Ricoh MP5500 duplex jams at B2 gate

Re: Ricoh MP5500 duplex jams at B2 gate

Went back today and tried swapping feed units, no help. Did not try updating firmware but probably will try as I have nothing to lose. Thanks for all the input. If I figure it out I will let you know what it was.

Re: Ricoh MP5500 duplex jams at B2 gate

I just found my notes, they are 7-504-13 jams.

I'm willing to bet that it's paper dust on the registration sensor. Take the dev unit out, remove the 2 screws on the plate underneath it (the top of the registration) and there's a sensor there which is prone to being covered in paper dust.

Also check the black mylar guides in the registration as these get marked with a white line and eventually tear over time.

I see that Vargue is being as objectionable and wrong as ever!

Re: Ricoh MP5500 duplex jams at B2 gate

Just to check, the machine does not jam on single sided from the ADF, so invertion is ok?

Have you inspected the duplex unit plugs / sockets VERY carefully? I have had VERY small bits of paper in the sockets cause strange problems, if there is toner on the paper it's very difficult to see. You need to get a "pointy thing" and scrape the inside of the socket.

The older versions with 2 duplex transport clutches used to have similar problems when the clutches slipped, may be worth swapping the duplex unit for test if possible.

I agree that the reg sensor could case the issue, also the relay sensor (the one before registration).

The vertical transport relay drive can cause odd faults. check the motor and one way bearing. Is there any noise as the fault occurs (Stepper motor?)

Does the fault happen feeding from all trays?

Good luck!

Re: Ricoh MP5500 duplex jams at B2 gate

Thanks for responding. I did try a whole different duplex unit, inversion unit and registration section unit. On each i cleaned all the sensors and guiide plates. Single sided copying has no problem at all. Also, you can run one or two duplex copies no problem but when you try multiple , 3-5 plus , is when it jams. Always at reg rollers. It seems that reg rollers dont turn on quick enough and then paper bacs up and gate b2 pops open.
I did look behind duplex unit with a flashlighta at the plug but did not see any paper stucK. All drawers jam on duplex, simplex runs good.

format the hdd......if it runs well , then change hdd.....

just!!!!!!!!!!! try yo don't lose nothing replace registration clutch.

Re: Ricoh MP5500 duplex jams at B2 gate

Have seen similar. It's something to do with the interleave timing between paper feed and duplex so must involve paper feed drive / relay / reg timing (sensors) / one way bearings dragging (feed station). But, as you changed the reg unit, the reg / relay sensors should be ok.

Dev spill? will effect pf stations.

Did you did say you had swapped the tray 1 paper feed station? the only one common to all feed. Swap with tray 3, should be the best one

I'm probably repeating a lot of what has been said, but it's a train of thought!

Is there any sign of registration shift?

Paper feed control board?

Does paper size make a difference?

Check the drive belt condition / tension at the reg MOTOR drive (Vargue!) If someone had the unit out and forgot to reset the tension it may cause timing problems? (But, you HAVE changed the complete unit!)

Also the small motor control PCB (DRB ptop A/5 1 of 3) UK part no D0545185 (Timings different in US?) modified to "Improve reliablity!".... controls the Reg / Relay / Duplex and Duplex transport motors (!)


As I mentioned the Duplex sockets, also the FUSER sockets? could interfere with the precise timing for duplex?

There

Is

NO CLUTCH

Is this really such a difficult concept to grasp? It's a motor, not a clutch. Christ...

Anyway, you don't have any dev floating around on the registration or tray 1 feed, do you? If the dev unit leaks then it contaminates the feed units, from the top downwards obviously, and the registration. Also, did you check those mylars in the registration?

As a side note, these machines use the duplex unit for single-sided copying too, although not the right-hand side of it.

Finally, can you double-check the jam code that you're getting?

Re: Ricoh MP5500 duplex jams at B2 gate

Casting my mind back, I had a similar problem to this on an MP8001, namely jamming on duplex only. From memory, which isn't very good I must confess, I changed the transport motor in the duplex unit which fixed the fault, however the new motor failed shortly afterwards.

It turned out to be a damaged wire in one of the looms, I think, but this was some 2 years ago.

The jam code, assuming that it's J013 as you said, is the paper failing to reach the registration sensor (under the dev unit as I mentioned earlier) on time. I'd have the whole registration out if I were you, check it for dev floating around in there, and finally make sure that the registration MOTOR (that's motor, Vargue, not a clutch) is turning freely. If it feels at all stiff, replace it. I'd also check that the feed motors are free as well. Come to think of it, the feed rollers are ok, aren't they?

And check those mylars/guides in the registration!

he's changed the reg unit / duplex unit and inverter complete. starting to sound like either a "What did the last tech do?" or Board failure / loom.

Could be the reg clutch!? (Who is looking at the AF2075 manual then!???)

The 2075 had a motor too

If the machine runs forever on single-sided without jamming yet jams almost immediately on duplex then it has to be an issue with the duplex unit transporting the paper back into the machine for the second side or the machine thinks that there's a problem. I'd be inspecting the duplex connector on the rear of the machine very closely for a bent pin or tiny piece of paper. I'd also have the whole thing to bits again, just in case I'd missed something the first time around.

This is getting to a point where, without being in front of the machine, it's very difficult to diagnose a fault. Cheat the front door and run the machine with the front panel of the duplex unit off to see whether anything seems to be stalling, perhaps?

Or, dare I say it, damp paper?

Sorry, wasn't popping at you.... and I had RTFM mode switched off!! Agree about the socket, seems like a mis-timing as the duplex sheets feed between the 1st side sheets (Used to love watching that video!) and as all the motors are controlled by the DRB.... got to be worth a punt if a donor m/c is available.

Re: Ricoh MP5500 duplex jams at B2 gate

thanks for all the replies, ideas, thoughts, etc. I took a day off(needed it because of that machine)! I agree with the timing issue of mixing duplexed copies with the first side of the page. I will be going back on Monday and take a hard look at the connectors in the back of the machine. I've really replaced all of the above mentioned parts/sections from a working machine, checked and rechecked all mentioned. Also bringing a second set of eyes with me on Monday-two heads are better than one. I hope it's not something totally stupid. Will let you know if we fix it. a good weekend to all!! maybe some beer or wine involved??!!

Did you replace the DRB pcb?
