The same twain driver handle these scanners:
Same family as  KV-SS25, KV-SS50, KV-SS55, KV-SS50EX, KV-SS55EX, KV-SS850, KV-SS855.

Another driver handle the KV-S2055L, KV-S2055W.

However all these scanner show similarities.

	    The TWAIN driver always reads 0x8000 bytes at the time, except for

		thus generating a check condition).

      0x80 image size in dots
         3(?)-4: number of the page to read. Multipage mode.

         returns 16 bytes:
