After working with the PS 3000 (and suffering with the I-MAX-Board and Scansoftware) for two years we have now the PS 7000 in work. It scans up to 600 dpi b/w for A4 and can now scan books up to A2 (formerly A3). It has - until now- no grayscale option - but this is proposed for summer (?this year?).
We use the scanner first of all for our retrodigitization work: scanning of monographs, journals ... with text-material form the 19./20. Century. The scan itself is fast (about 4 sec for 2xA4 in 600 dpi) but the data transfer takes longer as with the PS 3000 (depending on the growing file size?). The quality of the scan is quite good, the higher resolution has improving impact on the reproduction of details in the image. Our average scan throughput for text oriented books is about 250 pages (=125 shots for "A4 Books").
We scan with a Software, originally developed for the Zeutschel Omniscan 3000, now available for the Omniscan 5000 and Minolta PS 7000 too. The Satz-Rechen-Zentrum company in Berlin (www.srz-berlin.de) developed this software, SRZ ProScan Book in cooperation with our digitization Center (GDZ) to meet special production scanning of older books (e.g. with TIFF-header editing, production control window with tree view over scanned pages, masking and cropping of pages during the scanning process, http://www.agora.de/PrScBk1.htm#Top).
Further information about the con conversion process and some screenshots of the scan-software You can find under the URL:http://www.sub.uni-goettingen.de/gdz/en/gdz_main_en.html#conversio n.
The Scan-software costs about 5000,- DM. You can contact: Hans-Joachim Huebner | mailto:mailto:H-J.Huebner@srz-berlin.de SRZ Berlin | http://www.srz-berlin.de Bessemerstr. 83-91 | Tel:

The ventilator for the PS 7000 is a little bit noisy (more as with the PS 3000 but comparable with a smaller external disk array).
Altogether we have a quite good impression on the new PS 7000 and are now waiting for the integrated grayscale option.
