It doesn't happen all the time, but when it does jam out of tray 2 it makes a squeaking sound and throws jam code: 20-02. I have replaced tray 1 and tray 2 input assembly with a new one and it still happens. Anyone had any problems with this same issue or know a fix?

Here is the issue, paper coming out of tray 2 does not have enough drive to pull the paper out of the tray. The vertical transport roller has been updated to a grey roller but I have seen these still jam. I have been modding the side door to put more pressure from the white idle rollers against the vertical transport roller with great success.

Remove the plastic guide with the white idle rollers from the right side door (lower part of the door). Quite a few screws plus the lower door catch to remove. I have then scotch taped some Home Depot washers over 5 of the screw holes on the door then attaching the removed plastic guide and screwing it back on. The tape holds the washers and the screws punch through easily to reattach securely.

I recently revisited a machine I have modded back in August and there have been zero jams since.

Let me know if more description, part numbers or photos are required.

As for the squeaking, I have seen one where I had to remove the bypass assembly from the right side door and clean and lube the idle gears of the bypass drive. Very noisy.

The right side door assembly of the c224e through c554e seems weak. B&w the same.

Is there any way that you can provide some photos of the part you are talking about taking it off and a little more description on how to remove the cover to insert the washers.

Thanks,
John

Yes no problem, give me a little while to do a proper document for you.

The springs of the white roller have been modified with new ones with more pressure:

Please see the attached pdf.
I was fortunate enough to run into this issue again today so I modded it and took fresh pictures. Also note that the springs mentioned in HoonBoy's post are definitely in need of replacement which may have also solved the jam issue however I have not ordered any yet.

Thank you for the additional information, I just ordered the springs today to try and hopefully that resolves my issue. I called Konica Minolta Tech Support today just for additional information and they told me to try the springs first and if that doesn't solve the issue to replace the Front Side Board followed by (if the Front Side Board didn't work) the Printer Control Board, but I'm really hoping that the springs fix the issue. Thanks for the information.

Where did you come across this information, just wondering if you don't mind? I called Konica Minolta Tech Support today and this is the first time (at least the support specialist that I talked to) he has heard of this. I couldn't seem to find anything about this bulletin in the Konica Minolta database. This is definitely what I'm going to try. I ordered the springs today, but was just wondering where you came across this bulletin?

Springs ordered but on back order of course. Curious to know where this came from as well.

Why do they always go to a board when is is clearly a documented issue with these machines?

Well I replaced the three pulling springs with the new updated springs and that took care of my problem. Thanks for the information guys.

Welcome, glad too hear it worked for your problem.

This information came the document "Improvements in Service Productivity of Office Products V4" from the Konica Minolta e learning.

Thanks I found it. Good information in that document.
I admit I'm a little behind on learning as of late.
Odd that no I have spoken with has seen it either. I guess we are all too busy to keep up.

Thanks for this!

There is a modified conveyance roller for this range that also cures the J20-02.
I fit this roller and put the light weight spring into T2. Works every time and takes 10 minutes max to fit.
The roller part number is A5C1P00100.

Cut away two steps in the mylar that goes over the the two grey rollers.So the mylar must not make contact with the rollers at all. Replacing new pick sections won't help.

Only seeing this not after posting my own thread. Going to try issac's fix on the door. If not ill order the springs then the modded roller if needed. Getting a price of £44 for the roller so will try cheaper options first ;)

Edit: can anyone confirm the part number for the new springs as my supplier doesnt list them as a spare part.

I can confirm the part number as A64J815500, holding a bag of 6 right now.

Where you getting them from Colin? Our machine is the Olivetti equipment the MF282. Not often part numbers are different between brands.

Check out HoonBoy's post on page 1 of this thread. He supplied the part number. There was a KM online course for improvements that listed the part number. Not in the parts guide.

Just a little update, I modified the door with the washers as per Isaacs handy tutorial and it is still going great after a good few weeks now. Have the Springs to hand if it does go wrong again I will fit them to the door

I also use the black ribbed vertical roller and put the light pressure spring for tray 2 pickup. never had issues with that to date.

The soft gray roller in the late e series machines are not a permanent solution the feathered traction pattern wears smooth after 500k or so and you have jamming just like the first 4 series. I am replacing them with the mod roller now too.

earney
07-02-2015, 11:30 PM
Yeah we have the light spring already in tray two it was one of the first solutions we tried but to no avail. Thankfully the door mod worked as the vertical roller wasn't the cheapest from memory. If it gets 500k out of it before needing replaced we will have done OK

over here they are about $35 I carry 6 in the car. Use them every day now. :cool:

any 4 series or early e series with the solid black roller is changed now whether jamming or not.

Oh really? I'm near sure when I checked them they were £50-60 each. This is for the vertical feed your talking about isn't it and not the tray two pick up roller?

Correct.

Someone is making a killing on those rollers, cant cost more than $10 to make.

Well, this thread came in quite handing about a week and a half ago. I myself, didn't bother buying new springs or adding washers, etc. What I did was take all three springs off, shrink the hook loops down at both ends of each spring with my needle nose pliers. I then had to slightly trim the end of the hook in order to have an opening wide enough for them to be reinstalled. I put them back in, put everything back together, and no more jams.

I effectively shrank the spring, creating a higher tension when installed. Customer was getting multiple jams a day (20+), and has not had a single jam in the last week and a half. A free repair, no parts needed, just a bit of time...

hi, Isaac the new spring issue (j2002) came from Konica Minolta. we also received this modification. by the way, I checked your remedy. it's good and I might try it in the future. thanks for the info

Just thought I'd post an update. It's been over a year now since shrinking the springs on this particular machine, and still not a single J2002 since. I've done this to at least another 5 machines since, and they are all jam free as well.

While not the fastest method listed here, it is the cheapest. It costs nothing at all but a little bit of time.

Hi, do you think if I put a thickness of paper or tape, I could solve the problem? It is very similar to your description. I have a bizhub C364e with several 20-02. This happens especially with A3.

I think it needs thickness more than 1 paper. Try fold it 2 or 3 times

Just click the words, "Attachment 28327" in the post you quoted. It is a link, and clicking it should download the PDF attachment you are after. I just tried it and it worked for me.

[QUOTE = altech; 460267] No sucede todo el tiempo, pero cuando se atasca fuera de la bandeja 2, hace un sonido chirriante y arroja el código de atasco: 20-02. Reemplacé el ensamblaje de entrada de la bandeja 1 y la bandeja 2 por uno nuevo y todavía sucede. ¿Alguien ha tenido algún problema con este mismo problema o conoce una solución? [/ QUOTE]


I recommend you to see the wear of the clutch, verify the number of impressions made, and the modification of the spring.

Greetings and luck
