8000i constant J1313 1314 Tray 3-4

[habik]

Hi have new beast and new hassles too.


200k it has done, cleared all the sensors on paper path, tyres on tray 3-4 have 50%wear out as predicted by being half way through to PM.

Tray 1-2 has done more copies than 3-4 and has no jam.

Haven't tried yet the bridge unit shafts/bearing cleaning, as tray 1-2 are running fine until today. Suspecting timing issue, a.e. sensor / clutch in between tray 1,2 and 3,4..

any suggestions?

hi there,just had the kyocera rep down for exactly the same problem i had spent three days trying to figure it out and like you i thought it was either the sorter or the bride unit (so did the kyo rep) .we decided to remove the bridge motors and check them and to do so we removed the exit unit on the machine .while i removed the motor unit from the back the kyo rep looked at the exit unit.he found the bearing on the end that the belt is was tight .we removed the bearing (had to use flat blade to lever it off).it was so tight the shaft had a blue tinge on it where it was overheating.we cleaned of the black grease and used very fine wet and dry to clean the blue area of the shaft .put it all back together and got 1000 stapled booklets through with no problems and its still going (touch wood) hope this helps you

Thanks I have already read that thread and as I mentioned above, It does NOT jam from tray 1-2 at ALL...only tray 3-4 ..which doesn't make sense.

I will clean the bearings and shafts in bridge anyway!! Thanks tho.

I had the same exact problem on a much newer machine, the kyocera rep and i found the clutch on the vertical conveyance section was rusted and very dirty, the roller it drives is right above trays 3 and 4 on the right side, you have to get it from the back and its not easy to get to but after dissasembling the clutch and cleaning it throughly the machine stopped jamming. hope this helps

Thank you Hosman!!

I have cleaned 1 clutch and it wasn't rusty at all and was not suspecting any other to be rusty. As the one you talking about is just next to the one I cleaned. The one you talking about is deeper in machine so that was why I did not intend to go there as 1 "New machine" 2, Already checked the one next to it which has more possibility to gain moisture. And they look as good quality built..

Great stuff. Will go and see the client tomorrow. And let you know.

OK Machine is now fully running after cleaning all of the clutches x6 in vertical conveying range. Few mods on support rollers (nylon) spring caps OFF. tray 1-4.

Sensed noisy rattly motor whilst testing.. Hope it won't go balistic in next 300k.

Here are some scans of jam codes.S25C-411111616050.pdf

Here some shots of the clutch and their locations.

Please make sure the harness that connects to the vertical feed clutch has some slack - known issue with it being too tight. This can be tested by tricking the upper vertical door and running U030 to see if the roller partially rotate - when they are not supposed to.

U32 is the mode you want for clutches,but U30 seems to work the same way

YES, harness been left with plenty of slack. from the beginning and if I pulled the cable back, it did not make much of a difference so this machine was lucky to get the right amount of wire slack in factory I know there is a mod to cut harness holder tip, that dips in to the mainframe.

Used few bulletins but not all were actually working. Definitely Support pulleys have to have smaller spring tensions.Have not fitted the 0.1 N as they are YET not available to me. However when you take plastic cups off(WHITE) it does its magic (it doesn't change the tension, but it does give the pulley a bit more room to float about and paper has more freedom.This will get you by on the J1313&j1314 for sure, Just a bit worried about the fact of not using the plastic caps for the new black springs, as it tend to slide the pulley to one side on the existing silver , causing miss-feed as the pulley tend to go against the plastic holder. Mainly for me it was causing a lot of J0523.


J6310 - used the bulletin but, I STILL haven't figured out how to apply the procedure, when there is a protrusion and hole on the plate so there is no otherway then the way it was pressed at the CNC machine. or just simply disconnect the sensor and it works anyway.OR hang on is that the fix to get the sensor OUT OF THE rotating wheel?

Luckily 4 me just a small number of jams elsewhere.

Now I have another worry, when I go for U031 to check a noisy motor where I was suspecting fuser motor it was actually a different one the DLP(K) VERY VERY BAD noise, almost like the rotor is out of balance. VERY unhappy customer. NO Solution to that one YET.

NO PROBLEMS YET with EJECT section (bridge section) so no rollers replacement for me for now.

OTHER THAN THAT Sweet machine, but very savour.

Sensors are very sensitive to dust, and unless you know where to blow( which doesn't always work) you have to dis-assemble a lot. And that is usually 1 hr just to dust off.. grrrrr
