Hai all, i need help.
My sharp copier AR-M450 show e7-02.I change the laser motor, still show e7-02 code.
I do the sim61-1,it show..... NG
Should i need to do adjustment or clear error code before i fix the laser motor ?

E7 02 Content Laser trouble
Detail BD signal from LSU is kept OFF, or ON.
Cause The connector of LSU or the harness in LSU
is disconnected or broken.
The polygon motor does not rotate normally.
The laser home position sensor in LSU is
shifted.
The proper voltage is not supplied to the
power line for laser.
Laser emitting diode trouble
PCU PWB trouble
Controller PWB trouble
Check and
remedy
Check for disconnection of the LSU
connector.
Use DIAG (SIM 61-1) to check LSU
operation.
Check that the polygon motor rotates
normally or not.
Check light emission of laser emitting diode.
Replace the LSU unit.
Replace the PCU PWB.
Replace the Controller PWB.
HOPE IT WILL HELP!
If the polygon motor wasn't working you would get an L6-10. The E7-02 means the beam detect sensor never received a beam from the laser. As the previous poster stated you'll need a new laser unit.
Thanks xeroxsharp,ikyl1978,tmaged for your reply.Meaning that i need to change the whole laser unit but not the polygon motor only?
Like Tony says,
L6-10 = mirror motor
L7-02 = laser diode
either way order the laser unit.
If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.
