Choosing between genuine and compatible options
Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Business teams wanting to manage operational budgets can utilise our premium third-party consumables to reduce office costs without risking print text quality. Review the performance benchmarks in our genuine vs compatible cartridges guide to see how they perform.
Managing separate printer consumables
This colour laser printer utilises separate DR-251CL drum units, a BU-220 transfer belt unit, and a WT-220CL waste toner bottle alongside the toner cartridges. Experience Tip: When installing a new drum unit, remember to manually reset the drum counter via the printer menu screen so the printer can accurately track its 15,000-page lifecycle.
Stocking your office consumables
Office teams focused heavily on monochrome text invoices should stock high-yield TN-251BK black toners alongside high-capacity colour options to reduce printer downtime. If you choose third-party options for extra value, our entire range includes a robust money-back guarantee. Free delivery applies on all orders over $99 (conditions apply), with all orders shipped rapidly from our local distribution facilities in Sydney, Melbourne, Brisbane, Adelaide, and Perth. Browse our full selection of Brother toner cartridges to maintain clean workplace documents.
Pro Tip
Always replace your toner cartridges as soon as fading text appears, but do not mistake a worn drum unit for a low toner; a failing drum typically leaves vertical lines or repeating black dots down the entire page.
Frequently Asked Questions
Can I mix a genuine Brother black toner with compatible colour toners in my printer?
Yes, the printer accommodates mixed setups perfectly, meaning you can run a genuine black toner alongside compatible colour cartridges without causing communication errors.
Why does my printer display a replace drum message when I just installed new toners?
The drum unit tracks its wear separately from the toner cartridges; it requires manual counter reset steps upon replacement to clear the warning message on your display screen.
What is the functional difference between a TN-251 and a TN-255 cartridge?
The TN-251 refers to standard capacity black and colour toners, while the TN-255 is a high-yield configuration specifically for the cyan, magenta, and yellow colours to provide more prints.
