Digital BW, The Print

It has nothing to do with code information release. The topic you were referring to was adjustment of the individual nozzle output. Epson devised (and patented) a method of testing and control during manufacturing of the heads that allowed them to make corrections for variances between nozzles in the heads. It was done to permit a better pass rate on their factory line output. Otherwise they were having to discard as rejects a substantial part of the production, which left the heads too costly to make.

I don't know the reason they refuse sales of the heads for the Pro model machines but it isn't the "codes". I have suspicions about their reasons though. It's more likely aimed at preserving service work. Paul talked a few posts ago about his FTC days. I once worked for a large well known company who ran afoul of the FTC some years back over just such issues. It ended up in a consent decree that forced them to sell parts directly to anyone with one of their products that needed it. It used to be illegal to force customers to use only "factory authorized" service and to refuse sale of parts to legitimate owners.
