HP Laserjet 9050 black area on the bottom of each page

[printer]

The area of each printed page is black. On the front page it is more grey and it is from left to right of the bottom page (a third cm width). On the back page it is only from the left ca. 4 cm to the right.

I replaced the toner, and I replaced the duplex. Where do you think could be the problem? Thanks !!!!!

Probably the fuser...you should be able to pull it out and check the rollers for visible wear.

Thanks!!!!! I replaced the fuser but the problem was still there.

It was the small roller below the toner. It is the long roller that transfers all the toner on the paper. I replaced it with another one and now it works.

With that kind of a printer you either need a maintenance service or you need two printers to check everything out.
