How long does the toners and inkjet cartridge last? Is there an expiration date?
Unopened, the inkjet cartridges have a shelf life of at least two and a half years. Once the seal is opened, whether you use it or not, the ink will dry up after six months (This is where the repeat orders come in!). Since the toner is a dry substance and if you keep it in a dry place at room temperature, the expiration date and shelf life will last longer then the laser printer itself! back to top My customers are complaining to me that the inkjet cartridges won’t print! It is important to properly maintain and clean the printing head regularly. If you stop using the printers for a week or more, it is necessary to run the self-cleaning utility for the printer to clean the printing heads.
