Aficio MP C2500 (Athena) w/ SR3010 Finisher - Jamming

[SGT_Snacks-64]

Hi,

Had this call just now, got home from it but couldn't resolve it today. Returning tomorrow morning to hopefully get it fixed. I was wondering if I could get some input as to what the problem may be.

Basically, this jamming problem only occurs on Staple jobs of more than one set. The first set comes out perfectly and staples fine, no problem. The second set will print too, the last paper in the set comes to the finisher, sits with the other pages as if it were about to staple and suddenly a Jam occurs. This always happens on the second set, no matter how many pages there are per set. The paper doesn't appear to be getting caught anywhere in the machine.... just stops.

I've checked the sensors in the finisher and flushed them out, plus I've checked the actuators for sensors to ensure they're in the right position. There is a fresh ream of paper in the paper tray "This is coming from Tray 1".

I'm kinda ripping my hair out as to what the problem could be, I just know it's going to be something dead simple!

This machine's been running since last October, has done about 250k prints in total "Colour and Black, copying and printing".

Any help would be greatly appreciated =)

Thanks,

Hi Mike
This sounds like a firmware issue but I dont see any updates for it.
I would try the main finisher PCB.
Good luck

I'm also dealing with a 'guaranteed-to-jam' situation with another Ricoh line and I've done enough known-good component swaps to lean towards firmware as well.

I was just waiting to get the firmware files, which I now have.

Update the firmware first and wee what happens. I was just swapping components to see if would make a difference, but I didn't think it would. And, it didn't make a difference.

Of course it COULD be a flaky board, but you'd think that a board going bad would exhibit other problems as well.

Check the code in sp7507

I checked the code, it's jam log 164 - Stapler doo dar area. I went back to the machine today and had no luck, so I've ordered a staple unit and a board just to be on the safe side. Unfortuantly I'm away next week so someone else is fitting it I'll let you all know what happens.


Thanks,

Lets see, you say "stapler doo dar" and my book says "staple cancel"
I dont know what the hell either means. But I would say the stapler and main board are good bets. I can tell you aren't unhappy about not being able to complete the troubleshooting

;D I stopped worrying too much about not being able to troubleshoot a problem a while ago, it's a Photocopier, not a life support machine ... that's how my manager used to put it when I had panic attacks over the phone.

This may seem daft but.....

Did you check the belt that drives the sponge positioning roller? On some finishers they have a tendency to emigrate to the bottom of the machine.

I've had this tons o times on the SR840/841 finishers on the Martini, Bellini and Katana.

Not daft at all,

I checked all the drive for the finisher, the paper entrance and the paper exit "after it had been stapled" and unfortunatly no luck.

FYI, this is the finisher in question

Haha, more fool me.

For some reason I had the SR790 in my head

Are the joggers moving ?

[SGT_Snacks-64]

Are the joggers moving ?

Yes, everything's moving correctly and mechanically the finisher is fine.

Another Engineer went in the other day, who couldn't solve it either. The call's been escalated If I find any info I'll post it here.

[FRIDGEMAGNET]

Right - Guess time.
I have not seen one of these finishers but I just read the manual.
The fault occurs when the 1st set is exited and the next set is ready to exit (last sheet fed to the stack).
I think that the stack motor is faulty and not lowering the stack correctly.
On this model, if you get a motor error, the machine firstly shows "finisher jam", and then if the same error occurs then it shows "finisher error".

I've had one of these smeggers do this. Does it throw up this jam on power up and then when you open the lid to clear it, it throws up SC792 or something similar?

To cure I replaced finisher main board, the two stack height position sensors and a sensor buried in the black thing that holds the wiring in on the non-drive side of the finisher.

Apologies for the massively untechnical descriptions but I'm not with my laptop at the moment! If you do need more details let me know, I'll get the part numbers and page numbers etc.

[SGT_Snacks-64]

Right, apologies for being quiet on this one, have been away on a course for the past two weeks. Got the e-mail back from the Tech who attended the machine the other day, and here's the verdict, this one's good...

The Harness for the Staple unit "Which moves right across the Finisher, does Double as well as single stapling" wasn't quite installed correctly in the factory, this was causing the Harness to be overstretched when the Staple unit was doing single stapling "Corner Stapling" Thus shorting out and causing the Stapler Cancel. The Harness is in a plastic tube so you'd have to cut this open to check the Harness, Tech installed a new Harness and hey-presto! I'll grab some Manual snaps of the section when I'm more awake "Damn training course"

Thanks for everyone's input, this fault is now cured.
