Lines On Top Of Printouts

Any ideas what might be causing this to happen on a HP Colour LaserJet 5225n?

 

I've removed the toners and cant see anything on the OPC drums and I've swapped the fuser unit over with one from another printer of the same model and it's still printing these lines at the top of the page.

Transfer belt has skidmarks on it perhaps if it has a separate transfer belt?

I can't believe I didn't check that!

There were no visible marks on the tranfer belt, we even gave it a thorough air-dusting but they still appeared. Fortunately we have one in IT Services so we swapped it over with the one in that and the lines disappeared so problem solved!

Glad that solved it the belt is probably worn / got a small mark on it / puddle of old toner stuck, give it a good manual rotate and clean and should be fine

Cleaning didn't make any difference. I even took it outside and gave it a good air dusting - wow there was a lot of loose toner in the mechanism as it formed a great big dust cloud in the car park!!!

 

I swapped it out for the one in our office and it now prints OK and I have a replacement on order to sort our one out
