No instruction for WF-2850

Recommended Posts

Hi, 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.

Hello!
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!

Hi,

I was correct in that the printer could NOT be updated due to the non-Epson print cartridges were still in the printer, (and thus Epson was complaining).

Once I purchased Epson cartridges, the process began as one would expect!

Problem now is, per directions above, the update did NOT get stuck between 70/80%, instead the update ran till about 98% and then complained it had not been successful??

Please assist!!
