i tested the fuses on the print board to see if any had shorted
i also ran all the adjustments but as soon as i do the toner initialization the machine goes into the 2451-2454 codes before it completes it process

because your getting tcr level codes and erase lamp codes at the same time I would check the plug on the back of the process unit that connects to the main body to see if it is damaged.
