Device and method for testing ink box chip of printer

Abstract

The invention provides a device for testing an ink box chip of a printer, which comprises a printer control module, a chip signal transfer module, a USB (Universal Serial Bus) control module and a man-machine interaction interface, wherein the chip signal transfer module is connected with the printer control module; the chip signal transfer module is provided with a test terminal for being connected with the chip; the USB control module is connected with the printer control module; and the man-machine interaction interface is connected with the USB control module. By the USB control module, the whole testing process is controlled to be carried out in one step. Signal generating capability and signal measuring capability of the printer are adopted, so that the testing result accuracy is high. The accuracy and the operating efficiency of testing the chip are improved. The device for testing the ink box chip of the printer is reliable to use.

Description

technical field [0001] The invention relates to a chip testing device, in particular to a printer ink box chip testing device and a chip testing method using the printer ink box chip testing device. Background technique [0002] Ink-jet printer is a kind of common printing equipment, and existing ink-jet printer mostly uses detachable ink cartridge, and it is installed in the word carriage of ink-jet printer, provides ink to ink-jet printer, and ink from the nozzle on the word carriage Spray onto the recording medium, and finally form the printed pattern. The ink cartridges used in most inkjet printers are usually equipped with a printer cartridge chip for storing ink-related information, and the ink cartridge chip is generally fixed on the outer surface of the ink cartridge at a position corresponding to the probe in the printer carriage. There are generally seven or nine printer probes, and the ink cartridge chip has contacts corresponding to the number and position of th...

AI Technical Summary

Problems solved by technology

[0007] If you put the chip directly into the printer and test whether the chip is qualified through the communication between the printer and the chip, there will be some problems: when the printer communicates with the chip, the character carriage will move in the rack, and every time you change the chip, you need to Only by moving the carriage to the specified position can the chip be loaded into the carriage, which results in a cumbersome testing process and a long test time; when testing the chip, the chip is generally fixed on the ink cartridge or a specially made mold. When entering the car, the contacts of the chip can be reliably contacted and connected with the probes on the chip signal adapter board in the car. However, after the chip test is completed, the chip must be removed from the ink cartridge or the specially made mold. , the operation process is complicated, and the test efficiency is low; since the ink cartridge of the printer is equipped with a tubular ink inlet, if it is a random inspection of the product and the finished ink cartridge is loaded into the carriage, the sealant of the ink outlet of the ink cartridge will be pierced by the ink inlet , even if the chip test is qualified, the ink cartridge cannot be shipped as a qualified finished product, and the loss is relatively large

[0008] In addition, the test process of the printer is generally controlled through the control panel of the PC. In this way, not only does it need to add a computer, but also during operation, the control panel of the PC follows up the control step by step according to the position of the printer word cart, requiring operators to Constantly clicking the mouse, the operator's work is cumbersome and inefficient
