Your scanner's imaging device is CIS. CIS imaging will alter hot-pink and hot-orange as well as other shades of pink and red.

Regrettably, there is no correction you can make with software.

You need a scanner that uses a CCD imaging device.

If getting a new scanner, look at the technical specifications. Only use a scanner that is CCD, Charge Coupled Device.

Nearly all, all-in-ones are CIS.
