Paper Shredder ir paper detector

[spike1947]

Hi
I have a Paper Shredder that ir sensor is not working, changed Caps still no luck, so have given up on that part, the Shredder itself has hardly had much use, the motor works fine ( in reverse ) .
What I am wanting to do is make a small ir proximity paper detector to operate the 24v relay on the main board and disable the original part of the circuit on the main board, there is plenty of room within the Shredder to put another small board in .
Will attach a schematic of the shredder I made just for info as I will not be using that board for the detecting of a sheet of paper.
So really I am trying to find a schematic for such a project ( I don't like stuff going to the the tip ) is there anyone that can give me the info for me to make a schematic for such a thing ! .

Cheers
Spike

Seems to me it would be simpler to track down the fault and fix it.
You'll need to take extreme care with any power up test as it is not mains isolated control.
