[Jamming] Taskalfa 3252ci keeps jamming J0511/J0518

[Alkeros]

I have a TA3252ci that keeps having paperjams with code 0518 and 0511.

I have already tried:

-replacing the feed rollers
-replacing the entire paper feed unit
-reducing the spring pressure on the retard roller
-a new fuser (because i read on another post that this could help)
-another brand of paper

i tested 150 duplex pages and it didnt jam, but now the customer has called again saying the issue isnt gone.

Any ideas what this could be?

Seems like you covered all bases did you check Registration sensor, Duplex sensor, duplex clutch may be weak, How many drawers does this machine have? WHAT is total page count on the unit? Do they have this problem with every paper source or one certain area?... Did you try a Firmware update... sometimes its a last resort when all else fails.

i havent tried the clutches and sensors yet, . the machines has 4 drawers but its only from the first one. The total count of the machines is 518805 which is not that much.

So if it's only doing it from drawer one, you have your answer. If you set drawer two, three or four the same way that you have drawer one and none of those issues happen with jamming, then you need to replace the feed clutch for drawer one.

You can drive all the components in Maintenance Mode so start troubleshooting and list some actual observations.

Works better than being a parts cannon (pow pow pow)

I had a machine like this give me recall after recall. I'd clean the rollers or replace the rollers and it would work. Then a week later, the same thing. Then a week later the same thing.

My machine was dumping black developer into the front cover. Every time you opened/closed the tray or opened/closed the front door, it would dump just a little more black developer onto the top page in tray #1.

The quick test?: Remove the top piece of paper and re-close tray #1. Bang on the front inner cover. Look at the top sheet of paper again. Is it covered with developer? To properly clean up that developer, the front inner cover has to come off ... and deal with the black developing unit. No, there was no discernible quality issue. =^..^=

Try turning the affected cassette to letter R. I have found this to be more forgiving and if that works without jamming, I have found it to usually indicate clutches or a timing issue.

ill try this tomorrow, but today i discovered that the problem occurs in every tray. i'm becoming a little desperate.In the maintenance mode all the sensors and clutches respond . today i even changed all the clutches in the side panel AND i changed the complete feed drive (parts from another machine) + i also did a firmware update.

But the customer called again saying they had 2 0511 jams

That's so awesome, and the first time I have seen the new "Observational Logic" from the Service Manual put to use. Long story short, if you look at many J05xx troubleshooting steps, one of the first is "Check for slip mark on paper". This is because there is no PF sensor until you reach the Reg roller so you can only tell whats happening by checking paper location and condition.

So the Event Log should now show 0512,0513,0514 jams as those correspond to the different trays.
Single point of failure for all trays is the PF Motor, gear train, or Feed Drive PWB

Check to ensure the replaced PF unit is fully seated against the rear frame, as it can be installed with the alignment pins not fully seated in their holes.

When you check a CLUTCH, you must turn on the MOTOR button (Drives PF motor) and then hit the CLUTCH button while observing the rollers with TRAY 1 removed. It will only rotate for 1-2 seconds.

The panel button turning blue only means the controller sent the signal, it doesn't mean it actually worked.

I remember a machine where the tech swore the PF clutch pack had been replaced, but every bushing was coated in oil. They had oiled it up and it leaked to the clutch faces.

sorry if im being ignorant but does this all matter after i changed the clutches and the pf drive. Because after i changed all this i did 200+ duplex prints without a single jam. Its just so weird that the clients had these jams and dont.

+ the jams also occur in the 3rd and 4th tray

The longer it goes on, the further the developer migrates down through the machine. It's possible to begin to affect trays #2 & #3 as time passes. Let us know what you find. =^..^=

Saw this bulletin today

Thanks Eddie, that looks useful. =^..^=

Re: Taskalfa 3252ci keeps jamming J0511/J0518

0511 double feed from tray and 0518 double feed in duplex?

I've seen loads and usually it's just really badly cut paper so all the sheets are stuck together in the pack. I could understand the bulletin fixing 0518 but not 0511 if your only doing single sided then your not using any of those clutches on the door.
