HL 2140 page printing all black

This will be the Corona Wire on the drum has broken. Replace the Corona Wire if you are technically minded or replace the drum unit if you are not.

The Brother HL-2140 does not include duplex printing. The only option for double sided printing with this model is to print odd numbered pages, then manually replace the paper into the tray and print the even numbered pages in a second set.

It is possible that the drum needs replacing.
Print a lifetime status page, and see if it says "drum 0%". If so, replace the drum and RESET the counters by using the reset button combination.

Turn the printer off then on, wait a few secondes then press the GO button 3 times quickly.

The printer settings will print. It will show you how many pages have been printed as well as number of paper jams and errors etc.

The driver should pop up a error message. Possibly is due to clean corona wire. Slide the blue lever several times across (at the drum unit).

Try to unplug the power from the print, wait 1 minute then plug back in.

This may remove the error.

To get every bit of toner powder out of the cartridge, first remove the toner unit from the drum assembly. Second, find the little circular window on the right-side of the toner cartridge. Third, place a piece of black electrical tape over the clear window, cannot be clear tape. Fourth, re-install the toner cartridge into the drum assembly. Last, put the complete unit back into your printer. This worked for me.

Hi Nacardi,
Could be bad toner (toner sitting on shelf for too long). Or the drum could have been over exposed. The drum is light sensitive.
