MX-FN9 Stapling Issue

[Tech2002]

Got an issue that I have not been about to figure out.

While stapling multiple pages last page does not jog into place to be stapled. Pulled top off Stapling Unit - carried out the Mod MFP-TP-698 - cleaned all feed rollers, blew out any debris - everything seemed good - then started up again, doing the same thing.

Any suggestions to try?

Thanks.

Re: MX-FN9 Stapling Issue

Most problems i had with stapling on the fn9 were caused by the 2 belts Fig 4 (transp section 3) item 8 .

They were not pulling the paper back enough.

Appreciate the reply - It threw me that the last page was the only page/copy that did not align for stapling. I'd do somthing - like make the Mod Change and things would be okay - for awhile. When it happened this last time, I though it might be a timing issue, to a board issue. Tech Support didn't have an answer.

I'm guessing that you changed the two belts and that was the fix? Looks like a big job - time intensive repair.

Again - appreciate the heads up.

Actually, the belts are easy to replace...

Haven't had the opportunity to have issue with this Finisher. They have run good with maybe a few squeaking issues. I just looked at the PG and not the system itself to see what was up with belt repair/replacement. But then, the PG isn't the same as looking at the system or doing the repair itself, is it?

Thanks again for the info.

Refer to the mxfnx9 service manual "disassembly and assembly section 6-4" instead of the PG.

Only had access to PG at the moment. Thanks.

Re: MX-FN9 Stapling Issue

Someone else who has dealt with this issue asked me to pass this along. May help with your issue.

The usual fix for this is a tight belt up/down shaft. The belt up/down lever (parts guide section 3, item 27) rubs against the frame preventing smooth movement. The bushings at each end of the belt up/down shaft with the lever drives also need some lubricant in them.
Basically, the compiling belts do not lower down onto the paper enough to pull the set or individual pages back into the compiling brackets before stapling. The belts need to lower all the way down to correctly contact the paper, and a tight belt up/down lever and/or shaft will prevent the compiling belts from fully lowering, thus pulling paper back into the compiler brackets with low torque/pull.

Thanks for the info - Not always able to get the fix on repairs - some of it is because the need never arose to do a fix or there isn't anything you're able to read that can help. I don't have the Tech Bulletin but there is something a buddy of mine sent me via fax - Haven't got it to add here - but if it is something anyone wants I'll get and post it - Thanks again.

There was a suggestion of changing the belts. With your suggestion of lubicating the shafts would you still change out the belts? They appear to be good. I guess my question is, when you lubed those areas, was that all you needed to do to get things back to standard?

I've not done this fix personally, but it was relayed to me by a very reliable source. I would think if they still appear to be good you don't need to replace them, but if your problems continue after taking care of the rest of it, I have confidence you would know what to do at that point.

Re: MX-FN9 Stapling Issue

I would clean the shafts first and the re-lubricate. If the belts look good I wouldn't lean towards changing them just yet.
