Biz C224e misfeed

[copyman]

Has to be something simple & stupid I'm missing! Tray 1 paper stops at sep roller and has dent in middle of lead edge. Had two machines do it in one day. New rollers fixed the one but not the other.
Only 50k clicks on this machine that is still doing it after new rollers. Suspected sep roller tourqe limiter was tight and put a light oil on it but didn't help. Can't believe with all the "4" series I've worked on and never seen this. Could it be the the one ways? Only replaced the rollers because of low meter, didn't even take the one ways out. With higher clicks I remove the feed unit and clean or replace one ways, scuff up shafts, clean mag clutches with electronic contact cleaner, etc. But cheated here by removing paper drawer and just replacing the rollers.

Thanks in advance for the help

What about the mylar at the cassette?

Re: Biz C224e misfeed

if you remove the sep roller and load a single sheet of paper in tray does it feed through ok

Re: Biz C224e misfeed

Might not be relevant, but are you using the ribbed rollers or just the good ol orange ones?

Did you try to run any cardstock?

This account is close to my shop so will try this. Thanks

Yes replaced with OEM new style ribbed P/U roller & feed but machine already had a ribbed roller in it.

Funny you mentioned about card stock was going to bring some different types of paper to try.

That sep roller keeps jumping out at me as the problem. It seems really tight but they always do to me. Not sure if this sep roller torque limiter is tighter then normal? Was going to replace that first when i go back. If it don't work will report back with everyone's suggestions posted here.

Thanks again

Will check again but everything looked normal. First thing I checked was for obstruction, etc.

Thanks will let you know what I find when I go back.

Re: Biz C224e misfeed

I've seen the crumpled edge like that when the feed tire one way is slipping and the pickup tire is trying to push the paper between the feed and separation tires. You would probably see some sort of skid marks on the paper from the pickup tire along side the crumple mark if that were the case. At only 50K I really wouldn't think the one way would be the problem though, but I've seen stranger things.

I've also seen issues with overly stiff torque limiters like you were talking about. If you have a spare limiter I'd try that out first, as it's the easiest and fastest test, before resorting to removing the entire feed unit assembly to buff the shafts.

Re: Biz C224e misfeed

Agree with femaster. Easiest test ever I do to swap all 3 tyres, 2 oneways and torque limiter between 2 standard paper feed drawers. That should almost 100% work until I ger back with some parts. On high mileage machine I tend to swap all 6 pieces together when rollers are due.

Jam codes? =^..^=

Thanks Cat but jam codes will not help with this one. This isn't a jam rather a misfeed. Your eyes are jam code in case like this, consistent with paper stopping same place every time with dent in middle, never feeding out of paper tray.

Going to the customer's today and will report back what it was.

What about scuffing up the shaft where one ways go, I use scotchbrite pad? I always do this when replacing one ways.

Re: Biz C224e misfeed

Sorry, I don't know what the difference is between a jam and a misfeed? There should still be a jam code recorded. And all my database entries are based on jam code ONLY, not some visual of where a piece of paper stops. =^..^=

Technicians each have their way of troubleshooting and lingo. After 40+ yrs in biz my old school way of thinking is if paper has not left the paper tray / drawer / cassette (old school lingo) it's a misfeed. If out of tray far enough to reach transport / registration rollers it's a jam.

So in this case you look at jam code and it registers tray one "jam". Now what? NO help at all! This is where the troubleshooting begins and "visually" see the dent in paper and go from there.

Re: Biz C224e misfeed

Thanks everyone for the input. Turns out it was the Sep roller torque limiter. After confirming it was that I removed the PF unit and replaced one way's after scuffing up shafts. Already had the new tires I put in a few days ago. So now everything has been done and should be good for a while.

For all the US Technicians Happy 4th. God Bless America
