Today, I will explain the problem and solution of how to fix it, which was difficult to keep nozzles in white channels 1, 2, 3, and 4 aldsive, even though pumping and cleaning were both successful.

I. Problem _UV Printer When to Replace the Damper

1. 10 month old demo equipment _UV Printer When to Replace the Damper    

Color, Varnish almost never need cleaning. The nozzle condition is almost perfect even without cleaning.

However, after 3~4 months of installation, the white nozzle condition started to take time to recover the nozzle,

and since two months ago, before operating the printer, too much ink has been used to fix the white nozzle condition through pumping cleaning, and it has taken quite a while.

 

2. It’s okay once it starts coming out,,, _UV Printer When to Replace the Damper

One peculiarity is that once the condition was set in the morning, the nozzle condition was easily restored by cleaning from then on.

However, the next morning, I had to struggle with pumping and cleaning again to restore the nozzle condition.

Since it was a demo device, I didn’t use it often, and every time I used it, I replaced parts or took action on suspicious parts.

After the action, it improved little by little, but it wasn’t like when I first installed it.

 

‘Why isn’t the white nozzle condition restored with one or two cleanings like when I first installed it?’\

 

After two months of all measures, I found the answer!!

II. Measures taken _UV Printer When to Replace the Damper

1. Positioning the Head and Captop _Printer Troubleshot Damper replacement time    

Of course, pumping and cleaning went well,

When doing a nozzle test, White channels 5 and 6 were recovered almost immediately, but nozzle recovery took some time in channels 1, 2, 3, and 4.

In particular, channels 1 and 2, and among them, channel 1 took a bit more time.

Because of this, I made the print head and captop position more perfect so that both cleaning and pumping would work well,

but when I do cleaning again the next day, there was no improvement.

Since I did a lot of cleaning tests when positioning, it seemed like it had improved with a lot of cleaning.

 

I am absolutely not saying that positioning the print head and captop does not help with white nozzle recovery.
This part should be done well as a basic rule, and it was not the cause of the long white nozzle recovery time in our demo equipment.

 

If pumping does not work even after checking everything, refer to the link below to position the print head and captop.

2. Capping station horizontal adjustment _UV Printer When to Replace the Damper   

 

Pumping and cleaning are also very good, but…

‘Why is it difficult to restore the nozzle of channel 1234, especially the end channel 1?’

 

I had a lot of thoughts.

‘I wonder if when the captop is sealed to the bottom of the print head, it is tilted to one side and the ink suction power from the end is weak?’

I bought a small level and leveled it, which reduced the time it took to recover the white nozzle a lot.

However,, even so, it required several cleanings,,, and it wasn’t perfect.

Please refer to the following for how to adjust the level of the capping station.

How to level the capping station

Do not change the height of the white part, but adjust other parts to level it,

More important than the level is that the left and right gaps in the capping state should be the same.

 

3. Other various measures _UV Printer When to Replace the Damper

White channels 5 and 6 always came out well, but among them 1, 2, 3, and 4, 1 and 2, especially channel 1 nozzle recovery was difficult.

‘When pumping, ink comes out only from the damper where ink comes out, but not from channel 1 and 2 dampers?’

The pump tube only made a humming sound during the first cleaning and did not turn, but it started turning from the second time, so at first I only adjusted the cleaning time,

How to adjust the pump time during cleaning

To reduce variables, I replaced not only the pump tube but also the Captop.

After replacing, the cleaning operation worked well, so there was an improvement.

However, it was still not as good as when it was first installed.

 

III. The last one _UV Printer When to Replace the Damper

1. White nozzle pattern _UV Printer When to Replace the Damper   

Channels 5 and 6 are clean, 4 is easily recovered, 1, 2, and 3 take a little longer,

Nozzles of channels 1, 2, and 3 did not improve even after cleaning several times and printing the TEST image.

When looking at the nozzle test patterns of channels 1, 2, and 3, they felt thicker and rougher than 4, 5, and 6.

 

‘Maybe the damper is involved in ink supply, but since it is a filter, the mesh that filters out ink residue and bubbles has reached the end of its life?’

‘Varnish and color have small pigments so they do not have a big effect, but white has large pigments so the mesh life may be short,’

 

There are two White main bottles,

• White 1 bottle supplies ink to channels 1,2,3,4
• White 2 bottle supplies ink to channels 5,6

I decided to replace Dampers 1, 2, 3, and 4 connected to the White 1 main bottle all at once. After replacing them, the nozzle condition improved immediately with one or two cleanings.

Up until now, whenever I took action, it got better at the time, so I thought, ‘Maybe it’s a temporary phenomenon?’ and conducted the test again the next day.

Even then, the nozzles were all restored with one or two cleanings.

‘But I’ll have to wait until the weekend to know for sure.’

A few days later, on Monday, after pumping, I cleaned them once or twice, and the problematic channels 1,2,3,4, and especially channel 1, improved quickly.

 

2. Damper Function _UV Printer When to Replace the Damper  

I vaguely know it, but when I searched on Google,

 

[The ink dampers are used to supply ink to the printhead and also filter the ink.
The ink tank is used to store ink. The function of the ink damper is to filter the stored ink twice, and then supply the ink to the printhead to realize the function of transporting the ink in the middle]

 

The damper maintains the appropriate level when supplying ink with natural pressure so that the level can be jetted from the print head,

Second, it filters out ink residue or fine air bubbles.

That is, it seems that white ink residue remained in the damper filter and nozzle recovery was not easy.

3. From replacing consumables _UV Printer When to Replace the Damper  

If the pumping and cleaning are done but it does not work smoothly and the nozzle is not easy to recover,

First, the Captop and pump tube should be replaced, and if the nozzle is still not easy to recover, it would be a good idea to replace the Damper and then check the problem.

IV. 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.
