Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.

Sorry to hear you’re having trouble.

What is the make/model of the printer?

Customer: replied 1 year ago.
Brother HL-4150CDN
Expert:  Nathan replied 1 year ago.

Does it happen on all print jobs?
In black and color?

Are you using genuine brother toner, or generic/refilled cartridges?

Customer: replied 1 year ago.
all print jobs. Black and color. speckles appear to all be black.
Yes we use genuine brother toner
Expert:  Nathan replied 1 year ago.

Thank you for confirming.

Take the toner out (black) and give it a good shake side to side.

Then slide the blue/green plastic tab on the black drum side to side at least 5 times to clean the corona wire.

Put it back and try to print again.

If still no change, then you have a bad drum. We can try manually cleaning it, but it will most likely need to be replaced:

Customer: replied 1 year ago.
Already did the shake side to side and the plastic tab numerous times.
In fact, just prior to contacting you but I'll try it again... Nope, still the same.
If the drum is bad, why did no error message come up?
Expert:  Nathan replied 1 year ago.

Because the drum is not actually degraded to the point of full failure yet,

and the drum fail messages really only come up based on print usage, it is based on page count.

You are having print quality symptoms that indicate a drum fault, even if it has not reached its actual end of life stage.
