Wave signal is for the laser unit. have you had any L6-10 codes in the history? sounds like you need a new laser. part number is dunt-7039ds11 but thats for a u.k. machine you would have to check for a u.s. m/c.

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.

ERROR SC410 ON AFICIO 4506.. ANY HELP APPRECIATED adanquah@gmail.com


I know an SC 411 means this:

SC411: Separation bias leak error
-Definition- [B]
A separation bias leak signal is detected.
- Possible causes -
• High voltage supply board defective
• Poor connection of the PCU
• Discharge plate defective

Usually a 410 would be in the same ballpark on a Ricoh computer. Unfortunately I don't have the service manuals for 4500 series machines. If you can get a hold of a Ricoh tech in your area, it would be a good idea to rest the power supply and check the pcu as well.
