Hi - new poster, but have had my Reader since 12/06. I noticed the same thing with my Reader as well - the ink being lighter than newer versions (I compared with a friend who got hers about a month back).
Unfortunately, after calling Sony Support, they said there's nothing that can be done about it - after going through the requisite hard reset and firmware upgrades questions.
I asked if Sony was aware of the problem and/or able to develop something to improve the ink, but again, nothing out there right now.
So it looks like I will either have to make do with my current one or badger the family for a new one come b-day!
If anyone else has better luck, please do share! Thanks
