Imagine a CMYK copier, except remove the CMY toner and developer and insert a new Erasable Blue (EB) toner and developer. Modify the copier so that when the Erasable blue toner passes back through the heat of the fuser, it de-colorizes the blue to white. A new rules based print driver can automatically makes software apps like emails auto print in blue plus provide a new counter to show how much paper, CO2 and money you saved.
The previous generation product appealed to too small a section of the market place but this new 3rd generation product has a much better chance of success as a user still gets high quality black prints. The copier has two toners inside it. K and EB. The new formulation EB toner is a darker shade of blue suitable for permanent storage.
If the pricing can come in at a small premium to a black only copier, there is a good chance of market success.
Plus, this is easily the most innovative new copier product of 2017 with the honor of claiming world's first.
