You are talking about very old system called Zeus1
One of the biggest issues we have had on this systems:
flatcable connections between diff pwbs
I do not remember how often i got claims because of oxidations from these fuck.... flatcable connectors.
On successor models, KDC changed the connectors (in rare cases KDC can learn)
Now i checked each sensor:
Cass1+2 Feed, Regist and Feed1(Mid) are coming from Feed 2 PWB --> Engine YC4 by using fuck... FFC cable without premounted plug
Exit Job always ON because right exit cover is closed...

My biggest problem are Bridge 1+2 sensors.
they are coming from bridge pwb --> engine YC20 without FFC
This i do not understand at the moment (maybe broken 5V circuit on engine pwb/ coming from Feed 2 pwb???)

I would start with dis- and reconnecting from all 3 fuck... FFCs on engine, feed1- and feed 2 pwb.
You must check the FFCs contacts also.

I attach very old list about flatcable problems from Alphard series...(look for possible Zeus errors)

The 5V power distribution at the Feed PWB's is very delicate. In these models, wiring for individual feed units runs behind the left side covers. When replacing feed units, if you do not route the wiring through the saddles, it can become pinched. I watched a tech actually do this while inspecting units.

5v supply for this system comes from the Engine PWB (generated there from a 24v supply) into Feed PWB 1 at YC-3 pin 7 and from PS on YC4 pin 4.

Then check 5V output from Feed PWB 1 at YC12 pin 5 going to Feed PWB 2 YC11 pin 4...if any sensor supply is shorted this goes out and PF sensors have no power.

If voltage is missing, disconnect YC-12 and check for power on YC3 pin 7 again, if it returns short is confirmed.

These boards did fail from time to time.

I have checked the +24v and +5v

YC12 and YC13 YC14 YC16 on the PSPWB

all voltage are good.

I thank all for your support I will try with all these solutions thank you very much

I'm not sure of the difference between the 1 and 2 series. But I had an 8002 do this exact thing. I spent a couple hours on it. It had to do with the little door above the multipurpose tray. The door to remove the duplex jam. It was either not recognizing it was opened or not closed after a jam.

But those flags in the transport get worn down as well and cause all sorts of jamming issues.

None of these rule out losing voltage downstream.

You have a sensor problem, THAT IS WHERE YOU START checking signals. Until you determine the sensors have supply voltage and are changing state there is no reason to go chasing the PSPWB. Sure you could have gotten lucky and found a voltage variance, but as you see now, the problem is not seen there.

if i were a trained kyocera tech., oh i am... i might would try the ole 906 route first. you might get lucky. though i am not gonna tell you that process, as it is for trained techs. not ruling out what everyone else has suggested. i highly recommend trying that as well.

If you are ever to fix your problem, it's important that you understand that you need to check the voltage from point (source) to destination (sensors). Print Whisperer gave you a lot of valuable information as far as the route and boards that are involved. Take a deep breath and take your time.
