Hi fellow copier dealers. Have an interesting problem that occurs when duplexing on this machine. The paper ends up at the top of the inverting unit before the ADU entrance sensor the majority of the time however code J82 is the predominent error thrown. We have replaced one of the paper exit transport solenoids and are going to try removing one of the arms. Any other ideas? We have done quite a bit to the machine in regards to this problem so it might be easier for you to throw out ideas/solutions you've used and we'll let you know if we've tried them.

Oh, where do I begin. The 8035 fusers are crap, so check the web is not frozen or for flat spots on the press roll. Check the action of the inverter gate; make sure it doesnt catch on the green tab on the yellow and black fuser exit gate. Check the actuator inside the inverter, it gets worn on its face and can slow paper down. There are two service bulletins for that section. One has to do with the clips which hold the door latch, the other has to do with a clutch in the main drive motor. If you find 2 sheets in the paper path on top of each other, it is the main motor clutch. This is gonna sound wierd but i've seen it work numerous times. Take the ADU entrance sensor and swap it with either of the other 2 ADU sensors. I don't know why, but it works often for J82 codes. Also make sure the solenoid for the inverter is firing and both springs are present.Failing to plan is planning to fail!!! -
Thanks for the information. I passed it along to the tech. I know he removed the solenoid arm and was waiting to see how that worked. Will let you know.Comment

I just heard from a tech who was having J-17 errors, he told me it turned out to be the registration sensor loaded with paper dust, I haven't seen it occur myself, but he said if he went into F4 input mode 3 sheets would activate the sensor, but 1 sheet would not, he ended up replacing the sensor and said it was good to go.Comment

Mojorolla,
The solenoid arm removal did not work nor did anything from your first post. Any other ideas we can check out? Also, there is a page in the service guide for these machines that relates to paper wrinkles on the 8035 and talks about replacing the lower pressure roller and bearings with ones from the 8045/8060. This roller is quite a bit bigger though and am not sure how that would be possible. Have you done this at all?Comment

There's only one reason I've ever seen that causes the paper to wrinkle on these machines, and that's a dirty fuser entrance plate. Take the plate off the front site of the fuser, (2 screws), and clean the ridge of toner that has built up on the very edge with something that can chip it away, then clean the rest of the entrance plate with D-ink or some cleaner, keep in mind that the hotter the plate is the easier it is to clean. It doesn't seem to mention in the original post that the paper was wrinkling, but it would also explain the duplex jamming problems, because if the paper gets skewed passing through the fuser, it can cause Duplex jams. If there is a bad toner build up on this, you probably want to check out F6-21, and make sure it's set to -55, to keep the toner levels lower, also change F6-26 to 0. Hope this helps, Good luck.Comment

I don't believe the paper to be wrinkled on the machines that are duplex jamming, it was just another question I had. If they are though I will make sure the guys are aware of it. Thank you.Comment

Still having a problem with this machine and J82 jams. Here is a picture of the jam still in the machine:
The bottom sheet you can see in the picture is basically hanging loose at that spot. So far the tech has done everything in this thread to no avail. At this point the tech believes its another clutch inside the main drive unit. Also, he was wondering if anyone has had problems with the stepper motor that drives the turnaround rollers? Thanks in advance!Comment

i've had many many problems like this,
however looking at the picture it looks like the fault you r having is relating to the fuser exit solenoid.
if u make a copy from the glass the paper comes out of the machine face up, (like in the pic above)
if u make a copy from the doc feeder, u will notice the copy comes out face down
so looking at the picture, to me the paper should come out of the fuser exit and straight out of the exit of the machine & not down into the inverting unit
i suggest removing the rear cover, then the pcb and replace the solenoid that moves the paper direction guide (its the bit that has black plastic fingers on it that have to be moved before removing the fuser unit)
p.m me if u need any more help

I would also like to mention the machine will make a few duplex copies before jamming, it doesn't happen on the first one.Comment

Peanut,
We thought we had it fixed after switching out that solenoid. We ran almost 200 duplex copies through the machine without a jam (it use to happen around 25 before). Upon duplex printing to the machine however, J82. This morning we ran some more duplex copies through the machine and it didn't appear to jam, it did however do something else that has happened before. It stops in the middle of a job and says 'Please Wait'. It has also happened when running out of paper and that was the case this morning. You install paper in the machine, shut the tray, and the machine will just say please wait and never resume copying. If you open the bottom left cover/access door there will be a sheet of paper that appears to have fallen from the turnaround rollers. Just like when getting the J82 code.Comment

Many of the problems I've had related to the inverter have been solved by one of 2 things. First if you remove the inverter, on the entrance of it, (the wide side), if you look on the inside, where the 2 plates meet at the top, there are 2 feet, one on the front, and one on the rear, that are semicircular. If those are not in contact with the other metal plate, then you can loosen the 2 screws on either side, and push the 2 plates together until the feet contact the other side of the plate. This will allow for more pressure between the inverter rollers.
The other thing I have found successful, and also a very easy fix is: I've have found customers who will try to move the copier with the finisher attached, they pull on the finisher, (you can usually tell if the plate on the exit door is slightly bent), I just take my fist and give it a good thump or 2, first on the plate to straighten it up, then on the lower front side, (the side that is normally bent), under the plate, with the door closed, to try and bent the frame inward slightly where the pin for the exit door enters it's hinge.
Hope this helps, good luckComment

We have narrowed down the problem to the unit circled in the image below. Replacing parts inside the unit has not worked for some reason and we are wondering if there is someone on here who may have this unit available complete and working either new or used that we could purchase. Panasonic does not sell this unit as complete, just parts. If anyone has one, please pm me or let me know and I will be in contact with you as soon as possible.
Thanks!

Can i just check, if you copy 200 pages from the platen glass, single sided does it jam?
why i ask this is because i want to elimate the fuser exit turnaround solenoid, its job is to direct the paper down into the inverting unit, but if u copy from the platen glass (singlesided) the paper goes out through the exit of the machine and bypass's the inverting unit
