High-Yield Black Toner 4 Pack

This pack contains four new high-yield black toner cartridges manufactured by Ninestar Technology as an aftermarket alternative to Brother TN450 and TN420 supplies. The cartridges are built to meet or exceed the original equipment specifications for consistent page output.

Compatible Brother Mono Laser Printers

The cartridges work with the Brother MFC-7360, MFC-7460, MFC-7860, HL-2220, HL-2240, FAX-2840, FAX-2845, FAX-2940, IntelliFax 2840 and IntelliFax 2940. Printers outside this list or colour laser models are not supported by this toner formulation.

High-Yield Page Capacity

Each cartridge is rated for high-yield printing, delivering substantially more pages than the standard TN420 version. Buyers who only need the lower page count of the standard cartridge should select that model instead.

Questions about this item

Should I choose the 4 pack or a 10 pack for my Brother FAX-2840?

This listing supplies a 4 pack of high-yield black cartridges. A 10 pack version exists under the same model but is a separate offer; pick the 4 pack if you want fewer cartridges upfront.

What does high yield mean for daily printing on my HL-2240?

High-yield TN450 cartridges contain more toner than the standard TN420, so each unit prints more pages before replacement, reducing change frequency on the HL-2240.

Does the TN450 chip work with the Brother MFC-7860 without firmware issues?

These cartridges are built to meet or exceed OEM requirements for the MFC-7860 and listed models, and using them does not void the printer warranty.
