this has happened, what 3 times in the last year (this bad).
always white. 2 times of the 3 had a color overtop.
not a big deal to replace, all luckily on small runs.
up until July we were running a small electric dryer. Now big and gas. the cure is waaaaaaay better now. i THINK these were all cured in the old tiny crap dryer. my guess is CURE issue.
ink - for white either wilflex sprint or quick white OR synergy poly white.
top color is wilflex epic line
