C3350i J-1101 J-1102

[allan]

Hi guys.

This C3350i machines are driving me mad. Getting paper feed jams where the paper will go past the registration section and jam infront of the fuser giving J-1102. It seem that it does not detect the paper leaving the tray else i get J-1101 where the paper gets stuck at the registration roller.

I have changed out both the feed and registration clutch and the paper feed and registration sensor.
What am i missing here?

Also the on the DF it does not seem to eject the paper completely.

Any help will be appreciated.

The df has a bulletin on the exit gear and spring. as far as the feeding goes i have replace the entire feed unit to get rid of the 1102. they had some bad clutchs.

here is the bulletin

This is the right solution.

That is the real cause, I am sure about it

What he said I have tried piecemeal to no avail. the whole unit seems to be the answer.

Hey thanks for the bulletin. That one is to fix an image quality issue.
Do you have the one for the paper exit issue? That would be super handy.

Hey thanks a ton for the docs.
Unfortunately not the issue with these 2 machines. The readings are both less than 3K and about 2 years old.
The rubber dampers are in perfect shape.

I don't like the idea of a plastic shaft used on the separation roller assy on tray. It makes a screeching noise when feeding. The separation roller seemed a bit stiff to me, but after changing the limiters and springs the result stayed the same.

Always the small machines that gives me hell. KM can not figure out an A4 footprint machine. Why??

That's why they desided to go with Brother(bizhub 5020i)

If cushion is OK. Check the spring under idc sensor cover.

Re: C3350i J-1101 J-1102

So two things that works against it. The plastic shaft on the separation roller wearing down the thinnest of layers and causing friction, grease is working until i can get it replaced. Then the restive registration sensor that is explained by the bulletin to be out of position causing the paper to stop for registration before its past the middle of the roller. Fixed that by sticking another 2mm of padding on top of the perfectly good existing padding.

Arrg its one of those fixes i just can't trust. Well its working for now.

Now just the DF issues where the paper does not get ejected completely.

That option is just to expensive here in ZA. Not paying $300 for that complete part.
Think its the stiff separation roller that makes the clutches fail.

I agree with you on the df force, the entire i series has very tight double feed prevention systems.

Re: C3350i J-1101 J-1102

For the DF not ejecting the paper I found that there are 2 metal cam plates that separates the exit driven and driving rollers so that the paper can be removed from the platen side.
The metal plate cams are connected between the exit driven rollers and the flap to remove jams from the bottom. They get bent and worn ever so slightly.
Filed the worn areas and bent them back to shape and seem to be all ok now.
