Aficio 2060 Strange Jamming on duplex.

[nobody-here]

Dear Friends,

I have a Ricoh 2060 that has a strange problem.
It works great, but if I Duplex is activated, paper jams inside "aligning rollers" of 1st paper tray.

Othe infos
- Duplex works on 2nd and third trays.
- Single side works great for all paper trays.
- History SC Log indicate error "12".
- All rubbers are ok, frictions are ok.

Any clue?
What are differences between "duplex/noduplex" in paper path?

Thanks in advance for any piece of information!

Readjust the paper guides on the right side of the 1st feed tray. Because of all of the weight when the customers SLAM the drawer, the rear guide gets pushed back a bit, and there is too much slop causing it to jam in the duplex unit.

Grab the rear guide and pull it forward to where the paper sits much tighter in the lift tray and doesn't move back and forth.

If something else is going on after this adjustment, please give additional details. This will fix duplex jams out of drawer one once it hits the duplex. After I read your post again, I'm beginning to think you're having a different problem, where the paper is still stuck at the first feed station, but I'm not 100% certain exactly where the paper is stopping.

If the tandem tray side fences are not the problem, then you may have possible feed unit contamination by developer material, or the one way bearings may be shot or need cleaning/lube. The timing is more critical when duplexing so these problems occur more frequently.

Thanks a lot for your kind help,

well, guides where the first things that we checked. They're ok, fixed and locked.

I am trying to be helped from a collegue, He tells me that the paper stucks in "registration roller". Paper don't reach duplex module. It stops always the same way.
I will enclose a picture showing where paper locks. SC log indicate error 12 that seems to be related to "restart sensor".

Thanks again for help.

There are specific fixes for jam code 12. They all relate to problems with the feed units. I have seen this problem occur on numerous occasions. Chances are you will be tearing into them.

Ok, that's makes more sense. I will assume that you've already swapped the feed stations to make sure that feed station two feeds fine out of one. I will also assume that both the relay and registration sensors are thoroughly cleaned. Just because the other drawers feed fine doesn't mean they are not contaminated. Weird things do happen sometimes.

Jam 12 is that relay sensor accessed from the two-screw cover.

I agree! I've refurbed feed stations on 6 machines with similar problems this year.

First remove the dev unit and look for signs of developer (Not toner) inside the machine (Front and Rear) and around the base of the WTB. if you find any the FIRST thing to do is replace the bushes at both ends of the dev unit.

Check the gears at the rear of the feed station for wear / dev contamination, change the gears as a set. Remove the feed station motor from tray 1 and look for dev in the end opposite the drive pulley. If you find any change the motor (not expensive).

Remove the registration unit and look for dev near the reg roller drive gears. If you find any change the one way bearings on the reg unit. Check the reg unit guides and change if the mylars are worn.

Generally speaking, shortcuts don't work with this problem.

first of all, thanks.

I will try all of your helps. I'll let you know.

Solved

Ok, everything is ok, problem solved.

After a big cleaning, we also found a little broken gear in the paper feed that was involved in timings. Changed it, and worked.

Thanks for all advices and help.

Bye
