e-studio 25s paper jam

[paspar2]

Hello,

My trusty old 25s has started to consistently jam paper right inside the side door with error E01. To clear it, I need to open the duplexer, open side door, remove the paper which is always right there near the drum and folded in half on its way in (or is it out?), then open and close the top 2 doors (never anything there but the unit asks me to do that).

Im not a tech (ask you can so plainly tell from my non tech language) but its obvious that something isnt rolling... is the drum supposed to be hard to spin manually - I tried to spin it via its gears (on the right side) and it doesnt spin... It does spin with the power off.

Also tried to remove and reseat the "processing unit" (called this way in the service manual), followed the instruction to remove it but needed to pull a stainless pin held in via spring to get it out which was not mentioned in the instructions. re-seating didn't help anything.

Could someone guide me with testing procedures?

thank you

at a guess id say the gear on the fuser heat roller is broken, if its not making it in to the fuser. best of calling a toshiba dealer, not somthing it recommend a end user to fix.

If this gear is broken, will a new processing unit or "drum kit" fix it?

I don't think a new "drum kit" will help you here. When you remove the jammed paper, is there an image on it? If so you can probably say the drum is turning fine. Its the gear on the fuser unit (hot unit above green roller which you shouldn't be touching) that is common to breaking up. I'm pretty sure if you can work out how to take the fuser unit out, you will be able to fault find this much better.

jonezy999, there were images on the papers... not dry yet and smudged very easily. I am probably confusing term here but the "processing unit" aka "drum kit" (as far as I can tell from reading up) can be removed via the toner "door" .. can you give me some pointers about getting at the fuser unit? do I need to open up the back panel of the machine (not at the machine now but gathering info for tonight)

if that is the issue, would I need a gear set? a whole fuser unit?

thanks!

Been a while, here goes from memory.
Open duplex door and remove RH rear cover.
Remove (I think) 4 connectors.
Remove 2 screws and fuser unit is out.

These fusers use plastic bushings on the rollers which in my opinion shrink under the heat after a while causing the rollers to get harder to turn, also the gear becomes brittle with age and heat. Once you get the unit opened up, you will see what needs replacing.

iv always thought its the exit unit getting tight which causes the gear to break

Wouldn't be the first time I've been wrong, duplex drive also causes problems on these.

CORRECT!

You were spot on! the orange gear fell out in pieces when I took the fuser unit out: http://i56.tinypic.com/2s964gi.jpg (not able to insert image for some reason)

now the question is, can I purchase just this gear and how do I refer to it in my search
(what "name" does it go by)?

also, this piece: http://i54.tinypic.com/1115zjl.jpg fell out of the fuser but I cannot figure out were it goes back.. its around 2" long and had 2 tabs but they broke off the minute i touched them - this piece is dry and brittle so it was close to heat for a long time...

another pictures for ref of the entire thing: http://i54.tinypic.com/rcu9va.jpg

Thanks for all your help!

If you plan on keeping this copier for awhile, I would ceertainly invest in a new fuser. Usually by the time the gear breaks, other things are wearing down also. My guess is a fuser will be around 150-200 dollars

[paspar2]

If I can get this gear for a few bucks then Id go that way. The copier is old and although it worked for a while, I get the feeling this is one of many things to come

For example:

I did notice that those "teeth" looking things that are resting on drum inside the fuser unit (the drum that has the quartz tube in it) and are held with small springs - 2 of the 6 are missing one of their hinge pins the let them pivot (not sure what its called) and they dont rest squarely on the drum, but are off to one side - does my description make sense? are those important or can I remove 2 of 6 or even leave them be off kilter like that?

Don't worry about the bit in your 2nd pic, it wont effect performance. The 2 claws you mentioned can get knocked out of position, if so, put them back in, if they are broken you can usually get away with evenly spacing the remaining claws. Either case, you're best NOT just leaving them how they are now.
Google these

Thanks for the part numbers... I did google some last night and found this parts catalog DP16_20_25_PARTS with different part numbers that lead to the same items

Will google more today but first hit was $30 for that small plastic gear - seems obscene (to me anyhow)

Is that bushing you mentioned on the opposite side from the gear on the fuser?

thanks again for your time.
