Canon FX3 Toner Cartridge 1557A002BA (2.7k)

Most printers have a paper-out detector. On most dot matrix printers it is a photo diode. If form-fed paper is not aligned correctly (usually on the left side) the diode won't see it.

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.

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.
