This is a common cause I've found, cleaning the drum doesn't do any good as
it doesn't tackle the cause.
Of course if the drum itself is actually worn then nothing will help.

Do you mean scrap the cartridge or the scaper?

You can (I've found) actually replace a worn blade. It's a bit of a messy
job though.
You buy a spare blade from a drum remanufacturer wholesaler, in the early
days laser drums were apparently built to survive, so a remanufacturer could
often just replace the toner and the blade, later on drums, and associated
parts were designed down to last not more than the length of the toner.

But first I'd check the corona wires. You should clean them with any sort of
volatile solvent.
