Change the toner cartridge , i have many units phaser3200 and this is one of the problem , but only if the toner cartridge is very old and many time refilled , if not , change the Laser unit .

1. Remove a misfed document if the copier displays a message reading "Document Jam." Lift up the document feeder cover and turn the roller to remove an Exit Misfed document. Lower the document feeder back into place and feed the document through again. If the document is jammed on the Input side, open the cover and gently pull the misfed document to the right and out of the feeder.
   
2. Pull out the paper tray and lift the tray to release it from the copier if the copier displays a message reading "Paper Jam O." Remove the jammed document, and open and close the side panel of the copier to clear the error message.
   
3. Unplug the power cord and plug it back in again if the copier displays a message reading "Fuser Error, Open Heat Error, Heating Error and Overheat." If the problem persists, call for a service.
   
4. Remove the toner cartridge and shake it from side to side if the copier displays a message reading "No Developer Cartridge." If this does not do the trick, you may need to replace the cartridge. Pull the release latch to open the side cover, and open the front cover. Twist the cartridge locking-lever upwards and remove the toner cartridge. Insert the new cartridge and lock the lever into place. Shut the front cover and the side cover.
   
5. Power off the unit and power it on again if the copier displays a message reading "LSU Error." A problem has occurred with the Laser Scanning Unit. If the problem persists, call for a service.

There is a fix for this. But only a Panasonic tech has access to the parts for the fix. The toner sensor underneath must be moved closer to the cartridge, you are not low on toner.

E020 indicates a Black Toner malfunction. If you've recently changed the toner and failed to distribute the toner by gently shaking it from side to side, this could be the cause of this error or if the toner is very low it could trigger the same error.
01B0 is a drum error related to your toner error message. If toner cartridge is good, remove the cartridge, clean the drum, replace the cartridge and both errors should clear. A dirty drum will also trigger your 1st error e020.

I had this problems and did everything suggested on here. Installed firmware update (which just changed the error message - didn't get rid of it), removed paper, changed size, replaced paper, tried new cartridge. Nothing worked. Finally found a tiny piece of paper that must have been blocking the sensor. It was on the left side near where the power cable is. It was less than an inch square. Got it out with some tweezers and problem solved.

When you take the toner cartridge off the imaging unit, is there magenta toner in the open slot of the IU? Assuming that there is nothing wrong with the toner cartridge, you are possibly looking at a bad engine control board.

Try changing the photoconductor kit

If you want to use the toner cartridge after the printer decides that it's empty, you can do it by going into the Machine Settings in the menu, and option 8 (at least on my Magicolor 2590MF) says "Toner empty stop?". Just change that to NO, and you're set to go.
