DRUM LIGHT FLASHING NOT PRINTING - Brother HL 5250DN Laser Printer

Refer to Brother International - Support for your Brother Product .

We have just changed our drum unit but the drum light is still flashing. The printer is printing though. Any suggestions?

Follow the link below to see what the light flashing mean.

The flashing means that the toner and/or the imaging drum is empty or missing (printing halts on these errors). Lights on steady means low toner.

Imaging drum is empty or missing (Error 40204) Light pattern Description The imaging drum is empty or missing. The imaging drum light is blinking, and then printer stops printing. An error 40204 is written to the event log. The printer cannot detect the imaging drum correctly. Action

1. Reinsert or replace the imaging drum.
2. If the imaging drum light is still blinking but the Attention light is not on, turn the printer off, and then back on.

When the Imaging Drum LED stays solid on, it means your imaging drum is running low and will soon need to be replaced. You can unseat, then reseat it and see if that solves the problem.

If everything is printing fine, don't do anything until the LED starts flashing. HP will tell you to replace the drum immediately, but mine was on for a year, with moderate printing, before going to the flashing, "empty" state. This is the same advice as for toner cartridges, which are sometimes as much as 50% full when the light comes on.

However, I suggest sourcing a new drum so you can be prepared for when the existing one goes out. Also, despite HP's warnings of gloom and doom, aftermarket products work acceptably.

Try resetting the drum counter:

open the front cover, press the blue button and keep it pressed until all the LEDs are lit - hold for a few seconds and then close the front cover.

Might have a paper jam in area of toner and drum cartridge that may need to be removed. Typically this will solve the issue.

Replace the fuse on the bottom of the drum cartridge.

First unplug power cord and plug back after 10 mins.
If problem persists, then it is probably a toner error, if the toner is nearly finished. In this case you will see the led flashing only when is printing. Sooner or later the printer will start printing blank or faded pages and you will need to change toner
When is not toner, with same symptoms as above, it can be drum error, in this case printer will keep printing but shows flashing light, at a certain point you will need to change drum kit.

If light flashes and printer does not print, then it is either paper jam inside, or one of errors above at final stage, or one of the door not well closed (check them all), or printer faulty (fuser, heads mechanics etc.), in this last case call service.
