Sharp MX-6070n SKIPPING random pages

[Guest]

We have a very weird issue in our office that's been going on for about a month.

Randomly, usually in the afternoon, the scanner or copier will literally skip pages - as in, the pages don't show up in the final file. The pages will feed through the document feeder with no errors, but the pages won't show up in the final PDF. For example, there was an 81 page document scanned in and sent to a third party, but page 12 was randomly missing. When it was scanned again, page 12 showed up. In addition, sometimes when making copies, the copier will only copy a portion of the pages fed through the document feeder. There is no warning, error code, or other indication that this is happening - the only reason we caught it is through human eyes.

This problem has stumped our regular support people. There was even someone from Sharp out here to take a look at it this morning. He printed out some report page (that I still can't find the source of) that showed there were document feeder jams and errors. I've never recieved an error message or an alert that the document feeder has ever jammed. The techs insist that if there is a jam, then it will display a message... but there has never been a message.

I'm convinced something is seriously wrong with one of the components between the document feeder and whatever digitizes and stores the documents to be stored or copied. The problem is impossible to re-create on demand, which makes it difficult to document.

This seems like a wild glitch type thing to me, which wouldn't surprise me. What does surprise me is Sharp's inability to figure out what's going on. Any thoughts?

Try turning off blank page skip mode or push the black start button instead of the color one

Re: Sharp MX-6070n SKIPPING random pages

It is possible the doc feeder is double sheet feeding causing the skipped pages,also when the problem is random and can not be recreated repairs are usually a guess to what you think might cause that problem. So unless it recreates the problem for the service people it can be hard to solve without a lot of trial and error. To me it sounds like a doc feed problem.

I've had the same issue with a 3070 at a customer who does a lot of scanning of 20 or so page documents and would complain of missing pages. Couldn't ever duplicate it despite personality scanning hundreds of pages. We replaced rollers, clutches, and even the whole paper feed mechanism without resolving the issue. Finally had to convince them to buy a desktop scanner, so I'd be interested in a fix (or even a way to duplicate the issue) too.

Re: Sharp MX-6070n SKIPPING random pages

maybe you should check the count of the originals with the "original count" function to make sure all pages are feeding correctly...then you can scan and send them...otherwise, this problem sounds impossible... unless you are getting the correct amount of sheets but one of them is blank...I've seen a problem like that... but never where a page is scanned but not transmitted...

I assure you this is what is happening. Just today, a user scanned a 7 page document (the copier confirmed this), made 4 copies... and only 6 pages of each document came out of the finisher. The people at Sharp are very reluctant to admit there could be a problem with the machine, even though they've replaced some of the internal components. We checked our power, had the power company come out, even switched locations with another machine. Same issue, and it's completely random.

Believe me, I wish it were impossible! The reply on this thread about the 3070n is the only other instance I've seen on the whole internet of this happening. Whatever the problem is, it has completely destroyed our users' trust in the machine. Not good. I hope Sharp is able to resolve this as a replacement machine seems to be the only option left.

Sharp is pretty good about replacing things. My best advice for you is to scan / copy with job build while you get this problem sorted out so you aren't wasting your resources.

I am a Sharp tech in Illinois and hope I can help, here are two things to try. 1. Try using the original count feature on your copier to count your originals, it is under special functions. Also web into your machine by using the ip address and going into the browser and go into the copy function settings. See if quick scan from document feeder is turned on, if the box is checked then turn it off. Also check the box that says 600X600 scanning from document feeder. Both options will be under copy settings under the initial copy settings on the bottom of page. try that and hopefully it will help, on quick scan the document feeder has a tendency to skip pages. Let me know if that helps and I will research a little more on your issue with the other techs in my department.

the scanner or copier will literally skip pages. it means that scanning and copying is skipping pages? Correct me if I'm wrong, is it happening also in printing?

here is your problem, the spring under your set pad is too weak, order a new one and that will fix your problem. Just recently had the same problem just on Friday. replaced the part today and all is right as rain. cheap fix also. That should fix your issue

Re: Sharp MX-6070n SKIPPING random pages

MX-6070 does not have a separation pad, it has a separation roller. The spring requires a lot of disassembly, to tweak, to make stronger or weaker. I would have installed new rollers first in the machine and then ran 50 pages through 10 times, of clean paper. Should get 50 each time, then try the paper work you are having problems with. Freshly printed paper has static in them, like a sock to another piece of clothing. This static can cause paper to stick together and be missed when scanning.

I would first start with a stack of clean paper to see if its all forms of paper, or just the stack you are trying.
If it is all forms of paper, then maybe the setting is turned on to skip blank sheets of paper.

The roller, that paper rolls over, not under, is the separation roller, and its job is to hold back the second sheet, so only one sheet at a time goes through the feeder.
