6020 ADF Paper Exiting Problem

[User Name]

Hey everyone,

I have a 6020 with a strange issue I can't figure out. When feeding paper through the ADF the paper goes through the ADF fine, makes the copy or scan without any issues and exits as it should, but sometimes as it leaves the ADF it sort of hangs there for a second (doesn't fall into the tray immediately) and the next page coming through runs into it and pushes it out of the way and sometimes off the machine.

I've tried changing the exit roller, the exit roller clutch, and both drive motors. Changing the exit roller seemed to improve it slightly. Anybody ever seen this before or have any suggestions on what to try next?

I should mention that this particular customer does more scanning than anything else and that this ADF has had over 2 million pages put through it.

Thanks in advance.

Did you try adjusting F6-87 (ADF exhaust stop position)?

I have now and it had no effect. Seems like a mechanical problem to me.

Did you also checked the spring loaded white pressure rollers above the exit rollers?
I remember having trouble because of them once...

Yes. I re-tensioned the springs and replaced the white pressure rollers and the plastic guide that houses them. I had this exact same problem on another 6020 about a year ago and was able to fix it by re-tesioning the springs but no luck this time.

It just doesn't make any sense to me. Everything works fine but the stupid paper just doesn't fall like it's supposed to. (And it's not because of the paper either.)

Thanks for the advice.

I've seen issues with the solenoid on the front side of the feeder, seems the gate binds, usually just flexing the front frame outward a bit is enough to free up the solenoid.

Aren't both of the solenoids in the front side of the ADF used only during duplexing? Although, I haven't tested the duplexing feature to see if it makes any difference. Next time I go for a round of troubleshooting on it I'll have a look to see if the solenoid is functioning properly.

Thanks.

Yes it is used for duplexing, but if the gate is sticking, or one of the arms are cracked, it could create a blocked path.

Oh, and another thought that just occurred to me, There's that black plate attached to the top cover, with the 2 mylars on it. I've seen where a nick will develop in the center of the plate, where the actuator falls through the hole, it will catch the paper as it's feeding through. Smooth with a razor, or sand it down, or just replace the plate and the 2 mylars.

And another thought is that I have only ever replaced the 3 clutches on the top of the ADF, I know that it was after the 30 series came out that they changed the Clutches to the newest style. Silver casing with Black print, if you have the black casing clutches, or worse the silver casing clutches with the white print, chances are replacing those clutches will help your feed. the two clutch part numbers are L9EAAJ000026, and L9EAAJ000028, (if memory serves).

Checked all of the solenoids and guides, and there is nothing in the path that is blocking the paper.

All of the clutches are black clutches, if my memory is right. The clutches that you are referencing, I'm fairly certain, are not the issue. I could update them, but I doubt that would help. And just to reiterate, the paper does not get caught up on anything or have any issues when making copies or scans. The only issue is upon exiting. The paper doesn't fall from the ADF as it should and the next page in line pushes it out of the way or gets underneath it and messes up the order of the pages of the document being scanned or copied.

Thanks for the advice.

Have you tried removing the clear plastic tray under the ADF? I have seen the clips on the back break and fall onto the tray, causing the pages to hang.

I just had a service call outside my territory, the ADF was doing pretty much as described in the first post, I replaced the clutches and was good to go. The first thing I do after checking the tires on these machines is make sure the clutches have been updated. The reason they changed the clutches was because the black ones are known to fail. If a clutch slips, it can affect the ADF's timing, causing a jam to occur because the paper didn't exit fast enough.

It isn't that.

I've given up and switched out the ADF with another one and that one is working fine on the customers copier, so I know it wasn't caused by any settings in F6.
The ADF DIDN'T jam and the copies from the ADF were fine. This makes it hard for me to believe that the clutches were the problem. Although I'll admit I did not update the clutches (I replaced them with used ones from parts machines), so maybe it is the problem. I don't know anymore. I have the ADF at my shop, so I may try updating the clutches when I have some time to spare to see if that solves it.

Thanks to everyone for the suggestions!

Why thank you Mr. Shower Salesman. Do you often find yourself having to fix copiers while selling showers?
