Belt cleaning unit
Hi,
We tried swapping the belt assay and belt cleaning unit between the two machines. The dirty print fault stayed with the same machine (Printer #2).
This is so very strange. I'm sure it's starring me in the eye. I'm just not seeing it.
I did also pull both belt cleaning units apart and totally removed all the toner (they were very full in the worm drive). But this made no difference also.
I think there is an answer to this puzzle though. When the duplexor is added, the dirty print is on the front bottom of the page. With no duplexor it's on the top back of the page. So the paper travels in a different path causing the leading edge to change I guess? Maybe this doesn't help? I dunno. Another late night working on it in a sec. lol.
And the creasing of the paper with Printer #1, changing the fuser over does not change this. So can't be the fuser. More mysteries.
I do wonder about the plastic path ribs on the back of the printer and the top cover with output rollers. Is it possible it's creasing there some how?
I will try and swap these across also tonight.
Original owner of Printer #2 is now trying to say he had Magenta dev unit replaced. But the paperwork does not say this.
Oh one last interesting thing.
With Printer #1, when printing a full page gloss print, like a photo etc, it never creases. It is more likely to crease when there is just minimal text printed on the page. Very strange.

Yes, you can try to check all the "ribs"/guides that direct the paper. A small notch can catch the leading edge of the paper and cause it to bunch up.
Cleaning unit thing, is a mystery I guess.
The duplex unit on/off happens because the back side is printed first during duplex.

Ribbing....I can't recall anymore if it was the 5016 or the 3800 (B/W) but I did once find that the paper was exiting the fuser and one corner was just OFF the ribbing. It rubbed on the side of the rib and created a deep scratch which in turn started to grasp the paper and cause creasing.
I added some thickness to the rib by cutting out some clear plastic (2mm thick) and gluing it on the side face of the rib.
Hope that makes a bit of sense. It's been more than two years since I last worked on a Kyocera...

Can FS-c5025N be used For parts?
Hi guys! Still at it.
The main FS-c5016N is printing ok for now but it does have a faint stripe (lack of megenta we think) across but offset from the center of the page.
We think this will just be a simple drum swap from the other unit when we get time.
There is also a squeak in the unit now when running. But this could be the un even surface flexing the unit. (Table is bowed a bit).
Now our next big question.
We have found a FS-c5025n with duplexor and second draw.
Are the internals compatable for parts with the FS-c5016n to any degree?
The fs-c5025n has a black stripe throught the print aparently.

aiaiai. you deserve an applaud for stamina, thats for sure.
faint stripe can be drum, dev, 'brain' or leds. unfortunately my guess is dev. run colour calibration from meny first anyways.
squeaking is prob. exit rollers/shafts as they are plastic in plastic.
partnumbers on internals in 5016 and 5025 are different, so bookwise nothing will be interchangable. seeing as they have different toner, and the fact that the 5025 actually works, i guess it's true in real life too. spend your time on the 5025, dump the 5016

Re: FS-C5016n black toner hanging like spiners web from paper?
Hi Guys.
Still playing with these FS-c5016N's.
I think we have about 4 units now (3 for parts).
The one we use has developed a new problem.
When printing as specially when it has sat off for a while all the black toner doesn't stick to the paper.
The prints come out with the black hanging everywhere from the paper like spiders webs.
Any idea what this could be?
