Did your Epson L120 printer suddenly turn itself off? No need to panic, find out the causes and how to overcome them in this article.

How are you? Hopefully you are always healthy and don't worry about your Epson L120 printer having problems.

Yes, it's also an electronic item, so there will definitely be problems, especially if the printer has been used for a long time.

However, from Mimin's experience, repairing a printer that suddenly turns off is sometimes very easy because it turns out the cause is quite simple, for example just the plug cable is broken.

Although in some cases, we are required to disassemble the printer because the source of the problem is in the machine components.

The shutdown process itself can vary, some turn off shortly after turning it on, turn off when it is used to print, and there are also things that turn off when it is first turned on where the power button does not respond.

However, you can rest easy because in this article Mimin will share solutions that can be used as a guide in dealing with an Epson L120 series printer that suddenly turns itself off.

However, before that, it is important to know in advance what things can cause the printer to suddenly turn off.

OK, just look at the description...


Reasons why the Epson L120 printer suddenly turns itself off

How to deal with the Epson L120 printer suddenly turning itself off


For your information, an Epson L120 printer that suddenly turns itself off is often caused by a broken plug cable, damaged adapter/power supply, damaged power button, or it could also be due to a problem with the mainboard.

Let's discuss the causes above one by one...


1. Plug cable broken


It's trivial, but quite often it happens that the Epson L120 printer suddenly turns itself off due to a broken plug cable.

As a result, the electricity flow from the source to the printer is also cut off, causing the printer to suddenly turn off.

This plug cable can break because it may have been folded or pulled hard enough to cause the conductor inside to break.


2. Damaged Adapter/Power Supply


Inside the Epson L120 printer body there is an adapter which functions as a power supply to carry out all printer functions.

A printer's adapter consists of a series of various types of electronic components that control the power that will be distributed to the machine.

If the Epson L120 printer suddenly turns itself off, it could also be caused by damage to this adapter component.


3. Power button is damaged


The Epson L120 printer power button is a switch that is integrated with the mainboard unit and is responsible for the printer ON/OFF mechanism.

The normal power switch will turn on the printer when pressed, which is indicated by the indicator light turning on. It often happens that the Epson L120 printer cannot be turned on due to damage to this component.


4. Mainboard Problem


The mainboard or engine is a vital component of a printer because it is in this component that all printer functions are carried out.

On the PCB of the Epson L120 mainboard circuit there is a component called IC power which functions to distribute voltage to other components so that the printer turns on.

Most problems with the mainboard are often triggered by damage to the power IC component causing the printer to suddenly lose power and shut down.


5. Printer Head Short Circuit


Many people don't realize that damage to the printer head component can cause the printer to suddenly turn off. It is important to know that most cases of mainboard damage are caused by problems with the printer head component.

Even though its function is only to remove ink, this component also contains electronic circuits which are prone to short circuits if exposed to liquid.


How to deal with the Epson L120 printer suddenly turning itself off


To deal with an Epson L120 printer that suddenly turns off, we can carry out the easiest inspection steps first.

  • Check the condition of the plug cable, to be more sure, look for another plug cable then plug it into the dead printer.
  • If the printer can turn on, then it means the plug cable is broken, but if not then we continue to check the next component.
  • Take out the printer adapter/power supply which is located at the back of the body, try to find another adapter and plug it into the printer, if it lights up then it means the adapter is the problem.
  • If it remains off, then we continue to check the Print Head component.
  • Open the print head, then check whether there is a possibility of a short circuit or not. If the print head is fine, then we continue to check the mainboard.
  • Open the printer casing to see the condition of the mainboard, check the condition of the power switch, fuses, transistors and power IC.
  • If one of the mainboard components above has a problem, repair it immediately or if not look for a replacement mainboard. 
  • After carrying out the steps above, usually the printer can immediately turn back on.

Conclusion


So, an Epson L120 printer that suddenly turns itself off is often caused by a broken plug cable, a damaged adapter/power supply, a damaged power button, or it could also be because the mainboard has a problem.

That's the description of how to deal with the Epson L120 printer suddenly turning itself off, share if you find it useful, thank you.
