Install a genuine OKI Black Image Drum in your C8600 or C8800 printer for the highest quality output and renewed performance. As you use your OKI laser printer, waste toner and wear and tear on parts can lead to reduced quality and poor output. Installing a replacement imaging unit helps to renew your printer's mechanisms, leading to crisp blacks and vibrant colours. OKI printers use a separate image drum and toner cartridge, which helps to keep costs down and save money per page. This item prints up to 20,000 pages.
