I have figured out that the alignment mark on the body should be the

Yup, that's right - the sensor is aligned with that mark, and
front-to-back it's a little under halfway back.
When you insert a strip, the leading edge should go in about two-thirds
the depth of the machine before it meets the rear drive rollers. There
needs to be white paper under the sensor when the strip read starts,
hence the need for the inch-and-a-half of white at the head of the strip.
The XRite I have access to is actually at work and used weekly to
calibrate color on a pair of Xerox iGen-3 printers. I'm pretty sure they
are working.
That should be fairly conclusive - but if you want to make sure your own
machine's communcating with it properly, you could try using spotread,
to take single colour readings from whatever's under the sensor without
having to worry about strip recognition.
I'm not even sure if it's reading the strips at all, then again, I
tightly trimmed the paper to the sample region. Looks like I need to
re-print.
Yeah that's probably your problem - you should cut down the dashed
lines, rendering the strips no more than about 4 inches wide (otherwise
you won't be able to read the leftmost strips!) but otherwise you should
leave the paper uncut.
I would have to write it down but I believe it says something
about incomplete read.
That's consistent with "over-enthusiastic" trimming of the paper, so
hopefully that's it. :)
So it would appear.
I have to say I like the DTP41 way more than the eye-one Pro for strip
reading - though it can be very picky about testcharts that are
less-than-perfect.
All the best
