1) Your paper tray may be too full, makes it heavy to lift and not enough pressure for the pick up roller.
2) Pick up roller is slippery, wipe it clean with alcohol to make it abbrasive.

if you are getting a paper jam message but you can not find paper any where in the printer the first thing that you want to do is clean the pickup roller in the paper tray. the roller is located on the top of the cavity that the paper tray is installed in.

This is a common issue and most times a bear to repair. There is a
sensor flag mounted on the paper feed assembly behind tray 1 which has
a habit of either coming off or the spring which moves it back a forth
comes out of its holder. In any case it is one of the worst repairs you
have to do. Many items have to come off to get to it and getting that
flag and spring on correctly even with the instructions is difficult.
Usually what will happen is you get the 13.20.00 error on power up with
no motor movement and when you open and close the top cover, the motor
will move but the same error reappears. If you are lucky it is just a
case of a shred of paper blocking the sensor flag from moving and worst
case of the flag having come off. You will need the service manual and
check the removal and replacment section on the paper feed assembly and
play close attention to the 3rd page.
sometimes this error also appears if a wrong fuser is installed in ur printer that is not ur model number.... have it checked
thank you have a nice day
