Brother MFC-L2980DW Monochrome Laser All-in-One Printer

Use a lightly dampened cloth to clean the outside of your laser printer. To clean the inside, use a dry, lint-free cloth to make sure that no liquid enters the inner parts of the printer.

Getting blank pages after you installed a new cartridge? Check that the sticker from the cartridge was properly removed. Alternatively, run the clean print head function to make sure all air bubbles are removed. Do not remove the cartridge once it has been installed.

If debris is the primary cause of failures, toner is the primary cause of debris. All toner cartridges release a small amount of toner powder into the machine. This is why it's important to clean the machine when you change the cartridge.
