Oki B4500 toner and drum
Your B4500 takes the 43502301 (standard yield), plus the 43501901 drum. At our price that is about 0.5¢ a page.
The Oki B4500 is a mono laser printer in the B4500 series, which shares cartridges across 4 models.
The cartridge it takes is the 43502301, rated by Oki at about 3,000 pages, which works out to roughly 0.5¢ a page at our price of $15.99.
The drum is a separate part on this printer. The 43501901 is rated for about 25,000 pages, so it outlasts several toner cartridges and only needs replacing when the printer reports drum life, not every time you change toner.
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.
