The influence of inkjet printer design on printhead quality

When customers choose inkjet printers, they often pay attention to the stability of printer operation. When debugging ink dots and test printing, it is often necessary to adjust the driving value of the nozzle to obtain the most ideal printing effect.

In real operation, the operator will constantly observe when adjusting the nozzle drive value. Between the highest and lowest drive value, choose the middle value as the printer drive operation. Parameter

Number. The wider the window of the nozzle drive reference number, it proves that the better the quality of the print head, the more stable the printer.

The main factors that affect the quality of the print head are as follows:

1. Viscosity changes caused by ink temperature changes

2. Ink viscosity change caused by adding diluent or cleaning process

3. Filtering change of filter

4. Ink colloid or particle influence

5. Pressure change

< /p>

Affected by the above points, the ink point breakpoint drive more or less drifts up and down. If the drive value goes out of the effective range of the nozzle drive during the operation, the printing will be printed. Flower or

Alarm.

So an excellent quality print head must have a wide driving range, so that the inkjet printer can work effectively. Take the cij printer as an example, the nozzle of +40~-40

The driver is good sebum, and the driver is higher than 140.

Not only that, the nozzle drive value is also affected by the following factors:

1. The aging of the nozzle piezoelectric ceramics , The driving value is getting higher and higher, the effective range is getting smaller, and it needs to be replaced.

2. The quality of piezoelectric ceramics

3. The quality of piezoelectric ceramic electrodes

4. Whether the discharge coefficient of the nozzle gemstone is bad.

The above points all affect the quality of the nozzle drive value. Whether the nozzle can work stably determines the working efficiency of the printer. In addition, routine maintenance also occupies an important position. Timely and correct routine maintenance can not only extend the service life of the inkjet printer, but also maintain its work efficiency and ensure that the company Stable operation of the production line.
