How to fix printer with these fatal error information

After determining the error code your Epson L350 printer is experiencing, look in the table above for a description of the error code, then in the corresponding 3rd column you will see the possible causes of the above error.

Check the causes one by one and fix them.

Here are some tips on how to fix the Epson printer error using the information provided in this post:

Identify the error code => Follow recommended solutions => Seek additional help => Prevent future errors

It’s important to remember that while these errors can be frustrating, they are not uncommon, and there are steps you can take to prevent them from occurring in the first place.

Regular maintenance and proper care of your printer can go a long way in avoiding fatal errors and extending the lifespan of your device.

How to fix Ink device error.

In the table above we also see that there are many different error codes but the same description and cause, such as the error “Ink device error.” This is because depending on the situation, depending on the case of an error related to “ink device”, there will be different error codes.

However, the solution is to fix the possible causes:

+ Ink cartridge failure.

– Check if the ink cartridges are properly installed and seated in their holders.

– Replace the faulty ink cartridges with genuine Epson cartridges.

– Clean the contacts on the ink cartridges and the holder board assy.

– Reset the printer by turning it off and unplugging it for a few minutes before plugging it back in and turning it on.

+ Holder board assy failure CSIC terminal failure/CR contact module failure.

– Check for any visible damage or debris on the holder board assy, CSIC terminal, or CR contact module.

– Clean the contacts on the holder board assy, CSIC terminal, or CR contact module with a soft, lint-free cloth.

– Replace the faulty holder board assy, CSIC terminal, or CR contact module if necessary.

+ Main board failure.

– Check for any visible damage or debris on the main board.

– Reset the printer by turning it off and unplugging it for a few minutes before plugging it back in and turning it on.

– If the issue persists, replace the faulty main board with a new one.

It’s always a good idea to consult your printer’s user manual or Epson customer support for specific troubleshooting steps before attempting any repairs or replacements on your own.

Hope these solutions help you resolve the Epson L350 errors you’re experiencing. Good luck!
