Kyocera FS-C8520 transfer belt cleaner problem

[rapo_tech]

Hello

Replaced 30k pages ago maintenance kit A.
Cause the belt cleaner was jammed and black drum was defected.
Updated firmware with full update.
Firmware ver. is 2MY_2F00.011.006 2017.02.16 is there a newer one?

And offcourse only OEM toners in machine.

Now the belt cleaner is clogged again and the gear on cleaner spiral was turned over.
I dissassembled the cleaner and glued the gear on spiral, but after 3 weeks when I went back to check the gear it was turned over again.
I checked the canal from belt cleaner to waste toner box it was clear.

Common problem with Kyo but is there any Bulletin or fix to this problem?

So the cleaner is backed up again. Check the spout and auger system moving the toner through the spout. It's very common to split a gear or two in the spout drive.

Yes thank you. Tried forum search but somehow did not find this thread...

I will try to drill holes as your picture refers
Front cover removal looks like lot of work...

So... costumer called that printer is making funny sounds and does not turn on.

Common problem with the power board - those two big capacitors (270uF 400V) were fried.


This time I brought my drill with me and drilled holes for the waste auger system

Turned out that there was a gear not engaging - shown on picture.

Glued it with superglue and lets see if that works

Hope this ends the drama with waste toner cleaning system.

There is a bulletin for this replace the toner pipe and the transfer belt at the same time

I've had good success with drilling a #37 hole through the gear and shaft, all the way through. Cut a length of large paper clip 3mm less than the diameter of the gear, and clean up the ends of the pin. Dip the pin in two-part epoxy, and insert it into the drilled hole, through the gear and shaft, centered. Clean any excess epoxy from the gear teeth (at the pin ends) with alcohol. I have never had one of these repairs fail.

Ok, good idea

But i already glued it with superglue... If the waste auger will not get clogged, i think the superglue will hold on.

Re: Kyocera FS-C8520 transfer belt cleaner problem

I wish you luck ... but delrin gears with "D" shaped bores tend to stretch, and a rigid bond like superglue will probably crack rather than hold. I do hope it works for you. =^..^=

Any good idea to fix the plastic clip back on belt? It holds the cleaning assy.

Btw I had a spare used belt, but when I was getting ready to install the belt, the lift handle broke and belt shattered on the floor FML...

I wonder if anyone has tried to install a 10k resistor across the big cap(s) to ensure that they can't build up such a charge, and so they drain when powered off?

If you have 1mm of space underneath the corner of the belt assy, you could cut a piece of 1mm thick black plastic to layer under the two parts, clean all of the surfaces with alcohol, attach with two part epoxy, then shape the resulting edges. Please excuse the poor quality of the illustration:

Yep I was thinking something similar.. I hope collegues find a used belt, so i dont have to mess with the epoxy

Re: Kyocera FS-C8520 transfer belt cleaner problem

With a sufficiently high value of resistor, the dissipation as heat will be low enough to be safe, yet high enough to dissipate the stored energy within a reasonable amount of time after powered-off. It is a normal feature of just about all mains voltage power devices such as wall warts, appliances, light bulbs, etc to have a high value resistor across the high voltage caps.

It would hopefully also be enough to clamp the crazy high voltages that seem to find their way into the caps when the power is noisy. That is admittedly happening inside some of the power supplies of the FS-C 85xx and TA-255-like device lines, per the bulletin.

hello I have in my stock the MK 895B I know for the Kyocera FS C8520 MFP I need the MK 896B but there is not available now can I use the developer unit from the MK 895B to the FS C8020MFP or have I something to do

THANKS
