I don't really believe that Aer Lingus passport scanners can be faulted for the fact that some of the type face is missing from my passport. I believe my passport was a shoddy product sold to me by the US Dept. of State. The scanner may have rubbed the ink off, but that was because the ink or the paper was no good to start with.
If there was a general fault with the scanners I'm sure this would have been an issue by now.
