How to Deal with the Poor Fluency of Sublimation Ink on Inkjet Printer

remove the air bubbleNowadays, many inkjet printers use the Epson fifth-generation print heads. At the same time, piezoelectric inkjet printers also have many problems. If the fluency of inkjet printers after ink refilling is poor, short-term conditions may occur after printing for tens of centimeters. Today, I would like to share with you an analysis of the reasons and solutions for the poor fluency of sublimation ink.

Now the sublimation ink used in piezoelectric inkjet printers is water-based dye ink, which generates air bubbles during the ink refill process. Because the ink pump will draw the ink together with the air bubbles during the ink pumping process. You can start to do the head detection. When you see the ink out of the whole, you begin to
the air bubble in inkprint pictures. At this time, the bubbles in the ink are not completely discharged from the ink, there will be some very small bubbles in the ink because of the pressure. Air bubbles accumulate at the nozzle as the ink is ejected during printing. A large number of small bubbles form a large bubble, blocking the nozzle to form a gas plug. This causes a situation in which the ink will break after printing for a while during printing. This situation is likely to occur when just changed the ink or when install a new machine.

The solution: Fill the ink to the ink tank. Let the ink at the nozzle print out and leave the machine for 20-30 minutes before printing. So that the smallest bubbles in the ink can be removed to minimize the possibility of gas blocking.

1. Inspection method:
remove the air bubbleAfter injecting 25ml to 30ml of ink into the nozzle, suck the air in the pipe to install the sprinkler. Then place the sprinkler higher than the trolley for three secondsand put it upside down. There will be air bubbles rising inside the sprinkler. If the air bubble rise and stops slowly, it is normal. If it rises and does not stop, it can be judged to be the leakage of the installation.

2. Leakage phenomenon:
The bubble does not go inside the nozzle when spraying the picture; the bubble flows back; the nozzle holes accumulate ink seriously; the contact belt is stained with ink; the ink is broken when the picture is sprayed.

3. The solution:
The above phenomenon is that the mounting hole leaks. It may be too much force during installation. Then the installation hole of the nozzle is broken. We can use the middle hole of the bicycle inner tube to cover the nozzle mounting holethen lighten the ink needle.

Is UV Ink Environmentally Friendly& How to Minimize the Harm

UV ink is more environmentally friendly than traditional printing pigment (solid, liquid and powdery). Especially when printed on the surface of the material for up to UV ink12 hours, it is almost odorless and can be directly exposed by the skin. But it still contains a small amount of toxicity. After all, the composition of the ink contains chemicals.

We need to understand that the more cheaper the inferior UV ink is, the more toxic it is. Compared to the imported high-end UV ink, the toxic damage can reach 10 times or even higher.

The harm of UV ink is mainly  in two aspects:
1.The corrosiveness of the ink:
A few people is sensitive to the skin. After contact with the UV ink, rashes and allergies may occur. It is necessary to wash and rub the ointment in time. If you accidentally splash into your eyes, flush it with clean water immediately.

2. The odor of ink is irritating:
Some people, especially those with sensitive rhinitis and respiratory tract inflammation, are easily irritated and cause discomfort.

The solutions:
1.Keep the indoor ventilationsmooth. Do not install the UV printer in a closed and ventilated place;
2. If conditions permit, you can isolate the UV printer operating room separately;
3.If there is no separate conditions, choose to wear masks to filter;
4.Technicians should exercise more daily, eat more fruits, pay attention to diet and so on. This will improve their immunity.

Whether it is the operator or the user itself, there is no need to worry too much about the UV ink. This is within the acceptable range of the human body and there are few cases of discomfort. If you are a woman during pregnancy, we recommend that you do not operate the device.

5 Common Malfunctions and Solutions of Ink Cartridges

The ink cartridge is an ink-storage accessory in an inkjet printer device. If the
cartridge fails, the device will not work properly. After sorting, there are several
kinds of common ink cartridge malfunctions. If you encounter the similar
ink cartridgesituations below, you can refer to the following methods to solve them.

1.Leaking ink: When a new ink cartridge is on the machine, the ink leaks out of the ink jet hole. It will pollute the inkjet printerand easy to burn the main board. This situation is the quality of the cartridge case and we should replace the ink cartridge immediately.

2. Long time transport and storage in high temperature or low temperature environment is one of the main reasons for ink cartridges to spoil or not to ink out. It is necessary to use it at room temperature for a period of time before using. Otherwise, it may not be able to spray ink.

3. The picture is rough, not delicate or smooth.The reasons below:
1) The output medium is poor and the ink is easy to penetrate.
2) The set resolution is low. It reduces the print quality while increasing the speed.
3) Disconnect: After confirming by nozzle inspection, we can clean once or twice to eliminate it.

ink leakage

4. After the new ink cartridge is installed, it displays no ink or print pages. The reasons below:
1) The ink cartridge is not installed properly or the cartridge case is not returned to the sensor cartridge. It is necessary to reinstall or manually reset the shrapnel.
2) The metal sheet in the inkjet printer’s nozzle is aging or loose, causing poor contact. We recommend to send it to the maintenance station for repair.
3) The ink cartridge is not changed according to the prescribed procedures. You need to replace the ink cartridges according to the prescribed procedures.
4) If we still can’t resolve this situation, it is very likely that the printer’s electronic memory is faulty. You need to delete the printer driver, reinstall the driver and remove the cartridge again to reinstall the cartridge as described above.

5. The nozzle blockage is mainly due to the fact that doesn’t return to the protective cover or load the new ink cartridge in time. It results in exposing the print head to
the air for too long. The ink remaining in it is blocked due to air drying. We can improve this situation by the cleaning function that clean the inkjet printer itself. If the blockage is serious, it can only professionally clean it or scrap.
