What should I do if the small character inkjet printer reports a charging failure?-

The small character inkjet printer needs to charge the ink when it is running. After charging, the ink droplets are charged and deflected under the action of a high-voltage deflection plate, and the required inkjet information is generated through the movement of the item. In order to ensure that each ink droplet is charged, the small character cij printer also has a component that detects charging, called phase detection. If the ink droplet is not properly charged, it will report the detection failure of the charging ink point, which is what we often call small character jetting. Coder charging failure.

There are three cases of charging ink dot detection failure:

1. Poor splitting of ink dots, unqualified modulation voltage, abnormal ink viscosity, insufficient pressure, or the crystal shock rod may be damaged, but the probability of crystal shock rod damage is relatively small.

Second, the ink deteriorates, the ink expires, the water content in the ink affects the charging or the ink has precipitation.

3. There is a problem with the charging circuit board and the phase detection circuit board, the charging slot is dirty, causing the ink to stick; it is also possible that the charging slot is damaged.

After understanding the situation of charging ink dot detection failure in detail, the solution will be easily solved. Here is the workaround:

1. Check the split of the ink dots, if the split is not good, adjust the modulation voltage and analyze the changes until it is suitable.

2. Check the cleanliness of the charging slot of the small character inkjet printer. Dust or other dirty things on the charging slot must be cleaned and dried.

3. Check whether the ink has expired, and analyze whether the set value of the ink viscosity matches the current value to determine whether the viscosity of the ink is appropriate. The most direct and fastest way is to replace the new ink.

The above is the little knowledge about the charging fault of the small character inkjet printer that the technical engineer has compiled for you. For more information about inkjet printing, welcome to inquire about the technology!
