step do people often miss?

Open the printer front cover, remove the old cartridge, pull the orange sealing tape from the new cartridge completely, then insert it until it clicks. People often leave part of the tape on, which blocks toner flow.

What maintenance or replacement will the eSquareOne S1-BR-TN420-01 need after the toner runs out?

Replace the cartridge with a new eSquareOne S1-BR-TN420-01 when print quality fades or the printer signals low toner. The drum unit is separate and may need replacement after several cartridge changes.

At what page count does the eSquareOne S1-BR-TN420-01 typically reach its limit under continuous printing?

The cartridge is rated for approximately 2600 pages at 5% coverage. Heavy graphics or dense text will reduce the actual yield before the toner is depleted.
