While this does not prevent the printer from functioning, it can be confusing for users expecting a full 100% reading.
Kael sat in his shop weeks later. The rain was still falling in Neo-Veridia. His inbox was flooded with thank-you messages and bug reports for the software he’d written. He watched the printer humming in the corner, printing out a schematic for a new project.
According to forum discussions, the widely circulated software by Lutov A.N. "worked only with SECDP1, and the chip ML-1670 has SECDP3". When the author discontinued development after his software was stolen, no updates were released to support newer chip variants.
In essence, by rotating chips between cartridges and resetting them before they become blocked, technicians can indefinitely reuse a pool of chips—each chip is never returned to the same printer twice.
If using the same cartridge multiple times, the printer might flag the serial number. It is recommended to swap chips between cartridges to avoid serialization issues. S3cc921 Chip Resetter Software
: The toner chip is connected to a PC via a hardware programmer (such as a cheap USB-to-I2C programmer like the CH341A or an Arduino).
The S3cc921 series is a specific type of cryptographic chip used by Samsung in its printer consumables. It is commonly found in printers like the Samsung ML-1640 series and was designed to prevent the use of refilled or third-party cartridges.
This section contains fixed data blocks, such as region codes or manufacturer markers. The software can read this data and, in specific cases where the chip constraints allow, overwrite parameters before they lock permanently.

: Reusing the plastic cartridge shell prevents electronic and plastic waste from entering landfills.
: Once a pre-programmed page limit is reached, the chip sends an "End of Life" signal to the printer.
"You take the cartridge CRUM, place it in another cartridge, and clear it. Afterward, the printer unit is confident that it has a new cartridge. The taken chip can be installed in another cartridge. This method eliminates potential problems when using CRUM with one serial number, as the device monitors the serial number."
