Compatible High-Yield Cyan Cartridge

The eSquareOne S1-BR-TN336C is a new aftermarket cyan toner cartridge rated for approximately 3500 pages at five percent coverage. It replaces Brother original TN336C and TN331C supplies and fits the HL-L8250CDN, HL-L8350CDW, HL-L8350CDWT, MFC-L8600CDW and MFC-L8850CD printers. The single-pack unit is built to ISO 9001 and ISO 14001 quality standards.

Replaces Standard-Yield Brother TN331C

This cartridge directly substitutes the Brother TN336C high-yield and TN331C standard-yield cyan originals, delivering the higher 3500-page rating in the same form factor. The upgrade is worthwhile when print volumes regularly exceed the lower-yield cartridge's capacity, reducing change-over frequency. It is not suited for users who need a multi-colour pack or a black cartridge in the same order.

Stable Output Across Temperature and Humidity Ranges

The toner is specified to operate reliably between 10 and 32.5 degrees Celsius at 20 to 80 percent relative humidity, with storage tolerance from minus 20 to 40 degrees Celsius at the same humidity band. These environmental limits help maintain consistent page yield and print density during extended print runs rather than only in short bursts. Performance outside the stated ranges is not defined.
