[Jamming] Toshiba e-studio 283 jam code e920 only when duplexing.

[Way Back]

I have a 283 that is showing the jam code E920. I have replaced bridge transport sensors 1 & 2 and verified that the solenoid on the bridge was working. Then I found out that it only does this while duplexing Letter size paper. It might run 10 out of 50. It does not jam on Letter-R, which is in the bottom cassette. Has anybody seen this or care to share what this old man is over looking.

E920, E930 0r E940 errors then this points to the bridge sensors causing the problem. Don't waste your time trying to clean them. Just replace them both. The part number is the same for both.
PN# 41321248000 photo interrupter.

While you are there, take a look at the exit sensor's actuator in the fuser. The old style actuator bubbles out from heat and if it bubbles out big enough it will hang-up intermittently causing exit jams. You'll know what I'm talking about when you look at it. It almost looks like it is made with a bulge in it, but you can take a file and file it flat on both sides again and it will work.

I have replaced the bridge transport sensors and checked the solenoid for operation. Strange thing to me is that it only does it while duplexing.?.

It is most likely the bridge gate solenoid if you have ruled out the sensors, the solenoid will appear to be working but it is not working correctly, it is intermittently firing at the wrong time, I have seen this a couple of times, it will drive you crazy and make you scratch your head a bit, but replace the solenoid.

I switched the bridge from a working machine and it still had the same symptoms. I switched the letter paper to the lower cassette and it worked without jamming. Strange. Not the kind of fix I like

I have the same exact problem going on and have tried all the things you did with the same results. Did you ever figure out what the problem is? If I do I will let you know.

As well as all the other suggestions, check the Pivot Post on the L/H side of the Fuser Cover isn't bent, as this will inhibit the movement of the paper when it is pulled back through the Cover to complete the 2nd side.

have you tried duplexing without the bridge unite/finisher attached?

No, sadly I did not. I figured I would stick with the lower drawer fix and not interrupt the office environment until I had to. If you do come up with a fix for it please do share it with me.

Yes I have and it works fine without it.

I did check the pivot point. I have had to replace that on several of those models. You are right about them being a problem. I have had several break loose and get very wobbly
