The Canon Imaging Drum sits at the heart of your LBP7010C or LBP7018C printer. It employs an electrostatic charge to pick up toner for text and images and then transfers it to the paper with the help of a fixer. Because wear and tear and toner build-up can lead to deteriorating print output, you can replace your printer's drum with this unit for renewed quality. This drum is rated for 14,000 mono pages and 7,000 colour pages.
