Hi, my name is Shereean and I'm the client trainer here at JD Young and today I'm going to show you how to change your toner on a Toshiba eStudio 3505 AC. Your machine will notify you on the screen when your toner is getting low. At that point, you're going to want to order your new toner and once you receive it, you're going to open your front panel like this. Then you will remove your cartridge and dispose of the old cartridge. Then take your new cartridge and slide it in like that. And you're going to close your front panel. It's as simple as that. If you have any more questions regarding your (Toshiba) eStudio 3505 AC or any of our other products, please feel free to give us a call.
