"TrueBlock" labels are stiffer & stickier than most, perhaps why they peeled off inside my printer and jammed it in a way I can't clear. Avery's "Jam-Free Guarantee": Avery's CS supervisor explained that I had to take the printer to a repair station to document the damage & get a repair estimate ($50-$75 plus my time) before she could "escalate to [her] Management Team for review". She also hinted that I had used the labels in the wrong sort of printer, leading me to expect an unfavorable review outcome, at which time I would have been without a printer for weeks, wasted time, and more money. Not a very useful guarantee! So, I just bought a new printer ($150), which will arrive in a few days. If not too expensive, I'll ship the jammed printer to Avery, just to see how they respond. I'm betting on something like "sorry, but we don't have facilities to examine your printer". We shall see!
