WF-7710 - doesnt see Maintenance Cartridge

Recommended Posts

I have Epson WF-7710
I have used Chipless Solution to make it chipless- all was ok
Now my maintenance cartrige finished and need to be reset or replaced.
I have used Chip resetter which I always use to reset Waste Cartridge in my WF7710 - it show green light - reset ok

But after I install it back in printer - printer doesnt recognize it.
Then I installed new maintenance cartridge - the same problem - doesnt see.

How can I solve the problem?

Some times this can happen. Here is step by step solution:

Step 1. Make firmware downgrade by WIC Utility to FA27HC version. You will be required Firmware Key to make this procedure.

Step 2. Check current firmware version - it has to be FA27HC.

Step 3. Install new Maintenance Cartridge or reset by Chip Resetter chip on maintenance cartridge. Check if printer can recognize it now.

Step 3. Download and extract latest Chipless Firmware Version - FA99Z9 - http://chiplesssolutions.com/download/WF7710_FWG535TL_FA99Z9.zip

Step 4. Upload firmware to  printer in normal mode  - dont put printer in Program Update mode.
The uploading process will stuck at 70-80% -  it is ok!
Printer will blink for about 5-15 minutes accepting new firmware - then will power OFF.

Step 5. Open task manager and stop updater process.

Now power on the printer - chipless firmware is installed now in your printer and maintenance cartridge is recognized by printer!

If You have problems - give us screenshots of what You cant do and what Step you cant perform.
