1. Not used.
0 = Always set to 0.
2. 1 = An L-sync short error has occurred.
0 =An L-sync short error has not occurred.
3. 1= An L-sync long error has occurred.
0 = An L-sync error has occurred.
4. 1 = A laser inferiority error has occurred.
0 = Laser power is normal.
5. 1 = The laser scanner motor is not phase locked and is not rotating at the correct speed.

3. 1= The movement of the photoconductive belt is asynchronous with the accumulator
belt.
0 = The movement of the photoconductive belt is synchronized with the accumulator be
4. Not used.
