Official tools increment a secure sector. Repacks often force a raw write. If the write fails halfway through (due to a USB disconnect or power loss), the counter becomes corrupt. The printer will then perpetually show "0000 pages remaining" and refuse to print.
Warning: Using third-party resetter tools voids your printer warranty and can permanently damage your printer if misused. Proceed at your own risk. epson resetter tool eworaexe repack
