Xp-7100 Chipless Firmware __exclusive__ Guide

| Error Code | Meaning | Solution | | :--- | :--- | :--- | | | Chip communication line shorted | Clean cartridge contacts. The firmware should skip this, but a short confuses the bus. | | 0xEA | Wrong region cartridge | Chipless should bypass this. Re-flash the firmware (corrupt install). | | Service Req 0x9A | Waste ink pad counter full | This is not fixed by chipless firmware. You need a separate reset tool. | | Printer Offline | Driver mismatch | Chipless firmware changes the printer's internal ID. Reinstall drivers via "USB 001." |
