Hi Have you tried contacting the seller or taken the operating manual of the printer? -- Please: No text messages and provide as much information as possible to respond to you (Also, let us know what you did before your issue arose..)

Hi, thanks for your response. In the manual, it asks to check the fan or the control board. So I checked the fan, it's fine, but by pressing the switch off and on for at least 30 minutes, it works, and the next day the same code E805 appears again.
