Congratulations on your success! =^..^=

Whatever is happening is in the black developing unit definitely.

* Check to see if the seals at the front and rear of the developing unit are leaking. If they are leaking toner replace the black...

Welcome! =^..^=

If it's broken at the rear block, you can repair it like the first two photos.
If it's...

The hardest to diagnose are utilities that browse all of the IP addresses. Sometimes you can get very lucky and just change the IP address, but such utilities often hit EVERY IP address.

That may make IT & administration happy, but I'd imagine that the endusers are going to be less than enthusiastic about it. =^..^=

I also have seen various HVT issues. Before I did that though, I would try checking the driver checkbox "Print Text As Black". That may improve your image.

That must be the first thing they teach...

A Toshiba eS2540cs is a completely different animal than a Kyocera ECOSYS M2540dn. They have absolutely nothing in common. Also keep in mind that that Toshiba has been obsolete for quite a while. You...

This is so smart!

I had one of those horrible moments 16yrs ago. We were moving a CS8030 off of it's busted up pallet. It was me and three other truck drivers lifting #600. We had it lifted and...

Welcome! =^..^=

I like it. =^..^=

I can't tell you which models, but once they go into an error code the Settings Menu may become inaccessible. And if you replace the printhead while in service mode the error will remain. So if I...

There's a third & fourth choice:

3rd: Ends up under the heaviest object in the room, regardless of how far away.
4rth: Is magnetically attracted to the nearest circuit board, and the most...

Welcome from the other side of the world. =^..^=

I've never seen the official bulletin, but it's no small task. On later production models they installed a new style front cover with holes to access the screws for the waste outlet. On my machines,...

If I were to guess, I'd guess that the U021 reset cleared the speed upgrade code, so it won't accept that toner, and it will run at 25ppm. I suspect that you'll have to call the hotline to get the...

Thanks Lawrence! That video is a nice demonstration.

I like choice #2. Buy the good used replacement. You can part out the old one later on, as needed.

In a very high volume situation it will run longer than a low volume situation. That's the only...

So just to clarify: That line is crossfeed? If yes, start with the simplest of solutions: clean every rubber, metal, or plastic roller thoroughly. I use an orange oil based cleaner. It leaves the...

Correct. =^..^=

Those were my conclusions. Once the overtoning starts, replacing the developing unit is the only cure. This is not a machine that you want running 1000 pages per month. More is better, as with most...

Go with the kit. There are detailed instructions in the package. it is important to follow the documentation. If resets are not done before service is performed, it can take a very very long time for...

I'm always loathe to disconnect any ribbon cable I don't have to. They damage far too easily. This is my preference too. =^..^=
