KM 4050 light prints and copies on one end
I have a KM 4050 that is light on one end of the page. I have new oem toner and the drum has less than 2000 pages on it. I am at a loss of what it can be. Thank you

Re: KM 4050 light prints and copies on one end
What's the page count on the developer? I've had this same problem before and it was the developer needed to be changed.
Here's an example of my problem. Looks the same to me.

The developing unit was replaced with the drum I did the maintenance kit (Includes DV-715 Developing Unit, DK-716 Drum Unit, FK-715 Fixing Unit, TR-710 Transfer Unit)

Re: KM 4050 light prints and copies on one end
Are you having the problem on copies & prints?
Have you cleaned the laser slit glass?
Is there moisture in the paper?
You need to figure out if the problem is in the image formation section or the transfer section. Maybe cut the power off during the the copy process and look at the latent image on the drum.

Re: KM 4050 light prints and copies on one end
It happens on copies and prints.
I tried turning it off and the latent image looks light on the end of the drum just like the paper (I could not get a good photo of it)
I did wipe down the outside of the laser lens and can not see anything on the outside surface.
The only thing I can think of is that there is something inside the laser module or maybe the laser is getting week.
I could not find instructions to get at the laser module.

Re: KM 4050 light prints and copies on one end
The KM-4050 is a very old machine. It was released in 2006. What the total counter? Sounds like a good candidate for an upgrade.

Re: KM 4050 light prints and copies on one end
the total count is 269817 so it has not bee used that much and last year we put money in it for the maintenance kit. An upgrade is defiantly not in the budget for a copier (especially this year). That is why I was reaching out here.

Is that the kit your replaced?
Is it an OEM kit or generic?
Can you tell me every item that was included in the kit?

Re: KM 4050 light prints and copies on one end
Ok, good. Who knows how long that kit has been sitting on the shelf. I would pull the DV unit and look at the magnetic roller to see if it is coated with developer from end to to end. We know the the problem lies in the image formation section because you saw the void area on the latent image. When you pull the DV unit, shake it real good and see if that helps. Hope that helps.
