High-quality compatible toner cartridges are not simply "assembled and ready to ship."

1. Appearance and Structural Inspection: The first step is an appearance and structural inspection to ensure the casing is intact, components fit tightly, and there is no toner leakage or abnormal noise.

The ACO toner cartridge factory employs a multi-stage quality control process, with an experienced quality control team inspecting each product to ensure it is in perfect condition before leaving the factory.

2. Print Quality Testing: Printing performance is tested using the STMC international standard, checking print density, clarity, background grayscale, and page yield.

Each batch of ACO compatible toner cartridges undergoes random sampling for printing to ensure consistent image quality and clear text.

3. Printer Compatibility Verification: Compatibility testing goes beyond simple installation and operation; it involves comprehensive verification under multiple brands and printer models.

ACO toner cartridges undergo continuous printing tests on mainstream printer models such as HP and Canon to test chip recognition rate, mechanical fit, and long-term stability.

4. Environmental and Lifespan Testing: Simulated transportation and long-term use environments are conducted under high temperature, low temperature, and high humidity conditions.

ACO ensures its toner cartridges maintain stable performance under various climate conditions.

From appearance to printing performance, a good toner cartridge must undergo comprehensive testing throughout the entire process.

We firmly believe that good products speak for themselves through their quality.

Choosing ACO means choosing a high-quality toner cartridge where every single one undergoes rigorous verification. ACO welcomes you to visit our factory at any time.
