Solution to printing failure of pure cotton direct jet digital printing machine
Cotton direct injection numberCauses and solutions for failures in the printing process of code printing machines. Any kind of machine will have problems of this kind during use, and digital printing machines are no exception. In general, several problems of pure cotton direct-injection digital printing machines are common. Therefore, it is necessary to understand the reasons and solutions to solve the problems in a timely manner without affecting the progress of the work. Causes and solutions of several common problems of towel digital printing machine
How to solve the printing failure of the cotton direct-injection digital printing machine?
1. There are obvious broken lines in the printed image. Causes: broken needles in the ink head. As long as one ink hole of the pressure point nozzle is blocked, it may cause broken lines in the image. If multiple nozzle holes are blocked, the broken lines will become serious. Solution: Clean the ink head and remove the clogged nozzle. a. Impurities in the pipe b. Impurities in the ink sac. Clean the ink sac pipe c. The ink is contaminated d. There is a problem with the ink quality. Replace the ink. e. Environmental problems, the temperature is too low Install air conditioning to improve the working environment temperature f. The print head is in poor condition and replace the print head. g. The surface of the print head is too dirty and fluffy. Clean the surface of the print head. h. Scraper, the ink stack is too dirty. Clean the blade, ink sac, ink stack K. Ink sac There is an air duct to draw the air out of the ink bag
two.Garment printing machineOverprinted dark streaks in the printed image
2. The paper feeder is too tightly jammed, resulting in poor paper feeding, causing great resistance to the Y-axis stepping motor and failing to reach the standard step value. 3. There are differences in the stepping amount when feeding paper of different thickness. Solution: 1. To calibrate the print head, please contact professional technicians. 2. Use manual paper feeding to reduce resistance. 4. Adjust the paper step setting CALIBRATION menu in the machine to increase or decrease the step value. a. The print head is disconnected and clean the print head. b. Printing ink is not enough, increase the ink output. c. The paper feeder is too tight, relax the paper feeder.
three.Treadmill printing machineDuring the printing process, the ink cart stopped for several seconds at both ends of the image. Reasons: 1. The computing speed of the computer cannot keep up with the transmission speed and printing speed. 2. The printing port is used for transmission, and the transmission speed can not keep up with the printing speed when large pictures. Solution: 1. To replace a faster computer, a computer with Pentium 4 1.7G or higher is generally required. 3. Using 100M network cable for transmission, the network transmission speed is faster than the printing port transmission speed. a. The machine crashes and the machine shell is grounded. b. The computer crashes and restarts the computer.
