Hi Roger,
On a similar note there are 2 interesting links on Edmund Roland's blog which
might help answer your question.
http://photofeedback.blogspot.com/2005/11/dtp70-bill-atkinson-targets.html
If you take a look at the link to the tests's that Bill Atkinson is doing you will
find comparisons between the speed of the iO & the DTP70. I found the
extended charts designed for the DTP70 with its modified feeder tray most
illuminating. There are downloadable charts for the Spectrolino, the iO &
the DTP70 plus repeatability tests & sample measurements for the Epson 9800.
regards
Richard
