I have an HP LaserJet 4600dn and envelopes start to seal up from the heat when printing more than 50 envelopes. We print different sizes, #10, #7, #9. Any ideas how to keep the printer from fusing the envelopes closed?

This seems to be a commercial product. For the best chance at finding a solution I would suggest posting in the forum for HP Business Support!
You can find the Commercial Laserjet board here:
Best of Luck!
