From copy mode, # * C * to put the machine in service mode, then 14, start, yes, and CA to clear the code. If it returns, remove your fuser and clean your thermistors, if it still returns they may need to be replaced or you may have a problem with your entire fuser.

CE 02 is rarely a machine problem, It normally is an addressing problem between the machine and the network. That code indicates a communication problem, normally relating to scanning.
Often times it is a wrong character in an address.

From FixYa Support: L4 error code means a copier motor fail problem.
Please press # Interrupt C interrupt. Press 16 press start key or print key. If still a problem, please check the motor fuse or see if any kind of gear was broken.

Hope this helps

L4-03 is a lock of the fusing motor. It's likely you need to have the fuser rebuilt. You can try resetting the error by turning off the main power switch (located behind the front door under a little plastic cover) and back on. It's likely the error will come back. There's a cleaning screen on the lower fuser roller which gets gummed up with toner and sticks to the lower fuser roller causing it to seize and the motor not to be able to turn causing the L4-03.
