With a genuine OKI Cyan Image Drum in your C3300 or C3400 printer, you get renewed print performance for up to 15,000 pages. 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.
