We have a Xerox Phaser 6140. Recently we have been getting the message to replace the Imaging Unit. I asked our IT manager about it, and he came back and looked at it, removing the imaging unit and then placing the printer back together. Ever since then, I can't print to this printer any longer. When the printer tries to pull the paper through the feeder, it jams. The message "Paper Jam at Tray 1" appears on the screen. I can print through the bypass feeder, but not from the paper tray. We have been comparing the cost of the imaging unit compared to the cost of the printer, so we will probably end up buying a new printer. But in the meantime, I need this printer to keep working! I have been over this printer time & time again, and can find nothing that would appear to be causing this. I hate to give up on it, but I don't know what else to do. Does anyone have any suggestions?
