We have a HP Laserjet 5200 tn that makes a grinding noise and jams in the same place every time. We have replaced the fuser and all of the rollers. I sent a piece of cardstock through it and it gets jammed as well. The jam is inside the top cover just before the toner. the error code is 13.20.00

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

2 possible causes. Transfer roller problem....this is the roller that sits right under the toner cartridge and runs from left to right. Check to makes sure it springs back up when pushed down on both sides. Next is caused by dirty laser optics. This requires dis-assembly of the machine and should be done by a qualified tech. Dirty optics would be more of a concern in a dusty environment or if the printer has been used regularly for at least a year or more.
You are correct in assuming that if the problem was there before cartridge change and after with no change then the cartridge is not at fault.
