The Canon imageCLASS LBP122dw doesn’t require much maintenance, as unlike an inkjet printer, there’s no risk of printhead clogging. That said, if you encounter any print quality issues, you can resolve them by running the built-in ‘Cleaning the Fixing Assembly’ or ‘Cleaning the Drum’ routines in the printer menu. The toner cartridge’s high yield ensures you won’t need to replace it too often. Replacing the cartridge is pretty simple, with the top cover opening wide to give you ample access to the printer’s internals. The drum is also built into the cartridge, so there’s no need to replace it separately. The input tray holds 150 sheets of paper, so depending on how much you print, you may need to refill it regularly.
