Brand new C450i with 3205 jam code

[jwrycza]

I just installed this machine a week ago and it is constantly jamming on 2 sided prints. Always J-3205. It looks as though the paper is crashing into the gate as it is trying to exit the machine. I ran 125 double sided prints with no problem, then the client runs a few random ones here and there and I had to go back as it jammed. There is a nip, it appears, on the leading edge but every thing i can feel is smooth. I ran through the manual and the sensors work, all motors load checked good so, it says to replace the EXCB. Wanted to see if anyone has more ideas before I order the board.

Re: Brand new C450i with 3205 jam code

Is it only jamming on double sided or single sided as well?
Have you removed and inspected the switch back section?

If you open the side door and close the duplex/syncro section you can make the door switch and watch the gate operate to see in its moving all the way. The switch back selector gate must be in the middle of the travel distance for single sided if its to much to one side it can cause timing issues. It could also be that there is some issue with the sensor or actuator. If those clear plastic "guide" bits on the exit unit on the door side is not installed correctly the gate can catch against them.

Re: Brand new C450i with 3205 jam code

We have had several 450i,s that were almost brand new that we tried several things we ended up replacing exit/turn over section to fix it on all of them. KM has really went down hill when it comes to quality control

I would replace fusing loop sensor PS2.

A nip? Maybe something like this.

It is a bit more exaggerated than that but, it doesn't match up with the ribs on the exit.

It is only on double sided printouts. I did remove the exit unit and "adjusted" the solenoid per KM bulletin but, I did not work. I will check the switch back when I get there later today.

Before replacing a board I would try adjusting the fuser transport speed a little and see if that helps.

Re: Brand new C450i with 3205 jam code

I have opened a ticket with KM I had this issue in the turnover unit that folds corners/skews/ and jams in the revs unit. I have had over 5 MFP, Provided them all the SSN and said they will pass it along yet have not seen anything about a fix or nothing relating to the revs unit. The fix I have found is to remove the one sep claw closest to the back of the MFP on the REV unit have had no issues with any of the MFP's after doing this. We still have Brand new setups that do the dog earing when setting them up and removing this fixes all that.

Re: Brand new C450i with 3205 jam code

Hello. I literally just wrote about this. It's a standard issue with KM dating back to the Bizhub c224e models.
The problem is with the guide shutter. When the paper is fed for duplex printing, the actuating solenoid does not lower the shutter in time for the paper to start moving towards the upper compartment.

May or may not help but i just fixed a 3003 jam code on a c300i where it would stop every time as it was passing thru the fuser. The issue was with the baseboard. Once replaced it was fine. I had tried a EXCB board prior to the main board with no luck,

We still have Brand new setups that do the dog earing when setting them up and removing this fixes all that.

We have found that a number of our machines were plagued with a dog-ear problem, on the rear side of the machine, which would subsequently lead to jams, especially on duplex. We found that on the machines that were doing this, the side guides (front and rear) in each of the paper trays (1 and 2) were not centered, but positioned all the way to the back on the scale in the paper trays, right from the factory (See attached image). We initially thought that the customer was shutting the drawers too hard, but after looking at a number of machines we still had in our warehouse inventory, we found that most of them were the same way. After adjusting the front to back centering in each of the trays back to the center of the scale, this corrected the dog-earing and the jamming that was being caused by those dog-ears.

Once this is adjusted, you will need to go into service mode and adjust the print centering, but that's a small price to pay for fixing the dog-ear and jamming problem.

Open the right door and remove pre roller on the exit unit above the fuser it has 2 self tapping black screw..and your problem is sorted forever

To be accurate it was 32-06 jam.
