I ran printing tests on ordinary laser paper and confirmed that the printer
has no skew. I know what I did wrong.
Since I screwed up the center area of the roller (and some of the left
side), I used only the right side of the printer. And since I want to save
on transfer paper I cut it in 4 pieces. Then I used an ordinary paper as a
carrier, folded the top of the piece of transfer paper over backwards,
hooked it on the right side of the carrier and scotch taped the rear of the
fold in place.
I bet the printer traction rollers pulled unevenly on the transfer paper and
moved it slightly off line. I have to somehow secure the piece of transfer
paper properly onto the carrier so that it doesn't move. I can't use tape
on the front 'cause the fuser will melt it and make matters worse.
I just made a test using only 1/2 a sheet of paper and the printer processed
it properly (just a couple blinking lights). So I'll pass 1/2 a transfer
sheet and print only on the right side, not much else I can do. At least
that way I'll get perfectly aligned holes again. I can keep the unused side
for later, hoping that leaving it in the envelope will return it to a flat
shape (it curls up from the heat and jams if I use it again).

Get the service manual for he printer, skew can usually be adjusted out
easily. There are normally two adjustments, one to turn the laser assy (to
get a line parallel with the LE of the paper) and one to make the paper
run straight (to get a line parallel with the side of the paper).
