Ricoh MPC5000 ADF Keeps Jamming

[zerokoo149]

Someone in my office was using the ADF to scan, and had a paper jam. They somehow pulled the paper out with so much force that they broke one of the gears on the cam stopper. I was able to glue that in and it's holding fine while I'm waiting for a replacement.

My problem is that now even after the gear is fixed, the unit still won't pull paper through the ADF, it jams every time. I recorded it to show how far the paper is getting:

I can't find anything else that is broken, but obviously it isn't working. What should the next steps be for diagnosis? Before the person in the office pulled the paper out, the ADF was working just fine.

Thanks,
Russ

You can start by posting the numeric jam code. That will tell us a lot more than a 4 second video.

Sure thing, the jam code is "J003".

I thought the video would be helpful to show at what stage is jamming, but I can see where the code would be useful too.

Re: Ricoh MPC5000 ADF Keeps Jamming

The video shows the trail edge of the paper. The jam is occurring at the lead edge of the paper. J003 on this model is a lead edge separation jam. Either the paper is hitting something immediately after the feed belt/separation roller, there is a problem with the separation sensor or there is enough paper lint on the black reference for the separation sensor that the sensor cannot see the paper. Sensor is located above the paper path in the ADF cover.

So I cleaned all 3 sensors in the ADF cover. At first I tried compressed air, and then when that didn't work I used a q-tip with a small amount of rubbing alcohol. That didn't make any difference. To give an idea of how far the paper makes it before it stops, it's approximately at the non-motorized rollers in the ADF cover.

All the rollers that are motorized seem to be running and run for about a quarter of a second and are just slipping on the paper after the paper stops until the jam message comes up on the screen. It's like the paper is hitting something and stopping. I don't see any obstruction though, and the leading edge of the paper isn't damaged from hitting anything.

Thx!

Have you done an input test? With nothing in paper path and no visible signs of paper hitting an obstruction that would be my next step. Also worth trying to feed paper SEF to see if it makes a difference.

Compressed air can be used to clean the black references located in the openings below the paper path. On some models i is a black felt that collects paper lint on other it is just a dark space. Photo sensors should never be cleaned with alcohol on any other chemical solvent.n It clouds the lens which can destroy the sensor. Use a soft cotton cloth dampened with water only.

One other possibility is that you still have a problem with the stopper assembly. If it is not releasing properly, the pickup roller will still be on the paper causing excess drag.

the two sensors mounted on the cover could be dirty, or someone mounted upside down, either the belt bearing, or the plastic belt holder (?)

Thanks for all the input, still haven't figured this out. To respond to the posts:

I did a SEF and it didn't make any difference, still stops at the exact same spot on the leading edge.

I didn't know alcohol would be bad for the lenses, thanks for that information. Definitely won't be doing that again. None of the sensors in the pickup area have black felt, but I did clean the one on the lower area of the ADF behind the white velcro board.

I don't know enough about the ADF function to know if the pickup roller is releasing on time, but I can say for sure that it is definitely still rolling the whole time, even after the paper stops.

The sensors haven't been removed, so I don't think they are upside down. I've also cleaned them multiple times so far now, so that's probably unlikely too. The belts have decent tension and I don't see any cracking or any other signs of stretching on them. I'm not sure what the belt bearing is to check that.



Also, I'm not sure if it's supposed to, but when I manually move the pully with the belt on it, the rollers spin as they are supposed to. I did however notice that the roller that is directly under the pickup roller is spinning in the opposite direction, I assume that is to keep more than 1 piece of paper from feeding at a time, but I also figured it's worth mentioning in case I'm wrong.

Re: Ricoh MPC5000 ADF Keeps Jamming

Thanks for all of the input. I tried everything that was suggested, to no avail. To give some additional answers to the questions:

I have tried feed the paper SEF, but doesn't make a difference. I'm not sure of how to do a input test, and can't seem to find anything online that tells me how to.

I didn't know that alcohol would cloud the lenses, I definitely won't use that again. I'll either use compressed air or a clean q-tip with water in the future.

I don't see any black felt in the upper assembly of the ADF that I could clean. There is one in the lower area behind the white velcro board, I did clean that one and that sensor.

I don't know enough about the ADF to know when the pickup roller is supposed to be releasing, but I can see that the pickup is rolling the entire time until the error is thrown, so I'm not sure that is what is causing the issue.

the two sensors mounted on the cover could be dirty, or someone mounted upside down, either the belt bearing, or the plastic belt holder (?)

I've cleaned all the sensors that I know of, and I'm pretty sure they weren't mounted upside down since they are in the same position as when the problem first occurred. The belts themselves look good with no signs of wear, cracking, or stretching. I'm not sure how to check the belt bearing though.



Also, one thing of note. The roller directly under the pickup roller is going in the opposite direction from the rest of the rollers. I'm assuming this is to prevent more than 1 piece of paper from being picked up at a time, but in case I'm wrong I wanted to mention it.

Thanks,
Russ

Re: Ricoh MPC5000 ADF Keeps Jamming

By your short video, I would suspect that the ID10T that had the jam, did not open the cover to remove it. Don't exactly remember that feeder, but looks to me like you have either a flipped mylar or something blocking the path. Take off back cover and manually turn transport rollers to see if it feeds through. If it does, likely sensor issue or ID10T damaged a clutch or something. If you manually can't feed, you have blockage like a flipped mylar.

The mylar doesn't appear to be flipped, and looks to be in pretty good condition.

The paper always stops right when it reaches the driven roller. Just to try something else, I removed the driven roller and the paper got much further and actually started to roll around to the bottom of the ADF. It gets stuck there I assume because there isn't anything to push it through without the driven roller.

I don't see any way to adjust the driven roller and I don't even know if I'm right about that being the issue, but it's more information towards a diagnosis.

Just remove the cover from the front of the ADF feed section and you should be able to observe if the driven roller is actually turning. If it is but the paper is not moving then the weight of the pickup shoe on the paper is creating enough drag to prevent the paper from full engaging the roller.

I might be saying the wrong name, the roller I'm talking about isn't motorized. It's just a free-turning set of rollers with springs on either side to keep downward tension.

I am taking about the roller that those are spring loaded against. For most Ricoh ADFs that roller is belt driven from the front. Take the front off and watch it. About the same rime that the pickup roller in the feed shoe stops turning, that roller should start turning. The feed belt feeds the paper against the roller. If the roller turns but does not pull the paper on in try changing the buckle with SP6-006-003. Default is 0 and can be increased to up to 5. This is a work rund until the actual problem is corrected.
