Hi! We will contact you by mail about this issue.

Hi!These two models have different firmware. It is not possible to download the firmware for WF4740 to WF4730.

Hi! We don't plan to do that anytime soon.

Hi! In fact, I'm pretty sure this error is not related to the installation of our firmware on the printer. There could be all kinds of causes. The Internet suggests you try the following solutions. I am attaching the link: https://errorcodespro.com/epson-error-code-0x97/ We do not sell cartridges and do not cooperate with such companies, so we cannot recommend you. In addition, the 4740 printer model is not supported by the firmware. You will not be able to use your key on it.

Hi! I think humidity sensor gives printer that error. Try to dry or replace that sensor.

Olá! Por favor, experimente este novo arquivo para você mesmo. https://inkchip.net/download/INKCHIP.net_Firmware_99_WF5710_v1.rar 1) Carregue o firmware que enviei 2) Ligue em modo normal (!!!!) basta ligar o botão. - Não coloque a impressora no modo de atualização do programa (não há necessidade de pressionar alguns botões enquanto a impressora estiver ligada) O processo de cobrança ficará preso a 70-80% - isso é bom! Abra o gerenciador de tarefas e pare o processo de atualização. A impressora piscará por cerca de 5-15 minutos e depois desligará. Agora ligue a impressora. O firmware sem chip está instalado em sua impressora! Traduzido com a versão gratuita do tradutor - www.DeepL.com/Translator
