– Connect the SOIC-8 clip to the S3cc921 chip on your cartridge's small PCB. Ensure pin 1 aligns (marked by a dot or notch).

Managed primarily through hardware programmers like the CrumProg Programmer or custom I2C adapters, this software targets the S3CC921 series microcontroller family (including SECDP-3, SECDP-4, and SECDP-5 profiles). By utilizing this software, remanufacturers can bypass artificial page-count limits and safely reuse original laser toner cartridges. What is the S3CC921 Chip?

| Problem | Solution | |--------|----------| | "Chip not responding" | Check clip connections. Clean chip pins with alcohol. | | Software crashes on Windows 10/11 | Run in + Admin rights. | | Printer still says empty after reset | Some printers have a secondary counter in the drum unit. Reset that too. | | Chip permanently locks after 2 resets | The S3cc921 on newer HP cartridges has one-time OTP bits. You need a new chip. |

The printer tracks chip serial numbers. If the software reset the page count but did not change the serial number, the printer will remember it as empty. Ensure the software changes the unique serial string.
