> Sorry. This is the company whose name is the equivalent to the verb "to copy". If plugging in an obscure codec from some place and checking if one picture looks "OK" is their idea of QA then they deserve all the ridicule and lawsuits stemming from this. You need to put your corporate drone hat on. How many people are involved in making a Xerox copier? How many parts are reused from the previous model? How much software is reused? My best guess is that a large number of components in a copier are engineered in isolation. The image compression people responsible for implementing JBIG2 probably don't even care about correctness beyond some threshold ("not my problem"). The people responsible for ensuring correct copying may not even know that an image compression exists, and even if they do, may not understand the technical nuances of JBIG2, and also may not even have the right documents to find an instance of such a problem.
