Pull and check both the Registration assembly and Paper feed assembly. Spin the rollers and gears by hand to make sure they turn freely and are not stuck/locked up. If the problem remains, replace the pickup drive motor.

If the error code remains, then replace to motor as well, or you could replace the jammed part and the motor at the same time.
