I can't see the other developing rollers, but the yellow developer is definitely depleted. Do you see the "barber pole" pattern lacking developer?

CE40 means that the patch sensors are not seeing some of the color patches on the belt. It would be informative if you took photos of the developing rollers of each color. =^..^=

I also realice that the transfer belt its broken and you can see the color path on the belt, and yelow its different.

so I belive that i have to start changing the transfer belt and then replacing developer material. Its that correct?

With developing rollers do you mean developer sleeve?

... when you say barber pole you are referring to multiple places along the yellow developer magnetic roller where there is no yellow developer present.

This is because there is no longer enough developer inside the developer casing to coat the mag roller. Correct?

The CMYK on the outside of the developer units is just toner dust correct?

Does the presence of this toner dust mean anything to be concerned about other than just clean it off?

Yes, it's the same as the "developer sleeve" or "mag roller" (magnetic roller)

Yes, exactly.

Firstly, if the machine errors out, it is normal to see patches on the transfer belt, but I only see one row of patches. We should be seeing patches at the front AND the rear of the transfer belt.

The toner spray on the top of the developing units on the top of the developing units looks to be what I'd expect when the machine was ready for all (4) developer changes. The developer density will become richer as it nears replacement. When it becomes this rich, just vacuuming will not help for long. It will continue spraying.

@SalesServiceGuy: Does my American English terminology vary from what you'd say in Canada? I know you've seen these effects ... what would you call them? =^..^=

So, first I Should change developer material in the four collors and then see if the color paths are formed on the tranfer belt, rigth?

Before you get too deep into this install are you prepared to spend over $1,000.00 on CMYK Developer material plus other parts?

Is the customer on a service contract and how long will it take to recoup this investment because in the end even if the repair goes perfect (you sound unexperienced/so perfect is unlikely) you will still end up with an old discontinued copier waiting for the next part to break or wear out.

I think this copier is borderline uneconomical to repair especially if low colour volume is expected.

The e2050c was introduced in May 2016. Expect Toshiba Tec to officially discontinue all support in May 2023 meaning no more OEM parts and toner.

If low colour, I would only replace the black developer and drum, lock out the colour with a Dept Code and tell the customer you now have a black only copier unless you want to pay for all of these parts up front.

.. I have heard the phrase "barber pole" before but I appreciate your explanation. I am trying hard to get all e2050c/ e2555c series copiers out of my area of responsibility.

Re: Toshiba e-studio 2050C Error CE40

@SalesServiceGuy: I can certainly understand that. But since most of the parts are the same as the Weisshorn Low/High Series (FC30/FC50) we should be able to keep them going a little longer.

@leonardom57: Cost is a serious consideration. Have you printed off the maintenance list yet? Yes, you could run into thousand(s) of US dollars spent in parts. Are you (or your customer) prepared to pay that?

I would make up a wish list, and price out everything you want. That could be enough incentive to get them into a new machine. Also keep in mind that you cannot make any samples yet. There is probably more in need of fixing. =^..^=

Re: Toshiba e-studio 2050C Error CE40

Im the owner of the machine, I am looking for technicians in my area who are willing to repair it but it is difficult for them to get the parts

also im unexperienced but I was able to disassemble all the cleaning units without problems following the technical manual.

It would be great to be able to get the machine back up and running at least keeping the color black, or at least keep the scanner and email function which was working without problems.

I think the biggest problem its the transfer belt, There are a lot of sellers on ebay / aliexpress that sells the transfer belt for very cheep price, but i dont know if it will work. also I can get developer material at local store. Im not expecting to make a perfect repair, just make it work.

It would be great if you can guide me on where I should start.

Re: Toshiba e-studio 2050C Error CE40

Update:

The printer was turned on and it started normally, no printing was done because the transfer belt rubs inside the printer.
I guess cleaning the "Cleaning Units" worked but the machine will remain off until I can replace the transfer belt.

Re: Toshiba e-studio 2050C Error CE40

Do you have a manual?

You should start by examining the primary transfer belt cleaning unit. That "rubbing" sound is usually the cleaning auger bound up. You certainly do not want to install a new transfer belt along-side a damage cleaning unit.

You should look at that. =^..^=

Hi, I cleaned the cleaner unit and the rubbing sound is gone.

I turned on the printer and the error disappeared, the printer its working normal printing in black.

I had developer material for the colors CMY And I want to change it.

I would like to start with yellow and see if it works.

I read on the service manual that I have to perform a "Adjustment of the Auto-Toner Sensor" after change the developer material.


Its that correct? should i do anything else?

thanks, Regards.

Re: Toshiba e-studio 2050C Error CE40

First vacuum out the yellow developer, and refill with new yellow developer.
Reset the appropriate counter in 6S-2. If you've got the manual I think you'll be able to figure it out.
Then stir the yellow developer in 05-2401.
While you're still in 05 mode, run 05-2742, 05-4719, 05-4Fax, 05-7869, 05-70Fax, 05-8008, 05-230Fax, 05-8009.
You'll find details in sections 6.1.2 just take your time, and read the details. =^..^=
