The ink circuit system of the digital printing machine includes ink bottle, ink tube, negative pressure system, ink circulation, ink sac, nozzle, etc. Most of the failures encountered by the cotton printing machine are concentrated in the ink circuit system, so do the ink circuit well. System maintenance is the top priority. So how to maintain the ink system of the cotton inkjet digital printing machine? 1. A single ink cartridge cannot be completely empty. When the ink quantity indicator on the control panel of the cotton digital printing machine is on, please pay attention to the ink capacity, and replace the new ink cartridge immediately with a maximum of 2 meters to prevent air from entering the ink tube. 2. When a certain color cannot be printed at all, please check whether there is ink in the ink cartridge or the nozzle of the cotton printing machine is blocked. 3. When the nozzle of the cotton spray digital printing machine is clogged, please clean the nozzle immediately. The specific operation can use the 'direct nozzle cleaning' function in GMG dotproof. If you can’t clean it after cleaning two or three times, please use the “direct powerful cleaning” function. When cleaning with this method, when there is an English prompt on the control panel of the cotton printing machine, please turn on the ink sticks that fix the ink cartridges on both sides, and wait for the cotton digital printing machine. When there is an English prompt on the panel for a while, please knock down the ink stick and repeat this two or three times. After cleaning, check the result with the function of 'Print Nozzle Pattern'. 4. Cleaning method when the ink tube has bubbles (use this method with caution, don't use it when it is not necessary): The bubble in the ink tube is caused by the ink cartridge being printed too empty and entering the air. Enter the engineering menu of the cotton printing machine and put the ink tube in the ink tube. The ink is completely discharged. During operation, each ink cartridge must have at least 50% ink. Clear the waste ink tank and turn off the cotton-jet digital printing machine.
