Because firmware upgrade from the original producer is beyond the our control, and can't be prevented in advance by R&D or  testing. Therefore, malfunction of compatible products arising from firmware upgrade does not fall into the scope of quality problems.

With years of experience in printer firmware production and close cooperation on the chip supply side, we have obtained the latest upgrade solutions from the chip manufacturing side. According to tests so far, the new chip works well on an updated version of HP's CF500 series printer, and will be used in subsequent production.
