It could be that the Scotchmark is unable to pick up enough of the
toner, leaving a lot of the drum which then gets transferred onto a
slightly later part of the page.
In theory, the drum wiper should clear the excess toner off the drum,
but I have found certain media doesn't hold the toner well and creates
these "ghost images sometimes.
Adhesive fails over time, so if you have either an older batch or a bad
batch (sometimes it isn't made properly either) that can cause issues,
and it may be the consumable at fault.
