Who says OCR software can recognize letters? All that it needs to do is execute some algorithm sequentially and blindly against a table of expected values. There need not be any recognition of the character as a character at at all, let alone any "seeing". A program could convert a Word document into an input file for an OCR program without there ever being any optical activity - no camera, no screen caps, no monitor or printer at all. Completely in the dark, the bits of the Word file could be converted into the bits of an emulated optical scan, and presto, invisible optics. Searle wasn't wrong. The whole point of the Chinese Room is to point out that computation is a disconnected, anesthetic function which is accomplished with no need for understanding of larger contexts.
