Buyers note:

1.The head of the nozzle is very fragile and must not be bumped. It must be protected. 

  Its surface layer is a piece of aluminum, and the inner layer is coated with a crystal oscillator and a very small ink tube.

 When it touches, it will be concave, deformed, or even broken, so the nozzle will be scrapped.

2. Be careful when installing the nozzle. Always power off and put it in place. 

   After loading, gently push the car to move left and right to check whether it is smooth or not.

   It is good to electrify, because if the head is not in place, the car will easily break the head when it moves, and the hand has the feeling, the freely       retractable, and the controllability is strong;

3. When connecting the plug cable, do not bring the ink, and make sure that it is in good contact with the socket and does not touch the foot. 

   Otherwise, the nozzle will be short-circuited and burnt.

4. The steel shaft should also be clean and smooth. It can be wiped with a paper towel and glued. 

   Do not directly add oil to the shaft. Excess oil will flow to the nozzle and cause damage.

5. After the machinery and circuit are correct, it is necessary to check the waterway. 

   First, look at the insufficient amount of water in the ink cartridge. 

   Secondly, check whether the small cleaning blade and the ink suction pump are dirty.

6. There will be air inside the nozzle that has just been installed, so it will not print properly immediately. 

   Only when the air in the head is completely discharged can the line be normal; 

   firstly, it can be washed intermittently (only 2 times at a time, then 30 minutes) ,

   after cleaning 2 times and repeatedly cleaning over and over again, 

   it will cause the cleaning pump to accumulate ink, which will not only make the printer mix and color, but also leak ink,waste ink; 

   secondly, you can print more pictures to let the nozzle discharge air in the work; 

   again, if the machine has led out the waste ink tube, you can first power off, 

   then use a syringe to cover the rubber tube to evacuate the ink tube until Take out 3-5ml of ink, 

   then turn it on again, and clean it once with the machine. 

   This is equivalent to artificially pumping out the air in the head. 

   The side effect is that it is easy to cause the cleaning pump to stack ink.
