BROTHER Error Code 1684
MEDIUMCommon IssueBrother Error 1684: Ink Cartridge Not Detected or Installed Incorrectly
Error 1684 on Brother printers indicates that one or more ink cartridges are not properly recognized or installed.
The Brother Error Code 1684 typically appears when the printer fails to detect an installed ink cartridge, or it believes a cartridge is missing or incorrectly seated. This can happen for several reasons, including a cartridge not being pushed in all the way, protective tape still covering the cartridge's contacts, or a faulty chip on the ink cartridge itself. The printer uses small electrical contacts to communicate with the cartridge, and any obstruction or misalignment can prevent this communication, leading to this error. While often a simple installation issue, this error can also point to a more significant problem such as a dirty or damaged contact within the printer's cartridge bay, or even a defective ink cartridge that the printer cannot read. It's important to address this error promptly, as the printer will not be able to perform any print functions until all ink cartridges are correctly recognized.
- 1
Turn off your Brother printer and unplug it from the power outlet.
- 2
Open the ink cartridge cover on your printer.
- 3
Carefully remove all ink cartridges from their slots.
- 4
Inspect each cartridge for any remaining protective tape, especially over the metallic contacts, and remove it if present.
- 5
Gently wipe the metallic contacts on both the ink cartridges and inside the printer's cartridge slots with a clean, lint-free cloth or a cotton swab lightly dampened with distilled water. Ensure they are dry before proceeding.
- 6
Reinsert each ink cartridge firmly into its correct slot until you hear a click, ensuring it's seated properly. Make sure the colors match the labels.
- 7
Close the ink cartridge cover.
- 8
Plug the printer back in and turn it on.
- 9
Check the printer's display for the error message. If it persists, try replacing the suspected faulty cartridge with a new, genuine Brother cartridge.
You should consider calling a specialist if, after trying all the DIY steps, the error 1684 persists, especially if you've tried new, genuine Brother ink cartridges and the problem remains. This could indicate a deeper hardware issue, such as a damaged ink cartridge sensor, a faulty print head assembly, or a problem with the main logic board that controls cartridge detection. These issues typically require specialized tools and expertise for diagnosis and repair.
