Pantum P2000W Printer [closed]

Have printed forever on this very versatile A4 black and white laser printer and then all of a sudden it wants to print a blank page and then print half a page, which gets stuck causing a paper jam. Clear it all down and all is well and then we go through the same process. Updated drivers paper orientation size edge picked all the settings and have been through about every tutorial there is available to no luck. Roller cleaning, sensor cleaning, factory reset the whole lot. I know the answer is throw it away and start again but its been so reliable it just seems thee has to be a simpler answer than that.
