Digital BW, The Print

Under pressure, printing for a show I ran out of Innova Fiba Gloss
11x17. I emailed Jim Doyle and got a new pack. I also requested a pack
of 13 x 19 for some larger panos. Turned out that was back ordered,
but Jim had just gotten in 13 x 19 warm tone Fiba Gloss. I was
printing toned images using a 2200 with ultrachrome inks and quadtone
rip and neutral images using mis fsn inks on a 1280. They both worked
perfectly or reasonably so with the old Blue Label (lumpy grain) stock
and with the new Black Label in 11 x 17. Then I tried printing the
warm tone. A total disaster. Clog after clog on both the ultrachrome
inks and the mis. Spent more time cleaning heads than printing and
every print but one developed a problem in the midst of printing.
Finally did the large pano on Innova Photo Smooth - no problem - using
the mis inks. Probably could have done it also on Ultrachrome and
gotten the tone I wanted, but I was running out of time. 

Is it possible for a paper to clog heads? Has anyone else had this
experience. I've asked Jim the same question, but have not received an
answer. I'm assuming he's out of town since he is usually quick to
respond.
