AI Technical Summary
The gas pressure control devices of existing inkjet printers are difficult to check frequently when maintaining a negative pressure state, resulting in decreased production efficiency and increased costs. Furthermore, existing testing methods cannot accurately assess faults without stopping printing, affecting printing precision and equipment operation.
A negative pressure test circuit is introduced into the inkjet printer. The negative pressure generation part is tested through the pressure control module without interrupting the printing process. This includes the negative pressure generation part, the positive pressure generation part, and the negative pressure test circuit. The negative pressure is measured and compared when positive pressure is applied using the negative pressure test circuit.
This technology enables frequent testing of the negative pressure of the gas pressure control device during normal operation of the inkjet printer, avoiding interruptions and increased costs due to malfunctions, and improving production efficiency and equipment reliability.
