The "E4 16" error message on a Lexmark CS410dn printer indicates that there is a problem with the printer's toner cartridge. This can be caused by a variety of issues, such as:
- The toner cartridge is not properly installed in the printer.
- The toner cartridge is not compatible with the printer.
- The toner cartridge has reached the end of its useful life and needs to be replaced.
- The printer's firmware is out of date and needs to be updated.
To resolve the issue, you should try the following steps:
- Turn off the printer and unplug it from the power outlet.
- Open the printer's front cover and ensure the toner cartridge is properly installed.
- Clean the electrical contacts on the toner cartridge and the printer with a dry, lint-free cloth.
- Reinstall the toner cartridge in the printer, being careful to align it properly.
- Turn on the printer and check if the error message is cleared.
If the error message persists, you may need to check the compatibility of the toner cartridge with your printer model, and the age of the cartridge. If the cartridge is old, you might need to replace it with a new one.
Updating the firmware of the printer can also solve the problem, check the Lexmark website for update on the same.
