Sounds like fuser issue ( The Fuser Heats the Toner and Fuses the toner to the paper) It could also need a developer change depening on the amout of copies you have on the machine. Unless you can rebuild the fuser or replace the developer, you will have to call a service tech. If your in Maryland you can contact Innovative Copy Products if not go to panasonic.com to find a local dealer

Look where you remove the last jamed piece of paper closest to the fixing unit. Dose it jame when you make one copy? If it dose jam in the same place, I would have to say the problem is in the fixing unit. Look, in the unit for any pieces of paer jamed and remove them. Also, is it only happen with one paper tray and not the other. If so make sure you haze the tray and paper are set correctly.... Really need some more info.

What do you want to install, the toner or you want to power your copier?

Have you been using it?
Or you have just got the copier?

I hope you need to give more explanation on what you need.

bye for now

I hope the there will be an indicator that wil tel you the position of the moisfged paper,
unplug the copier from the power socket, open the indicating unit and remove the paper, do not force the paper anti-clock, pull the paper through the normal running of the paper.

What door or cover is the display showing that it is opened? I would look to see if there is any thing that looks broken on any one of the doors. They have on them little tabs that act as a inter lock device to close a switch. Also, look to see if all the doors close easy without forceing it. try to cheat the doors with a pen or a piece of paper to see which door is not closing. Most of the time a switch or sensor is behind a **** on the inside covers. I would start with retracing the last time you removed a paper jam.

Larry, that depends on which model copier you have.

In order to help you I need the model #
such as FP7735 Dp150 D350 etc.

That's a "Control panel communication abnormal" error. That could be anything from a loose connector under the control panel to bad control panel boards or any of the boards in the back of the machine. If resetting the power doesn't take care of it, it might be toast.
