SOURCE: laser unit polygon motor failure

This error usually means that the laser unit on the machine has failed. Just replace the laser unit part number 116-1110-00

SOURCE: the polygon motor can't rotate

Polygon motors are not serviceable items.

If the motor won't turn unless forced then you really need to get it replaced.
The bearings inside the motor can wear out causing excessive noise or seizure.

hope this helps

What is err0r code E 7 02 IN ARM 450 COPIER


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. Meaning that you need to change the whole laser unit but not the polygon 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.
