Electrical problem on Toko 4750

[LWelch]

Bought a Toko 4750, got running, then it quit. Delivery table switch bad, bypassed it for testing, now when you push ready button, press motor runs no matter what position lever is in, turn button loose, it stops... any ideas? Something's shorted somewhere. Hey, it first quit, tinkering around finally got it to this point. Another ? - where is P1 and P2 boards, P3 & P4 are in the control board box I see those, but not P1 & P2.

Here is an electrical schematic for the 4750. Maybe this will help.

I ask for your help my TOKO 4750 when giving him the 3rd step is locked

It does not advance, manual passes the paper by turning the step but by giving ready lever is locked

It be a sensor in the paper passing that stops the machine?

The Toko has a sensor/switch for each guard and one each for the feeder and delivery tables. The green light will not come on if one of these sensors is bad. If the press shuts off as the paper passes through it is either the double sheet detector setting or the electronic eye that senses paper could be dirty or not seated properly.

Thanks I'll try disconnecting sensor by sensor in order to see which is damaged
