Brother TN315BK Black Toner Cartridge

If your print settings are too dark, it could be detrimental to the life of the cartridge in the long run. It’s important that the density control of the machine be properly set to prevent the machine from pulling too much toner into itself.

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.

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.
