Canon imageCLASS MF634Cdw toner
Your imageCLASS MF634Cdw takes the 045H (high yield), 045H (high yield), 045H (high yield) and 045H (high yield). At our price that is about 0.9¢ a page.
The Canon imageCLASS MF634Cdw is a mono laser printer in the imageCLASS MF630C series, which shares cartridges across 2 models.
It takes 4 cartridges: the 045H, 045H, 045H and 045H.
On this printer the drum is built into the cartridge, so there is no separate drum to buy or reset. Every new cartridge brings a fresh drum with it.
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.
