Re: Bizhub 454e

I had one doing something similar a little while ago. In the end it turned out the main body exit was binding causing a timing error when a finisher was fitted. I stripped & lubed the exit bushes and it's been ok since. Might be worth a try since you've already eliminated the finisher itself.

Tech51 ....this the internal finisher...paper never exists at all

I know it's the internal finisher, so was mine.
If you read my post properly you will see I was referring to the main body exit, not the finisher exit.
As I said it's not a definite fix, just something to try....

There's a bulletin about doing this to fix the problem, the only thing that worked was using "dry surf", i stripped it a few times and used different lubricants, until i tried the "dry surf"

Re: Bizhub 454e

Did you ever resolve this Antone?

I would be interested to know what you found.

Thanks..

Re: Bizhub 454e

Just following up on this. I followed a tech in on this exact problem today. He had also run the finisher on a different machine with no fault but couldn't make it work on site.
I stripped & lubed the main body exit and then ran 500+ prints with no further issues. It confirms my theory that its a timing error between the main body exit & the finisher unit.
Hope this info is useful to someone in the future.

Re: Bizhub 454e

What jam codes? I have a FS-533 in my trunk that was making 72-17 jams today. =^..^=

Re: Bizhub 454e

J7217 and sometimes j7219. I've only had it happen when fitted to a C454e. I'm guessing the extra speed causes the timing issue.

Re: Bizhub 454e

I spent 4 hours with this FS-533 today and took it to down the frames. Everything turns freely. There was none of the heavy tar-like black grease that the Toshiba internal finishers have. About the only thing I could identify was the timing was off on the upper exit roller lift. Naturally there is no explanation of the timing marks on the gears. But in the Theory Of Operation FS-533 section there are some good illustrations, and if you blow them up to 400% you can see the marks.

Once reassembled I ran 750 pages through the finisher on our in-shop 284e, so I had that really good feeling. When I took it out to the customers location it jammed on the very first page. If you duplex, the first side passes, then jams the duplexed image in the stapling tray every time. Still J72-17.

As plans go, I could take the other internal finisher out to the customers location to see if it jams too. Or I could order an MFPB.

i have this problem currently on a c454e. I actually swapped out a finisher from a different machine and still got first page jam 721-17. and old finisher works fine on another machine. My theory is the fusing unit exit sensor or rotation of fusing unit is failing causing timing to off when it gets to the finisher. I wouldnt change MFP until i change the fusing unit fusing motor, and paper exit assembly. Those parts cost way less and easier to get. Ill update when change fusing unit.

It's the machine exit that's the problem, nothing to do with the FNS , there's a tech bulletin TAGB1600344EN, that tells you what to do, i try a couple of times to strip/lube it, it only worked when I used drysurf

Taking one of those down to the frame is no easy task. Reminds me of the old analog days when repairs were incredibly labor intensive. You were faster than me at 4 hrs.
The time I tore one down to the frame for a jamming issue all I could come up with was a sticky solenoid plunger. It was the one below everything near the bottom frame. Don't think it was the same jam code as the one in this thread.
