I down/sideloaded a PDF which looks fine on my Kindle Keyboard but displays as a rather poor scanned image on my Kindle Fire 2
That's John Clark's _Ignition_ and two others from
http://library.sciencemadness.org/library
Any suggestions ?

As to (b) I edit to report that two PDF Apps (both free) render the pages fine, unlike the Amazon Fire's default.
Adobe Reader
Foxit Mobile PDF
click the various options and the scan can also be seen.
