FS-C8525MFP, massive voids with K

[Hansoon]

I barely know how to switch this machine on since I'm a KonicaMinolta guy. FS-C8525MFP has around 140K mono and 40K color on the clock. Suddenly this morning there where massive voids when using K, front to rear across the feeding direction. Color is more or less OK. When I was there now almost no image when using K, print is mostly complete without an image. The mag roller is complete without toner/developer. What can have happened? No developer unit drive? Broken gear, clutch failure? Does this machine is a 2-component developer +toner or toner only system?

more than likely its the developer unit but at 140 k for black there is a maint kit to be replaced at 200k. dual component for developer, I would replace drum and developer and if you are using generic toner, you are screwed. I would start at drum and developer[

first what have you done?
any scans of the problem?
sharp or fuzzy voids?

so many questions
so little information

- Done nothing except looking at the mag roller finding a clean roller without any traces of toner.
- Scan attached
- Voids are very fuzzy.

Thanks

It's the developer unit K. Replace it.

OK, will do, thanks. Does it require a special set up?

Still wondering why - within a few prints - it completely fails. My experience with other brands is that prints gradually deteriorate before its fails finally.

There are destructions in the box. It will do the developer stir by itself as long as you power off before doing the swap. The color calibration is pretty basic on this model. =^..^=

Re: FS-C8525MFP, massive voids with K

From memory these little beasts have a K dev drive clutch on the back of the main gearbox, 302K094320 - PARTS CLUTCH 50 Z45L SP

We had lots of them go on the 8020 - 8025's

Very easy to get to with a small clipped cover over it.

Could be the problem.

Re: FS-C8525MFP, massive voids with K

Thanks, besides that the developing unit will be over the end of its life ofcourse, I could very well imagine that the clutch has a failure based on the effect on the prints coming out .

Any of you guys having the parts manual for me please? The tech manual I have already.

Parts clutch 50

Re: FS-C8525MFP, massive voids with K

OK, went there, clutch was working but to be sure I opened the flimsy toyish part to give it a good clean and inspect it further. Still no K image so I have to bite the bullit and get a new developer unit.
BTW, developing units are mechanically coded, so no way using a color unit in place of the K unit for testing.

Re: FS-C8525MFP, massive voids with K

As mentioned before, clutch is working OK. Replaced the Developing Unit K with a new one and machine is up and working again.

Thanks for your help guys!

Customer came up now with another issues with this machine:

It takes an annoying long time to wake up from energy saving/sleep mode when sending a print to it. Where can I adjust this? No need for any kind of energy saving or sleep mode here.

Another thing is that the user wants to scan from the platen (not ADF) more than one document to be put together as one PDF. The KonicaMinolta's I am familiar with can do this. Can the Kyocera too? Where to find the settings please?

Re: FS-C8525MFP, massive voids with K

The scan function that you seek is called "Continuous Scan". It allows you to group stacks of scanned originals into a single PDF. That includes scans from the copyboard glass.

I've attached the pages about Energy Saver Mode. Keep in mind that there are serious drawbacks to lengthening out the sleep timer. These fusers are not the greatest, and definitely will not make yield if it's always hot. To get the longest life you'll want that sleep timer at 3 minutes or less.

This information came from the operators guide. =^..^=

LOL, thanks Cat

This customer is a little tricky. Always looking over my shoulder when I'm there and I do not want to look too inchoate not only searching the menu of the machine but also skimming the manual for info.........
