Brother DCP-9055CDN Toner Cartridges
Your Brother DCP-9055CDN uses the TN-340, TN-348 toner cartridge series and DR-340CL drum unit. Supplying Australian offices with reliable consumables since Jul 2026, we keep daily document workflows running without interruption. High-volume business printing heavily drains black toner compared to colour, making high-yield TN-348 supplies essential for reducing maintenance stops. Our 4.8 Google rating proves it: we consistently supply premium cartridges backed by rock-solid reliability.
Real-world document capacity and ISO standards
Standard TN-340 cartridges output up to 2,500 black pages and 1,500 colour pages, while high-yield TN-348 cartridges deliver up to 6,000 pages across all colours under ISO/IEC 19798 testing standards. Heavy page coverage will reduce actual yield.

Managing drum units and image maintenance hardware
Color laser printers require periodic replacement of wear components beyond standard toner. The DR-340CL drum unit lasts up to 25,000 pages, while the BU-300CL transfer belt unit and WT-300CL waste toner bottle each run for approximately 50,000 pages.
Experience Tip: When replacing the DR-340CL drum unit, manually reset the internal page counter via the control panel menu while the front door remains open to remove persistent drum error messages.
Reducing printing costs with compatible options
High-yield compatible TN-348 cartridges offer high-volume office environments substantial savings on ongoing supply costs compared to standard consumables. Under Australian Consumer Law, using compatible cartridges does not void your printer warranty. Learn more in our detailed guide on genuine vs compatible cartridges.

Pro Tip
Always replace the WT-300CL waste toner bottle as soon as the printer prompts you, because an overfilled waste box can spill residual powder into the optical path and cause permanent background shadowing across printed pages.
Frequently Asked Questions
Can I mix high-yield TN-348 and standard TN-340 cartridges in the same printer?
Yes, you can install a high-yield TN-348BK black cartridge alongside standard TN-340 colour cartridges; all cartridges in these series share identical physical mounting slots.
Why does my printer display a drum error after I just replaced the toner cartridge?
The TN series toner cartridge holds the powder, whereas the DR-340CL drum unit transfers the image; they are distinct physical components that operate on separate replacement cycles.
Will the printer stop working immediately when the WT-300CL waste toner bottle is full?
Yes, the printer halts all active print jobs once the optical sensor detects a full waste toner bottle to prevent overflow contamination inside the internal paper path.
