Hopefully you can help with our envelope printing problem on our HP LaserJet 4100 DTN.
We have the optional 75-envelope feeder tray that shares the same spot with the manual feed tray (tray 1). Although it displays in the printed Configuration Page (under heading Paper Trays & Options, listed as "Envelope Feeder (COM10) ), it will no longer print to the envelope feeder but only wants to recognize the manual feed tray when you're actually printing.
We had no problems for 10+ years until recently when it sporatically wouldn't work for some users. When reported to me it would then work, but now no longer works at all. It is networked and has been shared out on the same server for a couple of years now.
Any suggestions would be most appreciated!
Thanks!
