You can drop off used toners at ABC Office Machines, but if you have a large number of toners, or are not in Grants Pass, another option is your local recycle, or order special boxes from Xerox or Toshiba.
Here are two companies that provide free boxes for recycling empty toner cartridges. Both ship you 3 boxes, and the box has a pre-paid shipping label to return it.
You can put any brand in the Toshiba box, Click here to order Toshiba boxes
Xerox Green World Alliance would like Xerox only toners in the box. Click here to order Xerox Boxes
