What have you done so far, what is the life of the rollers.....

I only changed pick up rollers in tray 4. After that it shows this problem. I want to make 1 copy but tray 4 picking papers continuously and then paper jammed.

It could be a couple of different things. The first thing I would look at is the paper pickup clutch for tray #4. It could be engaged all the time. If the first paper sensor in tray #4 is not functioning you'll get the same effect. What jam codes are you getting?

Thanks for your help. I changed whole feeding unit from other machine but same. What should we do

I think I would do some diagnosis:

First, I would check the reactions of paper sensors in service mode.
So you just swap things? That's it?

go to state confirmation and find the vertical sensors and make sure they work.
if a konica thinks it didnt feed paper because the 1st or second sensor didnt get tripped it will try to feed again.
remove trays 1 and 2 and watch the action of the feed assy, tell us what happens when it grabs the 1st and subsequent pages. does the take up roller keep grabbing sheets or are they stuck together by static or such.
