2022-10-20, HP released the new firmware for CF500 series, firmware No. 20221010 20221018. This caused compatible chips showing ERRO on machines with new firmware, see the ERRO bellow. Similar printers for Canon not affected.


Xinying Technology solved the problem in just 4 hours. We tested and our new chips shown normal on machines with new firmware, see the test screen shot as bellow:

We declare that our new chips are in supply, and we will keep our eye on firmware upgrade. We also suggest all printer users cancel the firmware upgrade function in your machine.
