Hy,i have a xerox 4510 printer and i wold like to know how many pages can i print continuosly without overheating the fuser.
All of them.
The Fuser won't overheat, it will heat up and cool down throughout the job (pages will come out slower during cooldown phases)
Nobody can give you a number because it will differ by job and stock (A page of solid coverage needs way more heat than a page with a small letter D in the center and no other content)
