Brother HL-L9430CDN toner
Your HL-L9430CDN takes the TN815BK (high yield), TN815C (high yield), TN815M (high yield), TN815Y (high yield), TN810BK (standard yield), TN810C (standard yield), TN810M (standard yield), TN810XLBK (high yield), TN810XLC (high yield), TN810XLM (high yield), TN810XLY (high yield) and TN810Y (standard yield). At our price that is about 0.3¢ a page.
The Brother HL-L9430CDN is a mono laser printer in the HL-L9400 series, which shares cartridges across 3 models.
It takes two black cartridges that differ only in capacity: the TN810BK at about 9,000 pages and the TN815BK at about 15,000. At our prices that is 0.4¢ a page against 0.3¢, so the high-yield cartridge costs less to run unless you print very little.
Brother has stated publicly that its firmware updates do not block third-party cartridges, and the printer counts pages rather than measuring toner, which is why the Replace Toner message can appear before a cartridge is empty.
When you compare prices, compare cost per page rather than the sticker price: a cheaper cartridge with half the rated yield costs more to run. Every cartridge here ships free, is covered by our printer damage protection and can be returned within 90 days, opened or not.
