The standard Epson XP-7100 is a hungry beast. Genuine Epson 702 ink cartridges are notoriously expensive. At the time of writing, a full set of 702XL high-capacity cartridges can cost nearly as much as a refurbished printer itself. This leads to several pain points:
A: Not necessarily. Try holding the Power button for 15 seconds. Then disconnect AC power for 10 minutes. Reboot. If it still shows disabled, the NAND is corrupted. You need a JTAG programmer.
Once chipless firmware is installed, you must never update the printer via Wi-Fi or USB. However, because the printer is modified, future Epson updates cannot "break" your chipless status unless you manually allow the update.
The XP-7100 uses Epson’s "Epson Connect" or similar firmware architecture. There are two main methods to achieve a chipless state: xp-7100 chipless firmware
In most jurisdictions (USA, EU, Canada), modifying firmware for personal use is not illegal. However, circumventing chip authentication could violate the DMCA's anti-circumvention provisions in the US if done for commercial gain. For home users, enforcement is virtually nonexistent.
You do not need to be a programmer to install chipless firmware, but understanding the basics helps avoid mistakes.
If the risk of chipless firmware scares you, consider a compromise: Auto-reset chips. The standard Epson XP-7100 is a hungry beast
These are small circuit boards attached to refillable cartridges. When you turn the printer off and on, the chip resets to "Full." They are not "chipless," but they mimic the effect.
Pros: No firmware flash required. Safe. Reversible. Cons: You still have chips that can fail. You need to buy specific auto-reset chips for the 802/822 cartridges.
To understand the hack, you must understand the boot process of the XP-7100. Once chipless firmware is installed, you must never
The printer contains a NAND flash memory chip on the mainboard. This memory stores the firmware. When you turn on the printer, the CPU loads this firmware into RAM.

Chipless Firmware:
A developer decompiles the original Epson binary, finds the subroutine that checks the chips, and replaces it with a NOP (No Operation) command. Essentially, they tell the CPU: "Skip the chip check and assume full."
The modified firmware is then repackaged and flashed to the printer using a specialized tool (like WICReset or a bootable USB drive).
