C280 J-3003

[orestesp]

Hi everyone,

As I was printing a couple of hundred questionnaires on the C280, there would be an intermittent J-3003 jam with the paper jamming at the 2nd transfer roller. It appears to be happening at random intervals, and it doesn't happen with short run jobs. The machine had been working continuously for 2 hours and the area around the fuser had become hot to the touch (nothing extreme though), if that matters at all. The paper would get folded in a z-fold pattern at the 2nd transfer roller. Sometimes though whatever is causing this I assume also causes some sheets would come out heavily wrinkled, and you can hear some abnormal noise when this occurs.

I've read some older threads regarding that particular jam code suggesting that the 2nd transfer roller needs to be replaced, which normally I'd agree with, but the total counter on the machine is 135k! Which means that the 2nd transfer roller is nowhere near its EOL. I am attaching a few pictures of the 2nd transfer roller, maybe you can pick out what's wrong if it's there.

TIA!

Check if you registration roller bushings are not gummed up.
If its stiff to turn by hand remove vertical guide that houses the image density sensors and give it a good clean.

a Quick way to test is to put a small well directed and controlled amount of WD40 on those brass bushings.
Not suppose to put lube there but you will know soon enough if its the registration roller ends and bushings that
gummed up.

Could be something else.

Just how stiff to turn are we talking about? Shouldn't the reg roller be a little stiff to turn normally?

Re: C280 J-3003

On the xx4e series 30-03 jams can be caused by the exit section clutch CL8, or exit switch mounted on the outer door. None of my C360 series machines lasted long enough to get these problems, but that's where I would start. =^..^=

Yes a little more than what you would expect from those rollers.
Its got no clutch there and you will feel some resistance from the stepper motor magnets.

And they can last still willing to PM them at 2mil if it was a runner.

Re: C280 J-3003

Paper that has excessive curl may not separate easily from the Transfer belt and will contact
the separator claw. A jam may occur or the claw may be pushed into the Transfer belt creating a scratch or possibly a gouge.
There are parts modification. See attached.

Re: C280 J-3003

Same problem here - J3003 on long runs, sometimes... Have to go tomorrow. I has intention firstly giving a chance to WD40. Thank You tsbservice for pointing the issue.

Re: C280 J-3003

There should be a black guide that sits on the metal plate attached to the transfer belt. Its purpose is to assist paper in entering the fuser and stop lead edge flicking over the transfer belt. If this is missing can cause these jams, more often on 224 style machines but seen a few times on 280

Yes its just a quick check if that works or not you will need to strip and clean the shaft and bushings properly. The WD40 will loosen it but will be sure to gum up again in time.

O yea good point!

I don't see why this guide can be missing unless lazy users/techs decided to skip putting it back.

Edit: but it's missing there 😄

Re: C280 J-3003

There was burnt toner that presumably fell off the fuser onto the shafts of the reg rollers right next to their bearings. I did a quick clean up and added some WD-40. The reg roller had some initial resistance when you tried to spin it, but now it's gone. Otherwise it behaves the exact same way it did before.

Finally, there is only one finger on the belt, seems that the machine had been modified according to the bulletin tbs attached.

I haven't tested it yet but I may disassemble the whole reg assy and give it a more thorough clean. Is there anything else you think I should also check?

Thanks.

No. Your is UNmodified, new ones have 3 claws. Also you will need that black plastic guide - item 19

Sorry, I got confused and thought that having one claw meant that I'm good. Thanks for the advice, I'll check if there's somewhere to buy these parts..

**NOTE I wouldn't suggest using WD40.. it is not a rust preventive.. it is a WATER dispersant may I suggest you try Triflow oil.. it has teflon particles in it.. give longer protection.

If you need it to penetrate try Marvel Mystery Oil, but it vaporizes within a year and is gone.
