Before you buy this product, you need to pay attention to:

NOTE: The printer must be disconnected from the power source before the print head is installed, otherwise it has the risk of causing the print head circuit board to burn out.

1. When the print head is shipped, a protective liquid will be applied to the print head. Before using it for the first time, wipe the print head before installing it.Just wipe the copper sheet gently, wipe it clean with soft paper, don't wipe it with cleaning fluid or eraser.

2. During the regeneration process of the print head, the ink will be cleaned and the protection liquid will be injected. If there is no protective liquid, the print head cannot print because the pipeline channel is dry.If the print head can be detected, but the colors are uneven or blurred, you can continue printing with ink. Print a few more sheets of paper and wait for the excess protection fluid to run out, then you can print normally

3. If the printing effect is not clear, press the machine cleaning button to clean (the print head must be cleaned only when the ink cartridge is sufficient, or it will burn out easily).

4. You don't need to clean the print head with cleaning fluid, you can clean the print head directly on the machine. If you clean the print head with the cleaning fluid(or water) and do not drop the protective fluid, the print head will be completely blocked, and it will be useless.

Before you install this product, you need to pay attention to:

1.After receiving the print head, if you use a needle tube to inject water to check the nozzle or see if it is blocked, this is a very redundant and dangerous behavior.If the printing effect is not clear, press the machine cleaning button (the pFirst of all, once the print head enters the water, if the water is not dry, it is powered on. The main board will be burned out, and the print head will be burnt out. Secondly, the print heads sold in our shop have been strictly tested and filled with protective liquid.If you use a needle to inject water into the print head, it will not only wash away the protective liquid in the head, but also easily cause air blockage in the print head, resulting in no ink.

2.Be careful when installing the print head, be sure to cut off the power first, and install it in place.

3.When connecting the plug cable, do not have ink on it, and make sure that it is in good contact with the socket.

4.The steel shaft should also be clean and smooth. You can use a paper towel to stick some lubricating oil to wipe it. Do not directly add oil to the shaft. The excess oil will flow to the print head and cause damage.

5.After the machinery and circuit are all correct, check the water circuit. Firstly, check whether the ink volume in the ink cartridge is sufficient; secondly, check whether the small cleaning blade and the ink suction pump are dirty.

6.There will be air in the newly installed print head, so it will not print normally immediately. The printer can only produce perfect results after the air in the head is completely discharged.You can use the machine's own cleaning function for intermittent cleaning(Clean 2 times each time, and then 2 times after 30 minutes) Repeated over-cleaning will cause ink accumulation in the cleaning pump, which will not only cause color mixing, ink leakage, and waste ink.Finally, you can print more pictures to let the print head exhaust air during work.

Remarque:

1.Dans l'impression entrée, veuillez éteindre l'imprimante, sinon la puce de la carte mère sera brûlée.

Après avoir chargé la tête d'impression, veuillez ne pas installer de ruban au-dessus de 10 pièces de document A4,

afin que la nouvelle aiguille ait un processus de rodage, puis placez le ruban. J'espère que vous pouvez être prudent.

2.Si la tête d'impression d'origine était cassée et surtout une fuite d'encre, la carte mère a peut-être brûlé,

veuillez donc résoudre le problème de la carte mère avant de remplacer la tête d'impression. En plus,

le fil de fusée F1, F2 de la carte mère ne peut être remplacé que par la fusée d'origine qui a la même valeur actuelle et le même modèle.

Si vous remplacez une fusée dont la valeur actuelle est plus élevée et un modèle différent, la tête d'impression et la carte mère peuvent être cassées.

3.La tête d'impression nécessite beaucoup d'attention, il est facile de provoquer des dommages causés par l'homme si un non-professionnel remplace la tête d'impression à l'aveugle.

Il existe une réglementation selon laquelle la tête d'impression n'est pas garantie, et elle est délicate et coûteuse.

veuillez ne pas mettre en service la machine et veuillez la traiter avec prudence.

4.Si vous n'êtes pas familier avec la machine, il est recommandé d'envoyer la tête d'impression à un centre de réparation.

ou trouver des professionnels pour remplacer la buse, afin d'éviter des pertes et des problèmes inutiles.
