Try cleaning the LED print head which can be found laying across the copier when you open the toner deck cover.

This model is discontinued.

I would not purchase a new toner in the hopes it will solve the image quality issue.

You can also remove the drum unit and inspect the drum.

thank you so much for your help,
i checked the internet and can’t find where the led print head is for this model, the instructions are only for color models only. I took a picture of the whole unit, can you please mark where is the led head so i can clean it. also i noticed lots of toner dust in the buttom compartment when pull up. please see the picture. I cleaned that, but after couple of printing it filled again, what could be the reason? IMG_8408.jpgIMG_8411.jpgIMG_8409.jpgIMG_8410.jpg

You need a new Drum Unit. The 'green toner roller' you tried to clean is scratched hence the repetitive marks on the left side of the print page. The LED print head is located under the Top Cover.

thank you for the answer, i ordered new drum unit and toner, will see if that works,
how about the toner dumping what can cause of that?
can you please help?

The toner dumping must be because of the Drum Unit leaking through the developing roller-leveling blade.
