Why does the sublimation inkjet printer’s printhead “strike”?

The printhead is the heart of a wide-format inkjet printer. If there is a problem with the printhead, the entire machine will not work properly. Therefore, be sure to protect the print head when using the printer. So what conditions will affect the normal use of the print head? Today, I will come to give you a glimpse!

First, the airtightness between the ink cartridge, the ink tube, and the printhead.

I have previously talked about the inkjet principle of inkjet printers. Everyone knows that the printer printhead is controlled by the microvoltage change of the negative pressure system to control the ink output. To make the nozzle smoothly ink, it is necessary to ensure the inkjet system. Absolutely sealed. When the voltage is increased, the pressure of the micro-voltage to the ink tube will increase, and a pressure difference will be formed inside and outside the ink tube, and the ink will be pressed from the ink cartridge into the ink tube to the print head. If the inkjet system leaks, the negative pressure system can’t play its due role. If the ink can’t reach the print head, the print head will naturally not emit ink!

Second, the ink cartridge is leaking.

A small amount of air is always present in the upper part of the print cartridge connected to the continuous ink supply system, in order to avoid the phenomenon of ink self-flow caused by the siphon principle. However, if there is an air section in the entire inking line, it is caused by the air leakage of the ink cartridge or the unsealing of the ink injection elbow interface, so the air leakage of the ink cartridge may cause the ink to be discharged or the ink drop.

Third, improper operation.

The ink from the print head ejects ink through its orifice. Since this orifice is small, it may be clogged or damaged with carelessness.

During the printing process, some materials have poor adhesion, and we use a fixing agent to enhance their adhesion. Fixing agent is a very viscous solvent. Once it sticks to the nozzle, the nozzle will be blocked or directly scrapped, which will not work properly.

Fourth, the impact of external factors.

For example, when carrying or using a printer, the machine is hit by an external force, causing the printer to not work properly.

Tips:

1. When using the sublimation inkjet printer, remember to follow the printer instructions strictly!

2. When the printer can’t print normally, don’t panic. Check carefully whether the printer spare parts are in good condition and make other judgments!

Demystifying the reason why the inkjet printer head needs to be cleaned frequently

Friends who often use inkjet printing machines should know that the inkjet printer head of wide format inkjet printers need to be cleaned frequently, so why?

Ink is a volatile liquid that volatizes in the air to clear solids, which is the main cause of nozzle blockage. When the printhead is sprayed on the cloth, a part of the ink remains in the surrounding area. This part of the ink is dried in the air and slowly makes the nozzle hole smaller or even blocks the nozzle hole. But because it is outside the nozzle, it is easy to clean, which is why we often clean the printhead.

How to maintain the inkjet printer head after the daily work is completed?

After all the print jobs are completed every day, in order to keep the print head in optimal working condition and to avoid clogging the printer head due to solvent solvent evaporation, perform the maintenance as follows.

1. Move the handpiece back to the rightmost ink stack area and tightly bond the nozzle to the moisturizing ink stack core.
2. Clean the moisturizing sponge with a special cleaning solution, then pour the cleaning solution onto the sponge to soak it.
3. Turn off the power of the device.
4. Keep this state for the device to stay overnight.

After the printing head is clogged, the treatment method is found:

1. Timely and decisively and thoroughly handling the slight clogging of the nozzle is very important for maintaining the optimal working state of the head during long-time printing!
2. Re-insert the ink supply tube after cleaning, and then continue the previously paused print job.
3. After the printer head is slightly blocked, it is not hesitant to press the pause button to stop printing.
4. Unplug the ink supply tube from the print head, and then use a syringe to draw a special cleaning solution to clean the print head. Method: 40 ml of washing solution was used every 10 minutes, for a total of 3 to 4 times.

How to maintain the printhead after the wide-format photo printer is used up every day?

The normal operation of the wide-format photo printer, in addition to other parts and components without failure, can not be separated from the operator’s careful maintenance and maintenance. There are many details about the maintenance of the photo printer that need us to pay attention to. How to maintain and maintain the printhead after printing the used work every day?

First, turn off the power to the wide-format photo machine. Next, first clean the moisturizing sponge with a special cleaning solution, and then soak the cleaning solution on the sponge. Finally, the equipment unit is displaced back to the rightmost cleaning station and the nozzle is tightly coupled to the moisturizing sponge. It is preferable to keep the large format photo printer in this state overnight. This not only saves power, but also prevents clogging of the printhead. We know that blocking the print head is a very cumbersome thing. So that it will work properly tomorrow and make money for us.

In addition, the wide format photo printer should also be regularly maintained for other parts. Such as ink cartridges, print heads, ink paths, guide rails, regular cleaning of ink stacks, infrared probes, gratings, regular cleaning of waste ink drums, motherboards, etc. Keep the working environment clean and keep an eye on temperature and humidity.

The sublimation printer print head is slightly blocked, how to solve it?

During the heat transfer printing process, it is found that the piezoelectric sublimation printer print head nozzle has a slight blockage, and then press the PAUSE button to pause the print job without hesitation. The ink is then cleaned from the nozzle by a vacuum cleaner or a manual syringe. After cleaning, use a plastic squeeze bottle to spray some cleaning solution onto the nozzle surface to wash away the residual ink. Nanjing ORIC sublimation printer manufacturer specializes in the production of sublimation transfer machine, printer print head blockage problem handling has a coup.

Note: Do not use excessive force when using a manual syringe, otherwise the nozzle will be damaged due to excessive pressure. Timely and decisively and thoroughly handling the slight clogging of the nozzle is very important to keep the nozzle in optimal working condition during long printing times! In addition, it is also necessary to carefully check the condition of the nozzle and find out why the nozzle is clogged.

What should you do if the print head is frequently clogged during sublimation transfer printing?

1. First press the PAUSE button to pause the inkjet job, then press the PURGE button to move the printhead to the leftmost cleaning position.

3. Unplug the ink supply tube (from the secondary ink tank) on the print head, and then use a glass syringe to draw a special cleaning solution to clean the nozzle. Method: 40 ml of washing solution was used every 10 minutes, for a total of 3 to 4 times.

4. After cleaning, reinsert the ink supply tube and level sensor signal lines and continue the previously paused print job.

What if the wide format inkjet printer printhead does not inkjet?

What if the wide format inkjet printer printhead does not inkjet?

When you are using a large format inkjet printer, have you ever encountered a problem with the printhead not producing ink? What if the print head suddenly does not eject ink?

problem causes:

1. The large format printer head has been burned or clogged.

2. Damaged chip with contacts.

Solve the repair method:

1. Separate the contact areas of any three ink heads from the corners of the ink vehicle with clean paper. But do not isolate the wide inkjet printer printhead that is not sure if it is faulty, and do the IC sheet contacts on the ink head accordingly. Observe the performance of the fourth inkjet printer head. If the printing is normal, follow this method. Locate the damaged wide eco-solvent printer nozzle for replacement.

2. Replace the inkjet printer head according to the solution. If the printer printhead still does not emit ink at a fixed location, the contact chip has been damaged and should be replaced immediately.
