John_Admin 388 Report post Posted December 20, 2019 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.zipStep 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!
