[Jamming] Another AR-M351U Jamming AINPDS

[vlad_robas]

Hello,

The macine has about 730K which we got from a customer, we replaced the maintenance kit, drum and rest.
All that is left to resolve is the jamming that he is doing at duplex. I have read all the other 4 post's that i could find on this subject but this is not the case becouse i mounted a new AR-DU4 unit on the machine and the jam is happening in the same location, i have replaced the reverse gate and unit from a working machine and the problem is the same. The jam is afther the first set of roller's in the duplex right on top of sensor and is repeating very ofthen (almoust at second or third page) Is happening from both tray's. Somethis during the replacing process and the test paper wasn't passing much afther the gate but in most cases is stops where i said earlyer.

I have no more ideea's, I look forward for your's.


I have listed a sim 23-80 but i don't know what to look for since the other machine that i have is AR-M451 (different speed).

hi
do you try take a copy for a left output ?
perhaps the copies come with delay, and the
issue was in the copier.

good look

The second set of rollers on the turn around unit (Rollers are driven by the stepper motor) that push the paper out the right side of the machine and then back in for duplex or left had exit have given me problems before. The grease on the idle roller shafts gets dried up and the idler rollers don't turn easily. With 730k i'd replace that turn over unit or rip it apart and clean all the shafts for the idle rollers. The idle rollers right above the fuser also have that problem.

I did replace that steper motor and then the whole unit from another machine and it jam the same way.

hi vlad
today I had a similar problem, i was gewtting a adu code jams, and the issue
was in the FN6.more precisely at the exit of the printer, for fn6.

took the fn6 out, and clean the printer rollers( as lawrence said), gave a litle pressure
in the four springs above the four black rollers put again the fn6 and know works
good.

It sounds to me like a sensor problem. The fact that the jam occurs in the same place but not every time. Sharp's photo sensors will go intermitent sometimes before they completely fail. I also had one machine that had a burr on the plastic guide in the FN6 turn around section that caused jams only when duplexing. The guides are thin plastic and easy for someone to damage while digging around.

Those delivery/turnover units are notoriously unreliable. I would not trust a used unit regardless of the source. I've documented at least two brand new, in-the-box delivery/turnover units that did not work.

Before you start looking for exotic causes, start with the common one. Install a new delivery/turnover unit. =^..^=

I think we solved the problem afther adding another twist on POD3 spring. Funny thing is as i also sayid that we replaced the whole unit from another working machine and the problem was the same. And we also cleaned Fusing back roller.
We will wait and see if this is the final solving of this problem. Thank you all for ur support.

how about the ps clutch?

Re: Another AR-M351U Jamming AINPDS

The old AINPD sensor issue sucks. I have had 2 machines do the same thing and the best fix I have found is to put a little oil on the pivit points on the sensor arm and also file or sand the arm, it has small cuts in it because of the paper hitting it over and over in the same spot. Any duplex or left exit copies always trips that sensor.

Did the extra rap in the POD3 spring work? Please keep us posted because I have a machine still having issues with AINPD_S jamming
