Misfed document error on screen

i've seen this one a lot when i worked as a repair man for toshiba, unfortunatley even the smallest piece of paper or a clump of dust in front of a sensor will cause a "missfeed error", if you havent already; try removing some of the basic parts on the inside and spray everything with a compressed air can like you'd use to clean the key boards, then reset the copier and hopefully that will take care of you're problem.

Sometimes small piece of paper, tissue and etc also can triggered the sensors...
Skill needed to open up everything in order to inspect.
Did u manage to get error code?

there may be a piece of paper or a sensor is stuck,
1st remove trays and open all doors
2nd locate each sensor and see if it stuck or has something blocking it

The part that is up is the flag for the sensor , it tells the machine if there is a paper there, if it is late getting there, etc...

3 rd start with the trays, next to the wheels there should be two, one to tell it if the tray is full of paper and one to tell it it is coming out, you should be able to pull lightly on it and it should snap back into place (there is a spring inside that puts it back in place after the paper has passed)
4th look on the side where the paper should be going up
5th if you have a duplexer (2 sided option) look in there
ALL GREEN HANDLES ARE FOR USERS TO MOVE TO LOCATE PAPERS IN COPIERS
6th look in the exit where the paper comes out
some copiers ( possibly this one) you may have to physiccally remove it to see. ( wait until it cools off)

Good luck
