USB Workshop heeft de Hewlett Packard ScanJet 4200C eens gestest (met USB aansluiting uiteraard). Lees de review hier.
Ok, so it's easy, but it is too easy? There is a tradeoff between simple interface and more control. The user interface is a step by step like, with large buttons, help/zoom-in & out buttons easily accessible, and height, width, scale, size information clearly shown. Changing resolution and rescan option is handy (though somewhat hidden under menus, and didn't know if the source is removed from the scanner when rescan). Cancel takes about 1 second. However, there are several weaknesses. It does not have exposure controls (tone maps, gamma correction, histograms, highlight and shadow, brightness and contrast, emphasis) but only automatic exposure. Intelligent picking of image area can mistakenly pick something wrong or include unnecessary background. To me, the most important of all, it lacks rotation! This way I have to flip the image about 50% of the time in Photoshop or something... or do I really have to remember which way is up? Also, note that images are internally processed and enhanced without user intervention; lack of control probably means processing can't be disabled.
Anyway, on the physical side. It's weighted 6.2 lbs. (2.8 kg), pretty light. The lid flips is extendible for thicker books, it can even be removed. Cables snap on pretty tightly. There is one problem I noticed though. Once after a scan the scan head light (cold cathode?) does not power down for a long time, almost always on. I wonder if that would shorten the life of the tube. Two things are also lacking: there is no stop/cancel button on the scanner, and there is no power switch. But then again, being with USB means that I can unplug it whenever I want and plugging it back in it works, no hassle.
