repeating image

[Kirkc]

Hi, I have a problem that is stumping me on a ar-m455. I was called to a customer with lines on copies...I got there and the unit had several problems, first corona streaks, then a line caused by a scored fuser roller, and also a whole page shading. I replaced entire drum unit with one that was known to be working and also before taking it to customer I replaced drum, and blade and completely cleaned corona. Then replaced fuser, and developer unit with known working one also replaced charge roller from working unit. Replacing those parts got rid of corona streaks and fuser lines, cleaning ground spike got rid of shading but... the repeating image remains. I interupted the copy and the repeated image is coming from the drum not the fuser. the latent image is still on the drum and the blade cleans it off if you manually rotate drum when drum unit is removed from machine, but during copy process the latent image remains. This sounds like a ground problem so I cleaned all contacts between the drum unit and machine. Any help would be appreciated, thanks

Did you try to change toner? Of course, you'll need to empty the dev unit too.

What would changing the toner matter? This isn't inkjet.

Re: repeating image

It could be generic toner. And you'd have to change the toner and developer to see the difference immediately.

What is the interval on the repeating image? How many millimeters? =^..^=

Man, you must be the luckiest if you never faced bad toner problems. A couple of days ago I've seen non-marked toner on Kyocera KM-1635 that doubles the toner layer on mag roller. So it would be worth to try to change it I suppose.

the interval between the primary image and the ghost image is 95 mm. I am going to that customer here shortly to check all dv, seperation and charge voltages, and with a new sharp toner and new sharp dv and see what happens

If you only use OEM toner, you don't tend to have toner problems...

It depends on how long it was in storage.

Re: repeating image

as far as the toners we use, we use katun toners almost exclusively and a katun toner was in the machine at the time we were having the problem but... when I showed up there today the problem was gone, I don't know why maybe something i did last visit but when I was last there the repeating image was very noticeable. Thanks to everyone for all the help! I hope it does not return but for now I will just go with it is working.

Again, not a relevant issue with proper inventory management. Let's not debate semantics here, though.
