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.

Most printers have a built-in diagnostics program which can be very useful for troubleshooting problems and test-printing without a computer. They are usually initiated by pressing a button or two while turning on the printer.

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.
