INKCHIP - Chipless & Adjustment Program Solution

Recommended Posts

I have tried about a dozen times to update the firmware on my Epson WF-4730. The process begins each time, and then I get the message that the printer could not be updated. I am given prompts of things to try. I have tried all of them, and always get the same message. I have tried with just the network connection, just a USB connection, and with both, all with the same failure.

One thing I did notice is that when I power the printer on as instructed, touching both the power button and the upper right corner of the touch screen, I do not get the black screen with "Epson Printer Program Update Mode" that is shown in both the printed and video instructions. It just turns on normally, and once it gave me the message not to touch the screen. However, the Firmware registers my printer as "ready and standing by."

I would appreciate your help figuring out how to update the firmware on the printer. And if it is not possible, how can I get a refund?

Thank you!

Rebecca

Hi!

Please try this new file for you.

 
https://inkchip.net/download/INKCHIP.net_Firmware_99_WF4790_v1.rar
 
1) Upload firmware which I sent
 
2) Switch on in normal mode(!!!!) just turn on button . - dont put printer in Program Update mode. (no need to press few buttons while turn on the printer)
 
The uploading process will stuck at 70-80% - it is ok!
 
Open task manager and stop updater process.
 
Printer will blink for about 5-15 minutes - then will power OFF.
 
Now power on the printer - chipless firmware is installed in your printer!

Hi!
What mode did you install the firmware in? In normal mode (using one button) or in update mode (using a combination of buttons). The firmware from the website should be installed in normal mode.
