WC7830 printing problem

[houly]

Hello,
I have a printing problem : two blue spots on each page printed. This problem is visible on the x axis, I mean little side of a A4 page, I already printed support page but my problem is the axis is not the same : they mention a drum problem when spots are present on large side instead of little one in my case. The distance of those points is 95mm. Do you think it's the drum I need to replace the drum ?

Thanks for your help

Are you really tech? Long side, short side? Replace drum.
