How to maintain uv flatbed printer in summer hot weather?

In summer, both temperature and humidity will increase dramatically. People need to prevent heat stroke and summer heat. And our equipment needs to be maintained in the hot sun.In this issue, based on years of experience, I shared five ways to maintain a UV flatbed printer in the summer.

uv flatbed printer

Method 1: Temperature control.

The uv flatbed printer should be placed in a cool, backlit corner to avoid high temperatures and direct sunlight. Suitable indoor temperature is 19 ° C ~ 32 ° C, humidity is 25% ~ 70%.

Method 2: Power off and moisturize.

When uv flatbed printers do not work for a long time, you can choose to moisturize after power off, do not let the machine exit the standby state, so the temperature will rise.

Method 3: Always check the print head.

After turning on the wide-format uv flatbed printer every day, be sure to test the strip first to see if the sprinkler is clogged. The summer temperature is too high and the ink is easy to dry.

Method 4: Clean the uv flatbed printer weekly.

Once a week, clean the inside and outside of the equipment. Especially in key locations such as noses and rails, it is especially important.

Method 5: The position of the flat line must be viewed daily when it is turned on.

Make sure that the surface of the print head line is clean and that the connecting rod is tight and not loose.

How to save ink with a large format dye sublimation printer?

Large format dye sublimation printer is inkjet printing, which we all know, so ink is an indispensable part. Saving printing ink is also a manifestation of profitability.

How can I save digital printing ink during the printing process of large format dye sublimation printer, and what are the techniques for saving ink?

large format dye sublimation printer

Here we briefly introduce:

1. Set the print mode correctly. In general, the text we print does not need to be very detailed, as long as it can be seen clearly. We can use the print mode flexibly before printing, which can effectively save ink. There are many options for the print mode. The finer the print quality, the more ink it consumes. So for a typical print job, choose the production mode.

2. Use all the ink cartridges. When printing, usually about 20% of the remaining ink cartridge will indicate insufficient ink, reminding you to replace the ink cartridge. In this case, we can ignore it and continue the print job until the last drop of ink is finished.

3. Use the cartridge protection card to save. Some brands do not have this protection card, and some brands have this feature. If you buy a device, it will come with a card that holds the ink cartridges (some common cartridges are also available), so we should be good at it. Because the wide format sublimation printer is not used for a long time, the ink in the cartridge is easily dried, especially in a dry environment. If you don’t use a digital printer for a long time, you can take the cartridge and put it in the card, and put it in a sealed plastic bag as much as possible to slow down the ink.

4. Minimize the number of switching machines. Minimize the number of switching machines, and collect the fragmented file printing tasks together to print, which can save ink consumption. Because the digital printer starts up each time, it initializes the printer and automatically cleans the print head and inks the ink delivery system, which requires a large amount of ink. Therefore, you should try to put the print jobs together for printing, and do not turn the wide format inkjet printer on and off at will.

The above small methods of summing up hope to help everyone. If you have any questions about the use and maintenance of the ink sublimation printer, please leave a message below. Today’s article is here, thank you for browsing.

What are the methods to prevent static electricity in eco solvent printers?

When they are using eco solvent printers will appear static electricity. What are the ways to prevent static electricity from the printer? Let me introduce you to the following.

eco solvent printers

At present, there are three main methods of controlling static electricity:

1. Ground the printed material;

2. Use electrostatic paint or detergent, etc.;

3. Ionize the air around the static-charged material.

However, in actual operation, it is not realistic to ground the material. The use of antistatic coatings and cleaners inevitably adds significant cost. There is also a lot of inconvenience in ionized air.

eco solvent printers

To be scientifically anti-static in eco solvent printers, you need to do:

a. Control the printing speed. Studies have shown that after the speed is reduced, the electron cloud is in a stable state, the electrons are not released, and the probability of generating static electricity is the lowest.

b. Control room temperature and humidity. In general, in the range of 35%-65% relative humidity, the static electricity on the printed material is more easily removed without affecting the ink droplets on the wide printer head, ensuring printing accuracy. It is recommended that the office be regularly ventilated to ensure good ventilation.

c. Ground the eco-solvent printer.

d. Do not use ink with too high viscosity. Although the weight of the ink droplets is too large to reduce the influence of static electricity, too much viscosity will bring disadvantage to the crystal of the printer head.

The above is the way to prevent static electricity when I use the wide-format eco solvent printer. I hope that today’s sharing can help you better use the printer.
