Appendix A Frequently Asked Question Hardware Q: What is the minimum hardware configuration required for using a scanner? A: (1) Processing Capability Pentium PC with USB port, 32MB RAM, 540MB hard disk is the minimum required configuration. Enough RAM can improve the speed of image processing and large hard disk storage space can be used as data swapping once the memory is not enough. (2) Display Capability A true-color display card which can support at least 16-bit color is required.For the professional user, the higher display card which supports more than 24-bit colors could produces superior color images. Q: What would happen if I do not use the true color card? A: Without a true color display card, the monitor can not reflect the color of original document. You would see many dots on the screen (the dithering image) and color displayed are totally different from the original because of the limited palette (and/or wrong palette set). However, the data captured by the scanner is not affected; that is, the image data stored in the hard disk is independent of display card.
