I don't believe so. Most scanners can perform auto calibration with 
reference to hidden black and white strips inside the case.
For a lot of these scanners that use scanner-on-a-chip designs, that 
process has to be performed by the driver code and I don't think that 
has been written for this scanner as yet.
