Error code l 4 01
L4-01 is a main motor lock error. More than likely something is locked up, rather than a problem with the motoer itself. Make sure the drum and Developing unit are turning freely. The Fusing unit binding can also cause this error. Turn the machine off, remove the developing unit and the drum. Put the developing unit back into the machine, close the doors and turn it on. If you can hear the motor run and there is no error code, then the drum is locked up, probably due to a flipped cleaning blade. The next area to check is the developing unit itself. Sometimes if the bushings go bad at the ends of the developer roller, it will cause a motor lock. There is a white coupling on the rear side of the developer unit. Turn it counter clockwise about a half turn, being careful to hold the unit level. There should be little resistance. If all seems O.K., then the Fusing unit is probably the cause. Also pull out the paper cassette and make sure nothing is preventing the pick up rollers from turning.
