In the process of procuring compatible toner cartridges, sample testing is a crucial step in determining whether a product is worth mass production and long-term cooperation. An effective sample test should not only focus on whether it "prints," but also on the following core indicators:

1. Print Clarity and Density: Observe whether the text edges are clear, whether the image is uniform, and whether there are any blurry or grayish phenomena. Stable blackness indicates good matching between the toner and the developing system.

2. Page Yield Performance: Whether the number of pages printed in the sample is close to the nominal value is an important indicator of the toner cartridge's cost-effectiveness. Testing should be conducted continuously under normal coverage conditions, not just printing a small number of pages.

3. Stability and Consistency: Pay close attention to whether there are issues such as background graying, streaks, toner leakage, or significant differences in print quality during continuous printing. Stability directly affects the performance of the bulk order.

4. Printer Recognition and Compatibility: Confirm whether the toner cartridge can be correctly recognized by the printer, without error messages or abnormal prompts, and whether installation and removal are smooth.

5. Structure and Sealing Inspect the toner cartridge casing, interfaces, and seals.

Check for toner leakage after slight shaking, as this is crucial for transportation and long-term use.

Sample testing is not only about performance, but also about verifying the factory's manufacturing capabilities and quality control level.
