From late April to early May 2025, major printer manufacturers such as HP, Ricoh, Xerox, Brother, and Kyocera released firmware updates.

Following extensive testing, our engineers confirmed that Zhono compatible chips used in these printers and copiers remain unaffected by the OEM firmware upgrades. The chips function correctly  with both previous and current models of the devices. Zhono chips continue to uphold their reliable quality.

The chart below highlights the successful test results for  Zhono chips across various brands and models.

No matter the brand or model of your printer, Zhono provides highly stable chips to help you easily handle firmware upgrades.
