We have a Brother HL-5240 which is currently printing with long black smudges on the paper.

straight paper path. take out tray and toner.. pop down back the paper will be in one of the places.. check for nicks or damage to leading edge of the paper. If its labels get back to us.

Change drum or wiper blade

You probably printed a document that was forced to the manual feed. Place some paper there and it should print. Go to your printer preferences and set the default tray to tray1 instead of Auto.

The smudge is probably due to the pinch roller having some toner on it. Try cleaning the inside with a solution of alcohol and water a 50/50 solution should work. Don't use alcohol full strength.

You will need to use the manual feed slot which is above the paper tray.

The manual feed is meant for labels and envelopes

Make sure the end tab in the paper tray is not too tight. The tab where you set the paper length. The paper should have about 1/16 inch space and not hold the paper too tight.

This usually means a print job is stuck in the queue that was set to "manual feed" or to a different paper size, such as legal. Add paper to the front manual feed and press "Go". If this is the problem, the stuck document will begin printing from the manual tray.

To clear the problem without printing from the manual feed, cancel all jobs on the printer, delete any jobs out of the Windows print queue and restart the computer.

The drum light will flash on my brother HL-5240 Laser Printer when printing but it continues to print just fine. Does this mean the drum needs to be replaced?

you need to change driver configuration
very easy
