To determine whether the printer chip is original by printing a test page, you can start from the following aspects:

1. Print quality:

• Text and image clarity: Original chips usually ensure that the text on the printed test page is clear and sharp, with complete strokes, without blur, missing strokes, or broken strokes. The image has rich details, natural grayscale transitions, and high color saturation and accuracy. If the text edges of the printed test page are blurred, the image has noise, and the color is distorted, the chip may not be original, or the chip has quality problems that affect the print quality.

• Print integrity: Original chips can ensure that the test page is printed completely, and all content on the page can be printed correctly without omissions or partial missing. For example, the lines of the table on the test page are complete, and the graphics are not incomplete. If the printed content is incomplete, there may be problems with the communication or data transmission between the chip and the printer, which may mean that the chip is not original or the chip is not compatible with the printer.

2. Information display:

• Accuracy of chip information: The test page of some printers will display relevant information about the printer and chip, such as the chip model, version, serial number, etc. The information displayed by the original chip should match the model of the printer and the information provided by the official. If the chip information displayed on the test page does not correspond to the printer, or the information is incomplete or inaccurate, then it is likely that the chip is not original.

• Print count information: Some printer chips will record count information such as the number of pages printed, and this data may be displayed on the test page. The count information of the original chip is usually accurate and reliable, and consistent with the actual use of the printer. If the print count on the test page is abnormal, such as the value is too high or too low, and it is very different from the actual print volume, then the chip may have a problem or is not original.

3. Print speed:

• Printing smoothness: The original chip can support the printer to print the test page at a normal speed, and there will be no jamming, pauses or delays during the printing process. If the printer prints significantly slower when printing the test page, or there are frequent pauses and waits during printing, it may be that the chip performance is poor, or there is a problem with the chip and the printer, which may also indicate that the chip is not original.

• Continuous printing capability: Try to print multiple test pages continuously. The original chip can stably support the printer to print continuously without any failure or abnormality. If the printer reports errors, paper jams, or printing interruptions during continuous printing, the quality and compatibility of the chip may be questionable, and it may not be an original chip.
