Konica 2060L Print Issue

[buttyoldskool]

Hi guys

I have recently aquired a Konica 2060L I am slowly finding my way around. I have an issue with prints, can anyone tell from the attached what this could be please? I have a line going across the page (in direction of the pen), and what looks like speckles on the magenta colour. Thar bar you can see on magenta is where the transfer belt has creased a little (it was sat around for a long time), thinking maybe this could iron itself out in time? If not will get the belt replaced

Thanks
