Why is my Brother DCP-J4120DW All in One Printer only printing in B&W and asking to replace ink?
- T
  thomas73Aug 26, 2025
  If your Brother All in One Printer is only printing in B&W 1-sided and prompts to replace ink, it means one or more of the colour ink cartridges have reached the end of their life. Replace the ink cartridges. Also, the machine will stop all print operations if you unplug the machine or take out the ink cartridge, or if you select Slow Drying Paper in the printer driver.

Why does my Brother DCP-J4120DW say 'Wrong Paper'?
- D
  dylan24Aug 27, 2025
  If your Brother All in One Printer displays a 'Wrong Paper' error, it could be due to the following reasons: * The paper size setting does not match the size of paper in the tray. Check that the paper size you choose on the Touchscreen matches the size of the paper in the tray. * The paper orientation is incorrect for the paper size. * You did not set the paper guides in the tray to the indicators for the paper size you are using. * If you are printing from your computer, make sure the paper size you choose in the printer driver matches the size of paper in the tray.
