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 cyan image drum is suitable for use with C5650 and C5750 printers and will last up to 20,000 prints.
