Xerox 4110 streaks on 2nd side

[paul_gmb]

Hey There,

We have a 4110, that we run inside the company, and we often get streaking lines on the 2nd side, even if we print 1 sided.

Sometimes it's harder, sometimes it's thiner, but we can't find a pattern between the lines. They go all the way from the edge to the tail of the paper.

Only time we get on both sides, is when we print 2 sided.

We replaced the following :

1. Transfer belt + cleaning belt
2. Drum
3. Pressure roller
4. Made a thorough clean of the machine and developer housing.

Anyone had such issues ?

Regards,
Paul

It would be best if you post a pic. Depending upon the problem, the defect could look may different ways.

Fa un document A4 cu o singura linie in diagonala. Apoi da la tiparit , o singura fata, acest document in mai multe exemplare si opreste masina in timp ce tipareste. O sa ai 4-5 foi blocate pe traseu. Acum ia si examineaza foile de hirtie pe fata netiparita si vezi la care apar dungile. De obicei aceste dungi pe fata netiparita apar de la ghidaje sau role murdare. Rolele de registratie pot fi o cauza dar tot traseul hirtiei trebuie controlat.

Re: Xerox 4110 streaks on 2nd side

If the streaks are pretty constant on the back side of copies, the easiest way to determine what area of the machine to blame is to do a hard stop test.
Open the front door and use a wad of paper to trigger the door switch (please do not stick your fingers in any mechanical or electrical areas with the door switch jumped. This negates the safety feature). You will also have to jump the sensor for the small toner door that is part of the front door (a small piece of paper wedged into the black sensor will trick it to thinking its closed).

Run 1 page at a time.

You may need to do this a few times to get the timing down.

As the copy is being made, pull the paper out of the main door switch to trigger a paper jam.

Jam the paper over and over in various stages of the copy being made.

Check the jammed paper for the streaks.

You will be able to determine at what stage of the copy the streaks are being created to better pinpoint what component is to blame.

In my experience with 4110, its usually the fusing unit causing the problem. Does your 4110 have the double cleaning blade under the pressure roller? I often see this cleaning blade removed. It's job is to keep the pressure roller clean. Is the cleaning unit (fusing web) in good condition and is the web roll wet? If the web roll is dry, it will not be doing a good job keeping the fuser clean. I've seen poor cleaning of the transfer belt cause streaks on the back of pages too but you would see a dirty streak on the belt itself when you pull out the drawer.

Xerox has gone through a bunch of different toner formulas over the years. Most of the early versions of OEM toner would cause the fuser to get too dirty and give streaking on the back side. If using this toner it is very important to have the pressure cleaning blade installed and in good condition.

Hey there,

I've attached a photo of the issue :

IMG_20150305_121637.jpg

It's ussually on the edges of the paper. The reason why you see this on the printed side, is that it was printed duplex.

1. Fuser web was replaced 5000 prints ago
2. Pressure roller was replaced
3. Fuser blade is missing, but I will double check
4. Toner bought from Xerox distribution channel ( most of the boxes have closer dates )
5. Registration path and rolls have to be checked
6. Pressure roller replaced ~5000 prints ago
7. Drum 10000 ago, had the problem before replacing

Thanks for all your help !

PS: Am discutat azi cu cineva de la Xerox, si modificam si lucruri prin NVM, dar trebuie vazut si cu rolele de registratie.

Nu cred ca este cazul sa umblati la nvm pina cind nu se stabileste ca dungile apar in zona de transfer sau in zona de cuptor. Se poate sa inrautatiti situatia.

Re: Xerox 4110 streaks on 2nd side

So, a little update:

1. Machine had also fuser roll replaced and also developer - nothing changed
2. Presure between fuser rolls 12.1 mm average pressure pattern ( ~highest pressure according to service manual ) - lines have faded, but still there .

What we have found is that lines do come from the fusing area, and for example if you print a 2sided a3 with text, lines will come up on the 2nd side exactly in line with the 1st side text. It's sort of as the fuser roll is not getting cleaned, or worse, it transfers to the pressure roller.

We checked fuser web, and it is very very dirty. It is indexing, but compared to the other machines we have, it seems too dirty. The fuser web was replaced not that long ago.

1. Temperatures in NVM have been se according to the Xerographic baseline Xerox released in 2011 I think. I didn't seem to recall a newer one. There it said the replaced values for long life fuser web, but the indexing speed I could not find.

2. Are there any cleaning blades for the fuser. We searched and searched and couldn't find any cleaning blade on the fuser. In the Eureka tech we found a post that was mentioning something about a blade, but we didn't find the part number ( we suspect it's for another machine ) in the service manual.

Unless there is a spar update, the pressure roll has a cleaning blade that can get toner buildup and cause this problem.

100% there is no pressure roller blade. For what reason don't ask me. Should it have one?

Can you please tell me the part number? So I can check it?

Re: Xerox 4110 streaks on 2nd side

There is no blade for pressure roller on the XE machine.
What is the pn of the new pressure roll you replaced ?
Sometimes 59K69790 build electrostatic on it.
You may try 59K37001

59K37001 Installed

In the service manual found no blade, that's why I wanted to know the pn.

This gave me an ideea. If it's statics it has to be a conductive "brush" to dissipate it. I will check on monday that. It could be either dirty or damaged.

Hey there,

So, found there is a pressure cleaning blade ( someting like a wick ) being a part no in the 4112 machine.

Anyone exprienced with the so called "Medicine toner" ?

Re: Xerox 4110 streaks on 2nd side

Hello, i have a xerox 4112. I am having the same streaking problem. But streaks are in the longer direction of the page.

I have changed the Drum. Cleaned the developer housing and changed the developer. The fuser cleaning web is fine. But these lines do come up in between the prints randomly. Like in between 500 prints and sometimes after 1200 prints. And if anyone have a service manual for 4112, then please send me that also.
Thanks
