Now, let’s address your problem with the H43 error code.
What Does Error Code H43 Mean?
H43 Indication on Epson printers is Printhead Temperature Failure. This error usually indicates one of two things:
- The printhead has been damaged and is either overheating or malfunctioning.
- Mainboard Failure: A malfunctioning mainboard in the printer is causing a failure in communication with the printhead.
The nature of this error does not allow for immediate fixes. Often, it means hardware has failed, and you can't fix it by the usual means.
H43 error code resolution steps
Power Cycle the Printer:
- Pull the printer power chord to switch off the printer.
- The internal parts may take around 10 minutes to settle down.
- Unplug the printer and then turn it back on.
- If you continue to get the same error, go to the next step.
Check the Printhead and its Connections:
- So, if you're familiar with opening the printer, inspect the printhead visually for burn trails or scorch marks.
- Could you please check that all cables between the printhead and the mainboard are connected and not damaged?
Replace the Printhead:
- Since the H43 error is precisely due to the printhead failure, the only possible solution is usually to replace the printhead.
- Install a compatible replacement printhead following the manufacturer’s directions.
Seek a Repair Man for Mainboard Repairs:
- If the printhead replacement does not solve the problem, you may need to repair or replace the mainboard.
- A professional technician can diagnose the mainboard issue and provide a solution.
Important Considerations
Most errors are very complex to fix, but error code H43 can only be fixed by a person with advanced tech skills and special tools. These tasks may feel a bit daunting, so if you’re not comfortable with them, please seek professional help.
