High-Yield Toner and Drum Kit

This kit combines a high-yield TN450 toner cartridge with a DR420 drum unit in a single pack. It is manufactured as a compatible replacement for the Brother original supplies. The components are designed to work together in the listed Brother laser printers. Each unit is new and sealed with a two-year shelf life.

Suitable for Mono Laser Printers

The set fits Brother FAX, HL, MFC and IntelliFax models including the 2840, 2845, 2940, 2220, 2230, 2240, 7240, 7360N and 7365DN. It prints black only, so users who need colour output must look elsewhere. Offices requiring original Brother-branded consumables should consider other options.

High-Yield Page Capacity

The TN450 toner is rated for high-yield output, delivering significantly more pages than a standard cartridge. This reduces the frequency of replacements in busy environments. Buyers should verify their printer model matches the compatibility list before ordering.

Questions about this item

When will the DR420 drum unit need replacing after the TN450 toner runs out?

The DR420 drum is rated for a longer life than the high-yield TN450 toner, so you will typically replace the toner cartridge first and keep the drum for several toner cycles.

What is the maximum continuous operating temperature before print quality degrades?

The cartridges are specified for continuous operation up to 30 °C (86 °F); running the printer in ambients above that range can cause toner flow issues and reduced image density.

How much power does the printer draw when these cartridges are printing all day?

Power consumption is determined by the printer model (e.g. HL-2240, MFC-7360N) rather than the TN450/DR420 kit itself; consult the printer’s specification sheet for exact wattage figures.
