I'm going to take out the transfer belt unit and clean the image quality sensors and also the belt following the "service manual"


Do you recommend to clean something else?

I will check is the transfer belt cleaning unit, the auger spring always came out jamming the transfer belt unit due to harden toner inside the nozzle...
Next, check whether the transfer belt can turn properly, the bushing on the belt unit will jam...

Thanks for the reply,

I will check that, but the transfer belt is not jam, it can rotate without problems, the problem is that printed sheets came out with the same color pattern as the belt. I will clean the belt and the sensors on the Image quality control unit and also check that auger spring on the transfer belt cleaning unit. I hope it's just that.

then also I will perform the instructions on the service manual:

8.3.21 Image control related service call

your problem IS NOT settings in the machine.. you have a BELT CLEANER PROBLEM. change belt cleaner or empty waste in there... clean and powder the cleaning blade.

Ditto that. Since those patches are so nice and clear I'm thinking that you either have no transfer cleaning unit at all or it's seized solid and the gears broken. =^..^=

yes, you were right. the auger spring came out and there were small pieces of harden toner in the clean unit, fortunatelly there was not broken gears, I cleaned and powdered the cleaning unit and I also cleaned waste toner over the yellow developer unit which it's the closest to the cleaning unit. I could only do that because I did not have much time

But there is something that I couldn't understand,Why were these color patterns formed on the belt?

I mean If it was only a cleaning problem, the belt should be uniformly dirty but it has those lines of colors as the image shows.

those patterns are put on the belt for color density detection/adjustment. normal.

So, should I remove the transfer belt unit and clean the belt or not?

Re: toner lines in transfer belt unit TOSHIBA e-STUDIO 2050C error CE20

The primary transfer belt cleaning unit is designed to clean off these patches. The only reason that you might need to clean the primary transfer belt is if the cleaning unit is unable to remove the heavy layer of toner left from multiple patches. You can use alcohol, but any cleaner used on the primary transfer belt will leave a residue that takes anywhere from 50 to 200 prints for the cleaning blade to squeegee off. So it's preferable not to use a cleaner on the belt if at all possible. Run the machine to see if the cleaning unit will adequately clean the belt before using a cleaner.

You'll notice that there are two types of patches: There are the square blocks that determine the toner density and potential control settings. There are the "V" shaped marks along the front and rear edge to align the colors. It's completely normal. You just don't normally see these patches because they are formed between copied pages, or at the beginning or end of a print job, then cleaned off of the belt. =^..^=

no need once you get the cleaning unit setup right

Don't forget to put a very thin layer of toner over the belt, if you are going to clean it for any reason, before install it back in the machine.

Thanks everybody, you save me so much time. I only cleaned the cleaning unit, I realiced that somebody have putted the blade upside down so it was not making contact with the belt, now I'm testing if the belt is being cleaning property, otherwise I will change the cleaning unit.
