1, naked eye observation.
1.1 Please open the seal, carefully observe whether there is color supplies;
1.2 carefully observed, and now there is a small bubble inside;
1.3 supplies if it is transparent, please carefully observe the color of the material is uniform; under normal circumstances uneven color, indicating that supplies in the production of a partial change occurred.
1.4 wire whether there are black or other color spots.
Visual observation is the most basic, master the basis of Xiaobian recommend you learn advanced skills to understand the accuracy of the reasons even after the same 3D printer can also greatly improve the accuracy of the problem
2, the accuracy.
2.1 feel the test accuracy. Opened 1-2 meters long brother dr730 toner, with the thumb and index finger gently grip supplies, and then slowly to pull supplies. If the consumables are uneven thickness or the surface of the consumables is not smooth, the feel is very easy to perceive.
2.2 Instrument test. Using a numeric display of the vernier caliper to measure whether it is within the tolerances of the control.
2.3 Measurement method. In the length of 1-2 meters measured, the test wire diameter tolerance is uniform; at each test point, the rotation of a week to measure the range of 3-4 circumference, the main measurement of wire is "round", that is: whether the wire diameter control effective The
3, observe the quality of printer supplies of dell toner cartridge
3.1 observe the substrate printing line uniformity. The general printer in the printing began to do the substrate, observe the nozzle on the substrate uniformity. Under normal circumstances, relatively uniform, supplies precision control in the range.
3.2 listen to sound judgments. If the consumable in normal operation, the gear feeding device, if the printer supplies are not uniform, then it will issue a "Hang Hang" sound.
3.3 Print to determine the quality of supplies. Observe the uniformity of the internal structure of the consumables in print. Whether there are bubbles, spots and other issues.
3.4 Viscosity judgment. Consumables must be viscous during printing, otherwise the print will crack or disengage. Taking into account the many types of supplies, a variety of printer substrates are different, the material will be incompatible phenomenon. To ensure smooth printing, it is best to apply some glue on the substrate. Otherwise, due to the printer and the model in the printing process of friction, collision caused by print interrupt.jpg)
