Printhead inkjet principle

Up until last time, we have summarized 24 UV printer ink supply problems and solutions.

This is a summary of all the issues that have occurred over the past 5 years. If you have a printer that uses the damper method, you can solve most problems by just looking at the link below.

Ink supply issue and solution summary

 

Now, I’m organizing the problems and symptoms related to the UV Printer head.

Before dealing with the actual problems and solutions, there are too many misconceptions about the head, so I’ll explain the basics first.

1.Does the head have a lifespan? Is a head warranty available?
2. “In what cases does the head free warranty apply?’
3. “They say it’s the same head but 2400 dpi?” Summary of the concept of printing resolution
4. “I don’t know what print head specs mean” Just by reading this, you will have the same level of knowledge as a printer distributor.
5. “Look at the actual head brochure and explain the important points to consider among the specifications and their meanings.”

 

Today I’m going to explain how the print head sprays ink.

 

I. Ink jetting method  _Printhead inkjet principle

1. Shear Wall _Printhead inkjet principle

​If you look at the bottom of the print head, you will see something like a long line.

If you enlarge that line, you will see that it consists of many holes, as shown in the picture on the right.

The inside of the hole is a narrow passage as shown in the picture below,

When the narrow passage opens, ink comes in, and when it narrows inward, ink is jetted out of the nozzle.

When this process is repeated, ink is jetted out of the head.

The walls that form countless holes are called nozzles, and the nozzles expand and narrow when they receive electricity from an electronic signal.

The current method of jetting ink by widening and narrowing the passageway is

mainly used in SII (Seiko), KM (Konica Minolta), and Toshiba heads.

Head manufacturers call this method Shear Wall.

 

2. Bend method_Printhead inkjet principle

If you look at the picture, you can see the principle of ink jetting for each head.

Basically,

• Ink is filled at the nozzle tip,
• and when voltage is applied, the electrodes bend by the voltage force,
• and when they bend, ink is jetted out.

 

II. Things to know when choosing a head _Printhead inkjet principle

1. Increase production speed by increasing the head? _Printhead inkjet principle

Company has developed equipment that increases 1 x CMYK to 2 x CMYK to increase speed,

but it is not easy to create 1 x CMYK print quality with 2 x CMYK.

• It is not easy to align the heads exactly in a straight line,
• and it is not easy to offset the nozzle gap at the connection point of the two heads by the nozzle gap,
• and sometimes the first and last nozzles isn’t straight, so 1 x CMYK quality is not achieved.

It is good to know in advance that doubling the speed by increasing the heads and implementing the same quality is not an easy challenge.

2. Film and Ceramic _Printhead inkjet principle

Heads with film-based bases and heads with ceramic bases.

The film-based nozzle can be scratched, and scratched nozzles can have poor straightness.

On the other hand, ceramic nozzles are not scratched even by minor scratches,

but the ceramic base of the head can break if it receives a strong impact.

 

3. Cheaper than expensive _Printhead inkjet principle

If possible, it is better to choose a less durable but cheaper head than a durable and expensive head.

Instead of replacing the head due to its lifespan, you will replace the head more often due to the following reasons:

• Due to poor head maintenance,
• Due to some accidents such as head crash or UV curing,
• Due to some nozzles being fired diagonally or blocked,

Since inkjets can produce good quality just by replacing the head, it is better to choose a head with a cheaper price if possible.

 

III. This is how ARTJET supports our customers.

One thing I feel while selling and maintaining ARTJET UV Printers for 5 years is that the next most important thing after product stability is Troubleshooting DATA.

All products have problems, whether they are actual equipment problems or consumer errors, and product stability is how easily and quickly you solve those problems.

We are organizing all the troubleshooting DATA as follows.
