Detail It is judged that the polygon motor lock signal is not outputted. Lock signal is checked in the interval of 10sec after starting the polygon motor, and it is judged that the polygon motor does not rotate normally.
Cause The LSU connector or harness in the LSU is disconnected or broken. Polygon motor trouble
Check and remedy Use DIAG (SIM61-1) to check the polygon motor operation. Check connector and harness connection. Replace LSU.
You could try to reset the machine with a simulation code 14, which to perform it: 1. Push Clear, Auto, Clear, Auto in a steady rythmic fashion. If done correctly the screen will go blank and all the lights will turn off. If done incorrectly wait 15 seconds then try again. Clear is the red "C" and auto is on the left hand side, the word auto directly above the button.
2. Once you're into this mode enter the number 14 as if you were doing 14 copies then push the green copy key.
If the L6 returns after the reset then you will need service on the machine, Sharp will fix it for a flat rate charge of $140.00 for parts and labor out of warranty. Give them a call 1800 237 4277 in this case.
dear friend:-you can check what is wrong in the movement of optical system .is there any foreign object stuck the movement-is lenses and optical system cover installed in a right way-try to remove the cover and reinstallit.-check lens home position detector connector.
Guest. The L6 indicates the machine is not seeing the motor in the laser, that rotates the mirrors. There are 3 possibilities, I will list them in order of probability. 1 The Laser unit itself. 2. The cable connection on the Main Board. 3. The Main Board itself. The laser depending on the lens, Curved or straight is $323 and $393. the main board will cost in the $250-$400 range depending on the vendor. That is without labor.
