[Jamming] ir3570 persistent jam on PS10

[doc1479]

Hi everybody,

I hope somebody can help me here, as I'm running out of ideas.

I have an issue on ir3570. It constantly jams 0101 on ps10, either stationary or delay.
Paper is always stuck half way through the fuser.

Unit already got gray vertical path rollers (FB6-4852) and upgraded lower door assy (FM3-1296).

I've put new registration sensors (FL2-6580) and swapped pickup assemblies around. I've also removed dumper on ps9 and cleaned the sensors. Same story.

It prints/copies fine from manual feed, so I've ruled out any fuser related issues.

It has old style preregistration flag, no metal jacket, but hardly any wear (15mm), so I don't think it needs a replace.

Any thoughts ?

Thanks,
John

Does it jam every time from BOTH cassettes? On A4 & A3? (Or your country paper sizes)

Dont rule out those old style flags even if they look ok can still be worn enough to give trouble!

Re: ir3570 persistent jam on PS10

Yep, both cassettes everytime. A4 and A4R. And I`ve checked dials, they are set correctly.
I'm tempted to replace pre registration flag as well. Just wondering if there`s anything else worth trying.

Cheers,

If the bypass is fine then i'd be looking at the top feed unit, maybe the one way clutch on the end of the grey roller shaft.

You can swap those two feed units round, just swap the brackets, that would be worth a try

Thanks for suggestion. I`ve tried swapping feed units already. Still getting stuck even if copying one page.

There is a pad on the back side of the registration switch that can get sticky, also remove all pads on the door and around the fuser.

Hi Rob,
Yep. I`ve scraped that one off already.There is a replacement FC0-2118-010 for it too, but its 4 weeks lead time from supplier atm. So I didn't bother yet. Whereabouts are the other pads near fuser thatyou`ve mentioned?

Thanks,
John

Above the fuser there is a deflection gate for the duplex, there are 3 pads under the gate fingers and 4 pads on the inner swing out section. There are also 4 pads under the gate on the door. None of the pads need to be there, they are just for noise dampening, I hope this helps.

Cool. Thanks Rob. Sounds promising. I'll check that out and report back 8-).

If the machine is jamming every copy then you can rule out the sticky pads, they only cause interminent jams, usually first thing in the morning & you say the bypass works fine so you can rule out the registration sensor.

Replacing registration sensor was next on my list If it's not the pads or the sensor, what is left to try ?
Error is always 0101 on PS10 stationary, or delay 0201 if it's from the second drawer.

Re: ir3570 persistent jam on PS10

I have a feeling the registration actuator is your problem even though you say it's barely worn, it doesn't take much to mess it up. I have actually been able to bring the bracket the lever sets in closer to the front but you have to be careful because too much and your lever will not be able to move in the holder properly. I had a machine just this morning that was jamming every time just out of the fuser and it was those darn pads!

If the paper always stuck up in the fuser, grease the fuser (with the proper grease) to ease the the film circulation, it happens to me every time.

I'm waiting for parts to coming at the moment. Will be on site next week again to replace the actuator. I will check out the pads you've mentioned as well.

As bypass works everytime, I don't think it's fuser-related.

Re: ir3570 persistent jam on PS10

I was working on a 4570 this morning so I took some pictures just to show you where all the pads are, it's good to get them out of there even if this isn't the fix for your present issue. There are four pads under this guide approximately where I've circled.



You can't see it really well, but this is one of the pads



There are seven pads on this piece.



Also, if you have this build up you should clean it with alcohol



You don't have to go wild, just clean the ridges and where paper contacts the plastic, like this



These two one-way bearings can give you jamming issues also



I hope this helps.
