Patch Sensor � Help

[Maher]

I do not work with a lot of Canon products . I have a very good experiencein Copier Troubleshooting with other brands .
I am trying to do my homework to gain more knowledge about Canon Copiers .
I am struggling to find good information / Documentation regarding how tocheck the functionality of Patch sensor in service mode
For example , what is the difference between these 3 itemes
L2 --> Copier --> Display --> DENS -->P-LED-DA
L2 --> Copier --> Display --> DENS --> P-SENS-P
L2 --> Copier --> Display --> DENS --> P-SENS-S
If anyone has a clear explanation or good Documentation to explain thatwould be very very appreciated
Thank you again
