paper jam entering devoloper section

Product Name: Workcentre 7556
Operating System: Apple iOS

Hi,

I have a Workcentre 7556 with finisher.  I am having issues with usage.

Upon start up machine goes through its paces and warms up.  As part of this warm up it sends a practice sheet which is two sided.  It successfully completes this process and when finished with warm up sits idle waiting for instructions from operator.

My issue is that it will not copy after this process.  It jams on input.  Paper feeds just fine, but stops inside left upper door before entering the developer unit.

Please advise.  xerox_paper_jam.jpgpaper jam

Hi,

Take out and check the fuser module and if is broken replace it. Eventually see what fault code is displayed in Fault History.

Grabrene!

Thank you for responding.  The fuser module is new and has been replaced.  That is the unit that has two yellow knobs that hand screw out and has to easy to hang on handles, correct?

I have had that thing out various times and cannot seem to figure why paper is not continuing on.

Will double check. I took it out again and do not see any restrictions.

No fault codes appear. Should I order another fuser?

Please advise.

Re: paper jam entering devoloper section

As mentioned, I don't see anything broken on fuser unit.  I have posted pic, the paper does not even enter the fuser unit.

Am checking fault codes.  Not sure how to do that, but have seen it done.  Machine just gives error message stating paper jam and shows area that I have in picture.

Fault codes in descending order from most recent.

392.678.00

392.673.00

389.626.00

389.617.00

Are these numbers what you are looking for?

No current faults.

The fault messages section says, out of paper, low on magenta . . . etc.  Nothing about any parts malfunctioning.

Thank you for your time.

Re: paper jam entering devoloper section

Hi,

The fault codes provided by you are not a paper jam fault codes, they are from MOB Sensor that not read properly the color registration (it is possible to be dirty). But for your paper jams are some parts that can be defctive: takeaway clutch, registration clutch, main motor. So is better to have a tech to diagnose your machine.

Re: paper jam entering devoloper section

Just by the location of the paper getting jammed, I would think the rollers might need to be changed. Just take the Fuser out and see if you can touch the rollers. If the rollers are really smooth, its time to get them changed.

At the same time even if the fuser is new, just check the bottom to make sure there isn't something blocking the feed.

Re: paper jam entering devoloper section

I can take the fuser out.  The model has two hand tight fasteners of both sides.  Also has two rectangular hooks hanging for a person to grab on securely and pull out after unscrewing threaded fasteners.  I have had out several times looking for and errant paper jammed in that section.  Never seen any, any where.  I don't thing the paper is entering that section due to the nicely wrinkled paper that is stopping the machine each time in the same way.

I have suspected this section, but unsure of what I am looking at when dismounted.  

I do observe the black roller and it seems that is does look smooth and glossy.  On both ends, one inch from the end, it looks very glossy.  That section extends at least one to two inches inward toward the middle.  Needless to say, that looks like the most neglected part of that roller.  The other roller is cover in an orange plastic cover of some kind.

I was gonna pick up this unit last week, but passed on it due to the inability of me to diagnose exactly why the paper jams previous to coming in to this section each and every time.

What is strange to me is that on warm up, the machine goes through its paces and sends and two sided text sheet out and that sheets prints just fine.

I have re-ordered this fuser unit and will attain first thing Monday.  I am anxious to see if this will help me.  I have inundated with copy work and cannot output this very computer because that was the only unit I have currently.

Thank you so very much for reviewing my situation and also taking the time to respond.

Re: paper jam entering devoloper section

Have installed new fuser unit.  Now it seems the same with a few less wrinkles in jammed paper.

The machine still puts out a great two sided test sheet in color on one side upon start up completion.  I don't understand why it won't work in normal copy operation after that.  paper comes from the same paper tray, the #3.

I have taken pic of companion to fuser unit which swings out when door is open to remove jam.  This unit works with fuser in feeding paper into feeder I am guessing.  It looks like this roller is a little discolored and has shiny surface on parts, but still seems to have rubber gripping power.

Please advise and thank you so much for your input.  Very important re-inforcement of my thought process.
