When discussing film scanners it is important to not think of "black box wizardry" and break things down into the hardware with its very limited but fixed functions and the software functions which can be upgraded in many cases.
The scanner hardware performs only the basic functions of positioning the film, shining a non variable light source through it, and reading the R, G, B, and black values on a sensor, then transmitting that unprocessed pixel data back to the CPU. The quality of this resolution and dynamic range data is dependent only on the mechanical precision of positioning the film and the quality of the optics and electronic components. These and the surface area scanned are the cost factors. There have been no major technological breakthroughs in the modern era.
Software in the CPU takes that unprocessed stream of X's and O's from the scanner that represent those R, G, B, and black values from the sensor pixels and convert it into a usable file. This software can be from Nikon, Epson, Pakon, Plustek, Imacon. Additionally, 3rd party software such as Vuescan or Silverfast can be substituted totally for scanners using a USB interface from the scanner to the CPU.
This scanner software, typically replaceable, is what makes your output a negative or positive, if it is greyscale or a color file, sets all those various color values, determines if it is a JPEG, TIF or other file type, what size it is, and a multitude of other variables.
Always keep in mind that what comes out of the scanner software is not your finished product, just a file capturing the maximum amount of detail that can later be made into your actual final output in an image processing program such as Lightroom or Photoshop. Assign no significance to how the image coming from the scanner looks. It is not your final output. In fact, most of us find a dull flat looking scanner file produces the best looking final output.
So if you think the output from your scanner could be better, try a replacement for the scanner software to see if that does the trick. Vuescan has a free trial version that works exactly like the paid version.
