Our upgraded Lexmark 66S1000(for Lexmark MS531/631/632/MX532/632 series machines) toner chip now features a doubled serial number library, expanding from over 40 sets to nearly 100 sets — the largest serial number coverage available in the North American aftermarket.
Frequent Lexmark firmware updates often cause chip recognition failures, device rejection and frequent customer complaints, which are major headaches for toner remanufacturing factories, refill vendors and MPS service providers. Our massively expanded serial number pool effectively solves this common industry pain point, covering almost all mainstream firmware versions of the targeted Lexmark devices.
With richer and more updated serial number resources, the 66S1000 toner chip delivers significantly higher compatibility and recognition pass rates. It greatly reduces chip errors, product returns and end-user complaints, helping North American aftermarket partners lower after-sales costs and improve service credibility.
Maintaining stable counting performance, plug-and-play simplicity and full compatibility with standard remanufacturing processes, the upgraded chip is ideal for mass production and bulk MPS fleet maintenance. The upgraded 66S1000 toner chip is now in full stock for North American bulk orders. We will continuously update serial numbers to adapt to future Lexmark firmware upgrades.
