Hello
Unfortunately the scratch on the drum cannot be removed, as the drum is a organic material.
The drum and drum cleaning blade will have to be replaced.

Hello sir; When it said need maintenance, it means need PM( periodical maintenance) that including drum, drum blade ,developer, corona wire, etc. the fuser and pressure roller depend on condition.

Hi there

send a print / copy through the machine stop the machine via the main switch before toe paper has come out remove the drum unit
you should now be able to see part of your print on the drum if you can also see the black line check for obstructions in the light path if these seem fine the chances are the dev or cleaner blade seals have spung a leak ( time to replace the drum cartridge
