Don't think it's your drum. Simply the fuser not hot enough, paper too thick or toner powder got problem. Print full page only black, c,y,m. See if you can narrow down to which color or all got problem.
It's just monochrome printer.
Oh btw, the CSO also said another thing that I didn't know about laser printers.
That I should try to print something at least once a week, even for laser printers. Otherwise there would be problems.
This one makes sense or not? I thought laser printers' toner dun dry up one?
