What have you tried so far?

Most likely the yellow drum needs replacing.

You can swap the colour drums around for troubleshooting.

The print samples are great help but need more information because several things can cause that poor quality.

What do the consumable life counters look like? If anything at "0"% replace those items.

Like the other poster said have you tried anything before posting here? Most techs at least try the basic things before posting here, i.e. cleaning print heads & coronas, swap drums, look and see if dev units dumped or starting to dump, etc etc
