OKI B840 Toner Cartridges
Looking for a new printer toner cartridge for your OKI B840 that will enhance its performance? All of our mono printer toner cartridges are genuine OKI, ensuring they will help your printer run to its maximum capability.
Same quality, different sizes
The OKI B840 offers everything you need from a mono printer for your business. With the added option to print in A3 as well as A4, the B840 is a versatile machine that will work wonders for any office or home environment.
When used alongside our genuine mono printer toner cartridges, the B840 has a printing capacity of 40 pages per minute for A4 and 22 pages per minute for A3. With a short start up time of 5 seconds, this printer offers speed and versatility in equal part.
To enhance your print run even more, our cartridges have a yield of 20,000 pages. Suited to a range of print and copy tasks, our cartridges offer a range of depth and tone that means that all your documents will be printed to a professional standard.
The greener choice
The OKI B840 is an all-round green machine. Duplex printing options reduce paper costs, while our toner cartridges offer a huge 20,000 pages per cartridge. This will ensure less waste and therefore less environmental impact.
Although some third party cartridges may appear cheaper, they run the risk of damaging your printer. Their reduced yield also means more human intervention to change cartridges and more material waste.
The B840 is made for use with our genuine printer toner cartridges and you can reduce its environmental impact even further with a built-in sleep mode. While the printer is in sleep mode, it reduces energy use to a mere 1.2 watts, which will decrease your carbon footprint and save your business money in equal part.
