Large Format Digital Printer Ink Tube Maintenance Recommendations

When we use large format digital printers, we will inevitably encounter various failure problems. Many users do not pay attention to maintenance when using the machine, which often causes the printer to be inoperable, which delays time and wastes money. If the ink tube of the printer fails, the machine will not work. How to maintain the ink tube of the printer?


● For large format eco-solvent digital printer

Since the eco-solvent ink has a certain volatility, the machine does not need to be easily plugged for a long time. Please follow the steps below to maintain the ink tube of the machine:

1. Before shutting down, please drop the special cleaning solution into the ink stack cap to do a cleaning. Then print the test strip to check that the nozzle is in normal condition. Then put the trolley in the ink stack, put the nozzle height in the low position and shut down normally.
2. It is recommended to print the nozzle test strip every day to check whether the nozzle is clogged. If there is any blockage, please perform the cleaning operation to ensure that the nozzle is in good condition.
3. If your machine has been out of service for more than 3 days, clamp the two ink tubes under the ink cap with clips and add some cleaning solution to the ink cap to ensure that the surface of the nozzle is not wet. Ensure that the nozzle is cleaned once every 3 days.

1. Before the machine is deactivated, print the test strip to check that the nozzle is in the normal state, then place the trolley in the ink stack, put the nozzle height in the low position, and shut down normally.
2. It is recommended to print the nozzle test strip every day to check whether the nozzle is clogged. If there is any blockage, please perform the cleaning operation to ensure that the nozzle is in good condition.
3. If your machine has been out of service for more than 10 days, clamp the two ink tubes under the ink cap with clips and add some pure water to the ink cap to ensure that the surface of the nozzle is not wet.

Why Does UV Digital Inkjet Printer Appear Chromatic Aberration?

UV digital inkjet printers can not only achieve personalized printing, suitable for all sizes of printing, but also can be applied in a wider range of printing, and why UV printers will have color difference, I will introduce it to you today.

1. Picture problem: Before using the UV printer to print a pattern for the media, the operator needs to process the pattern to be printed until the desired effect is achieved, and then the printing will start. However, if we are in the process of image processing, the color of the pattern is damaged due to processing errors, and the printed effect will be greatly different from the actual effect. Therefore, it is best for the printer operator to perform a prototype test before printing until the desired result is achieved before the official print. This saves material and prints product effects that satisfy customers in the shortest amount of time.

2. Ink problem: The quality of the printing ink is the key to directly reflecting the final effect. If the ink quality of the UV digital printer is too poor, it is difficult to print out the effect of the customer's demand. There are many types of UV inks on the market today, so it is difficult to make a decision when purchasing. At this time, the best choice is to contact the printer manufacturer directly, using the special ink recommended by the universal printer manufacturer, which can save a lot of trouble, but also reduce the gap in the printing effect.

3. Printer problem: To print out the customer's demand as quickly and efficiently as possible, the performance of the large format UV printer itself is the most important role in the printer process. A product printed by a high-stability, high-precision UV printer is not easy to appear. The case of chromatic aberration. The higher the printing accuracy of the nozzle used by the printer, the more realistic the effect of printing, and the less the difference between the printing effect and the actual required effect.

What Are the Mistakes In Saving Cost of UV Large Format Printers?

Because the UV large format printer itself and the consumables are relatively expensive, each UV printer user is thinking about how to better maximize the value of the UV printer. So users will save UV printer printing costs in a variety of ways, but often these methods are debatable. There are two major misunderstandings about the common cost savings of UV printers.

1, Cheap is equal to saving

In the hearts of many UV digital printer users, the Cheap and the Savings are equal. In order to save costs, we must shop around and purchase the cheapest consumables. The consequences of this way of thinking are quite serious. It can be said that printing consumables that are obviously lower than the market price generally have problems.

For example, low-cost original consumables are likely to be counterfeit products, and low-cost general consumables are also inferior. Even if you buy fake and shoddy products, there are many specifications for consumable products on the market, including large-capacity consumable products and normal commercial products, as well as small-capacity trial products.

2, Shut down at any time vs long-term boot

In terms of savings, there are two opposite statements, that is, the UV inkjet printer is turned off at any time and turned on for a long time. People who hold the former view believe that the printer should be shut down immediately after use, which saves energy and extends the life of the printer. Supporting long-term startup means that the impact current of each switch will affect the life of the printer. The machine self-test may consume consumables, so the printer should be turned on for a long time, and it can be turned off at most when you get off work.

It should be said that these two arguments have certain truths, but there are also some misunderstandings. The misunderstanding of the use of the switch is to ignore the damage caused by the self-test and the current of the switch, and the printer will warm up when the switch is turned on. Power consumption is much larger than during standby. Therefore, frequent switching machines may not achieve the purpose of energy-saving and life extension.

The misunderstanding of long-term startup is to ignore the impact of standby power consumption and heat on energy-saving and machine life. At the same time, in the long-term standby process, in order to ensure normal printing, the printer will still self-test regularly, and it may still consume consumables.

In order to reduce the printing cost of UV printer, we should seek a balance between the two statements, that is, reduce the number of times the printer is turned on and off. If there is a print task in a short time, it is not suitable to shut down. It is not possible to have a print job within an hour, then shut down, and it is more appropriate to turn it on again when the print job is in progress.

How to Reduce the Error of Digital Sublimation Printer Image Stitching?

Many digital sublimation printer users will encounter incorrect image stitching problems when printing with a wide format printer. What caused this? How should we avoid it?

To solve the problem of stitching images of wide-format sublimation printers, we mainly start from the following three aspects.

1. When you drawing the picture, you need to cut the picture according to the correct size, so as to avoid material waste caused by the splicing error after the picture is drawn. Try to consider the dimensional error after the sublimation inkjet printer prints out. When the picture is cut, if the first picture comes out, the printed picture can be printed without any errors. One thing to note is that the screen should be rotated 180° when printing, starting from the end, in order to prevent errors.

2. Before using the sublimation transfer printer for official printing, first use the drawing software such as Photoshop, CorelDRAW, etc. to import the JPG image into the cut. It is recommended that the gap between the images be kept within 2 cm when cutting. If there is no gap, we can choose a smaller area. Also, avoid cutting out patterns such as text, because the fonts are easy to see and spliced ​​and misplaced.

3. When splicing the screen, be sure to put the output screen first, and then use the splicing machine or related glue to flatten the bean noodles.

Above are 3 advice to help you avoid the image stitching problem, have a try!

Sublimation Digital Printer-Why Ink is Difficult to Dry After Printing Image

After the printing of the picture by the sublimation digital printer, what is the reason why the ink does not dry for a long time? How should it be solved? Today, we will analyze and solve such a problem for you.

There are several reasons why the digital sublimation printer prints pictures for a long time:

First, it has something to do with the quality of the printer's ink.
The quality of the sublimation printer's ink is the most direct cause of the speed of the printed picture. Good quality ink can speed up the drying time of the picture, and the poor quality ink does not have excellent fast drying.

Second, the problem of the heating system of the dye-sublimation printer itself, the heating system of the printer itself helps to speed up the drying time of the picture, so it is very important to choose a good quality printer when purchasing the printer.
Then, if the printer has already printed the image and the ink is not easy to dry, how should we solve it?

There are two solutions to the first situation: one is that you choose a good quality large format sublimation printer ink, which speeds up the drying of the picture. Another way is to help you with a small fan on the side of the picture. Dry. Both methods can solve this problem.

The solution to the second reason is to find the relevant technicians to test. If your heating system is broken, you need to replace the heating system or replace the new one. If there is no heating system, you need to find the manufacturer's technology. The person installs a heating system.
