In part 2, the function of the Damper and problematic points.
In part 3, the operating principle of the pump motor.
In part 4, we explained the Captop and Print head positions.
In Part 5, we explained how to replace the Captop.
For the time being, we will cover the problems and solutions that actual users are talking about.
Today, I will explain the case where the white print head inkload (pumping) does not work and how to resolve it.
I. “I think the white print head is clogged” _UV Printer Ink Supply Problem I think White is clogged
1. Problem _UV Printer Ink Supply Problem I think White is clogged
“It was working fine before the Lunar New Year holiday, and it was working fine again this morning, but now that I’ve tried it again, I’m having trouble.”
2. Check if inkload (pumping) is working properly _UV Printer Ink Supply Problem I think White is clogged
First call
“I think the white head is clogged. I did the ink load 5 times, the cleaning 5 times, and the test print with the ARTJET TEST image in white full, but the white doesn’t come out.”
“When you load (pump) the ink, does the ink come out well without air bubbles?”
“The space is narrow, so I didn’t look that far. I’ll put it away and check if the ink load (pumping) is working well. I’ll check the waste ink bottle.”
“Then, load (pump) the ink and see if it works well. I’ll call you back in 5 minutes.”
Second call
“Team leader, at first, only a few bubbles came out,,, but nothing came out.”
“Move the head carriage to the left, pour some alcohol into the captop, and inkload (pump) again. If you don’t use it for a long time, sometimes the white captop dries out and the ink doesn’t come out well when you inkload (pump) it.”
“What is the captop? Oh,,, how do I move the head carriage to the left?”
“If you press the left arrow button, the head carriage goes to the left, and when it goes a certain distance, press it again. Then it stops. And where the print head carriage was originally, the black square with the border is the captop. Pour enough alcohol into the white captop.”
“It seems like this is the first time I’ve pressed the left arrow.. lol, I’ll give it a try.”
Third call
“Representative, is the ink loading (pumping)?”
“It seems like alcohol comes out at first, but nothing comes out after that. Is it possible that the white print head is clogged?”
“The print head is probably not clogged, but it’s probably because the ink isn’t being supplied yet. Please repeat the same process a few more times.”
Last message. All is OK.
II. Causes and Solutions to the Problem _UV Printer Ink Supply Problem I think White is clogged
1. Why the head is not blocked _UV Printer Ink Supply Problem I think White is clogged
Looking at the nozzle pattern, white doesn’t come out completely, but since there are faint patterns, it’s not that the print head is clogged.
2. Number of cases where the head gets blocked _UV Printer Ink Supply Problem I think White is clogged
The first case of head nozzle clogging is print head nozzle clogging caused by UV light. If you don’t know the difference between a head and a nozzle, click here.
During printing, the UV ink under the print head is exposed to UV light, and when the light accumulates and exceeds a critical point, the ink begins to harden.
When the UV ink begins to harden, a chain reaction occurs, starting from the nozzle exposed to the light and hardening all the way to the ink inside the nozzle.
A clogged nozzle does not produce a nozzle pattern itself.
The second cause is high temperature.
Ink used in industrial print heads such as Konica and Dimatix has a viscosity of 20cp at room temperature. 20cp is a viscosity that cannot be jetted by an inkjet print head.
The head is heated to between 40 and 50 degrees with a heating device inside, and the ink is jetted while the viscosity is lowered to 10cp.
During the holiday, if the ink is not jetted and heat is continuously applied to the head, the ink remaining at the tip of the nozzle hardens due to the heat.
If it becomes clogged like this, even if you do inkload (pumping) and cleaning, the pattern will not come out from the clogged nozzle.
In this way, the print head can block the nozzle with UV light and heat, and once blocked, no ink will come out of the blocked nozzle.
In particular, when printing on tall materials, the UV reflection angle increases, so more UV light reaches the head, and the entire head can be blocked in an instant.
When printing on tall materials, you should place a material of similar height next to the printing material to prevent the UV reflection angle from increasing.
In fact, in May 2020, an accident occurred in which three heads were blocked while continuously printing 70mm materials on equipment installed.
3. ARTJET UV Printer _UV Printer Ink Supply Problem I think White is clogged
The Epson XP600 print head does not have an internal heater, so it is not a head clogging due to heat,
and the print head is sealed with a captop, so it is not a natural curing due to external light,
and as the printer was upgraded, a lamp reflection angle was added,
Even, this customer did not print on high materials,
so it was not a print head nozzle clogging.
4. The cause is _UV Printer Ink Supply Problem I think White is clogged
The print head sealed with a captop was exposed to the air during the holiday when the seal was broken, so the captop surface hardened to white and blocked all the tiny gaps. I guess so.
Since the surface was blocked, ink did not come out even when ink was loaded (pumped).
He poured alcohol on the captop and tried it once, but it didn’t work.
“At first, alcohol seems to come out, but after that, nothing comes out. Could it be that the white print head is clogged?”
When he poured alcohol once, the dried captop was solved, but
during the previous ink load (pumping) 5 times and print head cleaning 5 times, all the lines from captop to the waste ink tank were filled with only air instead of liquid (ink),
and ink load (pumping) doesn’t work well when there is only air in the line, and since it continuously flows liquid while liquid is in it,
even if he poured alcohol on the captop once, liquid didn’t fill all the lines, so it seems that the ink wasn’t extracted well.
He did the same thing several times and it was solved.
There are consumables that are the most basic of the basics when it comes to inkload, that is, pumping.
III. This is how ARTJET supports our customers.
