This is a very strange occurence... I have noticed this on several machines now, but there seems to be no rhyme or reason for it. The paper will come out of (virtually) any tray (I have an LCC on this machine, and had one on the previous problem machine as well) and then completely EXIT the machine before the e-550k comes up, asking me to open and close the middle buckle door... Sometimes if you open and close it, the machine will reset and try to feed again, but most often, it will not even clear before you power off and back on. The machine didn't ahve this problem prior to my removing the LCC paper feed unit and replacing the rollers, so I wonder if it has something to do with that? I went back and retraced my steps, but the same problem happened. I'm also wondering if it has something to do with that buckle/jam clear door in the middle, above the LCC, since sometimes the machine won't clear the jam unless you open and close it several times. The machine has had the HDD reformatted and also has the latest firmware... HELP! Thanks in advance!

Re: e-Studio 455/456, e-550 jam code...
This is the Ricoh style LCF. There are quite a few things that can cause trouble on these LCFs. E550 is multiple feeding so I'll stick to those:
Check the separation drive gears, viewable from the right side. They can strip out. This is not a great photo, but the gears in this photo are stripped.

Also take a look at the loop adjustments. There is a bulletin that has good guidelines, but each machine is unique and might require some additional tweaking.

1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.

Re: e-Studio 455/456, e-550 jam code...
Thanks Black Cat.. yeah, I use the Ricoh rollers in these units because they're a fraction of the cost of the Toshiba rollers, for the same part. I did put new rollers in the LCC, but the problem also occurs from other trays as well, not just feeding from the LCC. I've seen those little gears strip on the older machines as well (KD-1012), so YES, thanks for the update. I was recently advised to replace ALL the known defective sensors in the machine, with the new "grey" style sensors, so I ordered them all, but ordered only 8 when I really needed 11... oh well!Comment

Re: e-Studio 455/456, e-550 jam code...
For us the sensor usage has tapered off. Apparently most of the sensors that were going to fail have done so.
There are a lot of jamming conditions on this platform. If you have other jam codes please specify. We seem to have figured out the worst ones, but this is not some of Toshiba's best design work. The 452/453 platform was pretty reliable, but got cheapened up too much in it transformation to the 455/456/457.
Another common thing to look at on the Ricoh LCFs is the drive assembly. The clutches need changing occasionally or the wiring breaks. The problem arises when re-assembling. Some techs install the bronze bushings from the outside of the pack. This allows the shafts to shift 4mm to the rear, disengaging the adjoining gear, or disengaging the aligning tab which then breaks the wires. The bushings must be installed on the inside of the pack, then the pack frame over that.
If you notice the the rear of the pickup assembly is loose, the plastic alignment pins into the rear frame break. =^..^=If you'd like a serious answer to your request:

Re: e-Studio 455/456, e-550 jam code...
Thanks again dude.. I only knew about the one way bearing/gear that's behind the feed roller failing.. didn't know anything about clutches on that series. In contrast to you, I've had a TON of problems with the 352/452 series.. they have eaten my LUNCH! lol. I wanted to let you know that I replaced only FOUR of those 11 sensors on that box, and VOILA, problem appears to be solved. I replaced the buckle door (2) and the aligning/registration sensors (2) and that seemed to do it. I went for those first because that was the area that the machine showed the jam in after the paper had exited, so it seemed sensible. And I guess the sensors were old (probably the S/N is an older machine) but the ones I replaced were GREY in color as well; hardly any way to tell them apart.Comment
