WF-2850

Recommended Posts

Hi,  I might have posted this question in the wrong topic earlier. I'm reposting it here. 

When opening the pdf file with the instructions for the Work Force 2850, I got this file:

"Instructions for updating the printer firmware in chipless, method 9 Compatible Epson Printer Models: WF-2630; WF-2631; WF-2650; WF-2651; WF-2750; WF-2751; WF-4630; WF5620; PX-M840F"

NO 2850 mentioned... How do I enter firmware mode for the Epson WF-2850?

Thank you for your help.

Hi!

Please try this new file for you.

 
https://inkchip.net/download/INKCHIP.net_Firmware_99_WF2850_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!
