First to market for a toner refill solution for Brother TN420 / TN450

123 Refills is first to market with a toner refill solution for the new Brother TN-420 and TN-450 toner cartridges. The Uni-Kit enhanced formula #7 has been qualified to work with these new Brother toner cartridges. The TN420 is the standard capacity and the TN450 is the high capacity version, both of which are compatible with the Uni-Kit enhanced #7 formula which is sold by 123 Refills for $29.99 per refill kit (enough for up to 2 refills).

Refilling these Brother toner cartridges is easy, follow the toner refill instructions which can be downloaded at the Uni-Kit website. Since the TN420 and TN450 are new models, you can follow the instructions for the Brother TN350 for now since they are similar.

Note that the starter cartridges (those that first come with the Brother printers when you first purchase the printer) require a reset gear (which is a small accessory sold separately, but not yet available. When available, it will be listed at the 123refills.net website. The non-starter cartridges do not need this accessory, so can be easily and quickly refilled with the Uni-Kit toner refill kit #7 (enhanced formula).

The printers that accept the Brother TN-420 toner cartridge and Brother TN-450 toner cartridge include the Brother Laser HL-2240 printer series and HL-2270 printer series. The TN420 cartridges have a page yield of 1200 pages, whereas the TN450 have a page yield of 2600 pages. The Uni-Kit Toner Refill Kit #7 comes with enough toner to refill these cartridges at least 2 times, saving you over 75% compared to buying OEM toner cartridges. These Brother printers are becoming popular, with printer prices around $70 on the Brother® HL-2240 Mono Laser Printer (current pricing from Staples), and $100 on the Brother® HL-2270DW Mono Laser Printer (per current Staples offers).
