This is a two part questions.
1. Which one will scan faster the HP ScanJet 4200C or HP ScanJet 4300C. Also which one will have the better scanning quality.
2. I got a refurbished ScanJet 4300C because the 4200C I originally purchased had probs and they had no more in stock so they gave me the choice of a new 4200C when more came in or refurbished 4300C. I took the 4300C but there is a bit of dust under the glass. Is there a simple way of removing this, is this just something to expect.
