Have installed new fuser unit. Now it seems the same with a few less wrinkles in jammed paper.
The machine still puts out a great two sided test sheet in color on one side upon start up completion. I don't understand why it won't work in normal copy operation after that. paper comes from the same paper tray, the #3.
I have taken pic of companion to fuser unit which swings out when door is open to remove jam. This unit works with fuser in feeding paper into feeder I am guessing. It looks like this roller is a little discolored and has shiny surface on parts, but still seems to have rubber gripping power.
Please advise and thank you so much for your input. Very important re-inforcement of my thought process.
