Stocking and delivery options for your office
If your office handles heavy text printing, keeping a spare TN321B black cartridge avoids downtime, as black toner exhausts faster than cyan, magenta or yellow. Multi-packs provide better savings when refreshing all four colours. All compatible toners include a money-back guarantee if they do not perform to expectations. Check our returns policy for total confidence. Free delivery applies on all orders over $99. Orders dispatch quickly from warehouses located in Sydney, Melbourne, Brisbane, Perth and Adelaide.

Frequently Asked Questions
Do TN321 colour cartridges wear out at the same rate during black-and-white printing?
No. When printing monochrome documents, the printer disengages the colour developer units, so TN321 cyan, magenta and yellow cartridges are not depleted during black-only print runs.
Can I mix compatible TN321 cartridges with genuine Konica Minolta toners in the same printer?
Yes. Compatible TN321 cartridges operate seamlessly alongside genuine cartridges, allowing you to replace individual colours as they run empty without replacing the entire set.
What is the shelf life of unopened TN321 toner cartridges?
Unopened TN321 compatible toner cartridges have a shelf life of up to 24 months when stored in a cool, dry place away from direct sunlight and extreme temperatures.
Is TN321B the same as TN321 Black?
Yes. TN321B is the manufacturer product code for the Konica Minolta TN321 Black toner cartridge; the 'B' designation stands for Black.
