Best is to study its repeatability over time yourself. I would take a small
patch count chart and measure delta E's over the course of a day, week and
month. In principle, if should gravitate around a certain set of values but
I don't expect, as I did this to some extent for clients, that it would be
all that stable. We did this on more expensive Xerox's, Canon's and
Minolta's and found the profile we did fresh in the morning was no longer
good in the afternoon, and no amount of recalibrating with the built in
routines would ever get us back the color we'd see in the morning.
