The problem of nozzle clogging during the use of inkjet printers is mainly based on "prevention". The best way to maintain the best working condition of the nozzle is to do some proper and effective daily maintenance on the nozzle every day, which will greatly reduce the possibility of nozzle clogging.
1. After the installation of the equipment is completed, and the maintenance of the nozzle at the beginning of the equipment is started
1 In order to make the nozzle into the best action state, before the device officially starts working, please be sure to print as many pictures as possible in one to two days. It is best to use all the four colors of CMYK, and add on both sides of the picture C, M, Y, K four-color test strips to ensure that all nozzles are always in the ink-jet state.
2 When spraying, it is best to take out the sponge in the cleaning end of the machine together with its bracket.
Second, how to maintain the nozzle after the daily work is completed
1 Power off the device
2 First clean the moisturizing sponge or plastic wrap with a special cleaning solution, and then pour the cleaning solution on it.
3 Move the head of the inkjet printer back to the cleaning end of the machine and make the nozzle of the nozzle tightly combined with the moisturizing sponge or cling film.
4 Keep this state and let the device stay overnight.
Third, the treatment method after the nozzle is slightly clogged
1 When the nozzle is found to be slightly clogged during the operation of the inkjet machine, it must not hesitate to print, then use a vacuum cleaner or a manual air pump to make the ink spray from the nozzle for nozzle cleaning, and then continue printing after cleaning.
2 Timely and decisive and thorough treatment of nozzle clogging is very important to maintain the best working state of the nozzle during long printing!
3 In addition, it is also necessary to carefully check the condition of the nozzle and find the cause of the nozzle clogging.
Fourth, the processing method when the nozzle clogging occurs frequently during the inkjet printing process
1 First stop the inkjet printer, and then move the head of the inkjet printer to the cleaning position.
2 Keep the power of the device turned on, connect the auxiliary ink cartridge to the float switch signal wire on the carriage of the machine head, and unplug all the signal wires.
3 Pull out the ink supply tube (sub-cartridge end) on the print head, and then use a glass syringe to extract the special cleaning liquid to clean the print head.
4 After cleaning, reinsert the ink supply tube and float switch signal wires, and then continue the previously suspended print job.
Fifth, the above treatment methods have little effect or temporarily no effect
1. Remove the nozzle from the blade nozzle from the nozzle mounting frame and take it out.
2. Pour an appropriate amount of special cleaning solution into a clean glass container. It is advisable to submerge the bottom of the nozzle by 2-3MM after placing it in the nozzle, and then seal the glass container (anti-ash) with plastic wrap and let it stand for more than one day.
Note: Do not touch the cleaning fluid at the top of the nozzle, otherwise it will damage the nozzle.
3. After the spray head is immersed, use an ultrasonic cleaner to oscillate the microwave, pour an appropriate amount of clean cleaning liquid for the spray head into the container of the cleaner, then immerse the bottom of the spray head in the cleaning liquid for about 2-3MM, and then start the cleaner Please select a special nozzle cleaner. If you use a general ultrasonic cleaner, you must strictly control the time. The maximum time cannot exceed five minutes to prevent damage to the nozzle.
Note: Do not use the cleaner for more than three consecutive times.
4. Use a glass syringe to extract the 40ML special cleaning solution, and inject it from the ink supply tube interface on the upper part of the nozzle. Pay attention to observe the state of the water line ejected from the nozzle. If all the water lines are straight, it means that the cleaning is effective. This nozzle You can continue to use it (premise: both the circuit and the piezoelectric crystal are intact). If there is still a part of the waterline sprayed, you must follow the second and third steps to do it a few times. [next]
6. The processing method when the equipment is expected not to be used for a few days
If the equipment is not expected to be used for more than two days, the ink in the nozzle must be cleaned, otherwise the ink in the nozzle will dry due to the gradual evaporation of the solvent, and it may even cause irreversible damage to the nozzle. The processing method is as follows:
1 Turn off the printer power.
2 Move the machine head to the cleaning position, and put a corrosion-resistant container under the spray head to hold the cleaning waste liquid.
3 Use a glass syringe to draw out or pour out the ink in the sub-cartridge directly, then wash the sub-cartridge with a special cleaning solution.
4 Unplug the ink supply tube (from the sub-cartridge) on the nozzle, then use a glass syringe to extract the special cleaning liquid to clean the nozzle. The liquid is inside the spray head, because the cleaning liquid can keep the nozzle warm.
5 Place the treated sprinkler in a clean corrosion-resistant container and seal it up before storing.
Note for inkjet machine operators
1 The inkjet printer is sensitive to static electricity, and the ground wire of the equipment should be handled at one time under the guidance of the installer.
2 When operating the control board or print head, be sure to cut off the main power supply of the printer, and take anti-static measures.
3 The inkjet files in the computer system should be cleaned at any time to ensure that the hard disk has enough space.
4 The inkjet software cannot be used to open other programs or two inkjet programs.
5 During the printing process, files cannot be transferred to the computer that controls the printing machine.
6 The parameter settings of the computer system cannot be changed randomly, especially when the system is reinstalled, the settings must be accurate.
7 The data transmission cables in the energy chain should be checked regularly for wear and tear to ensure that there is no break; short circuit and signal interference.
8 If the printing cloth is too large to move, it will bring horizontal stripes or scraping to the screen, and it will also make the walking size of the printing cloth inaccurate. You can open the printing cloth a little to make the walking uniform.
9 The parameters of vertical step are adjusted in the driver software. For the adjustment method, please refer to the software instruction.
10 The noise of the trolley is increased. Check the wear of the slider or the head and the bearing of the tailstock.
11 Do not push the trolley when the motor is energized. Otherwise, various misalignment phenomena may easily occur.
12 The parameters of the driver have been adjusted at the factory, and the user can not modify it without permission. If the motor fails, please observe the motor alarm signal in detail, and refer to the manual for professionals to deal with.
13 The tension of the timing belt should be appropriate. If it is too tight or too loose, adjust it with the adjustment bolt.
14 Each tube connection of the ink supply system must ensure that there is no leakage. Check whether the ink supply of the ink cartridge is normal, ensure that there is no air leakage at the ink supply tube interface of the nozzle, and there is no air bubble in the ink supply tube.
15 If you find that the inking speed is slow, you must check or replace the filter.
16 The ink should be supplied before the nozzle is powered on, because ink is the main way to take away the heat of the nozzle.
17 Use the cart cover when the inkjet printer is in operation to prevent ink from polluting the nozzle, connection port, nozzle color separation plate, etc., otherwise, it is easy to cause a short circuit accident and damage the nozzle. [next]
Maintenance and maintenance of inkjet printer
The maintenance and maintenance of the inkjet printer is mainly divided into three parts: one is to pay attention to the good use environment; the second is the maintenance for the use of the whole machine; the third is the necessary maintenance of the ink tank, ink and nozzle.
A clean working environment
1 There are precision print heads in the internal structure of the inkjet printer, so avoid mechanical collision and vibration during placement and daily use. The machine should be placed steadily.
2 Because the nozzle nozzle aperture size is equivalent to the dust floating in the space, if the working environment is too poor, it will cause blockage of the nozzle. So keep the environment clean.
3 The working environment temperature of the inkjet printer should not be too high, so as to prevent the mechanical parts and nozzles of the inkjet printer from being corroded.
B Use and maintenance of the whole machine
1 As for the maintenance of the whole machine, it is mainly to ensure the cleaning of the printer, so regular cleaning of the whole machine is a daily required course for users. Due to the intrusion of dust and printing debris in the air, it is easy to damage the fragile main printing parts of the printer and cause printing failures. Therefore, in addition to providing a good working environment, it is also necessary to develop a good habit of cleaning the printer regularly. When cleaning, generally wipe the outside of the machine with clean water to remove deposited dust. Then clean the inside of the printer with a soft brush, a smooth dry cloth or an alcohol cotton ball, and wipe off any dust inside the machine. . . . Note: The main power of the machine must be turned off before cleaning.
2 The bearings and guide rails of the inkjet printer are regularly wiped clean and smeared with engine oil.
3 Periodically replace or clean the filter and ink system. . . . . .
Commonly used nozzle cleaning method
Method for cleaning 128 nozzles:
1 After removing the nozzle, drain the ink inside, and then pour into the cleaning solution to soak for more than ten hours.
2 Vibrate the nozzle with a small ultrasonic wave. With each vibration, use a syringe to draw back from the ink inlet. The vibration time should not exceed three minutes.
3 Do the second step several times in a row, until the cleaning liquid is ejected, and the ink jet closes in a straight line.
4 If the effect is not obvious after ultrasonic vibration, you can let it soak for a longer time, and then repeat the second step.
Cause of plugging
Because the ink of a certain color will not be sprayed for a long time or the temperature of the nozzle will increase, the ink in the static state will dry and agglomerate on the inner wall of the nozzle, and if it cannot be cleaned in time, the nozzle may not be able to be cleaned when the drying degree is relatively strong, so When cleaning the spray head, it is found that the plug is cleaned after production.
Method to prevent spray head
1 The voltage of the spray head is not easy to be too high, to prevent the inner wall from drying due to the heat of the spray head.
2 Ink viscosity is not easy to be too large.
3 The nozzles that do not use a certain color for a long time should be cleaned in time.
4 Protect when you stop spraying
Use and maintenance of spray head
1 Do not touch the socket of the nozzle to prevent oxidation.
2 During installation, the nozzles of the nozzles must be aligned and cannot be hard-plugged. If the pinholes are not properly inserted, the nozzles will not work properly.
3 No ink or cleaning liquid can enter the nozzle socket. The contaminated socket can be cleaned with alcohol.
4 When the nozzle is used, a good heat dissipation environment must be maintained, otherwise the nozzle circuit will be easily damaged.
5 Electrostatic damage to the nozzle circuit is very serious. When operating the nozzle or touching the nozzle card, the operator must eliminate the static factor
6 If the nozzle is broken during the printing process, the nozzle must be suspended for printing. If the nozzle is seriously clogged, the nozzle can be cleaned with cleaning fluid and then the ink is sucked out. Note: The nozzles with serious clogging will cause color difference after cleaning.
7 Use the ink ejection function and cleaning bar function provided by the inkjet program to ensure that all color nozzles will eject ink regularly when printing.
8 After printing, seal the protective film on the surface of the nozzle.
9 Inkjet printers that use solvent-based inks will encounter the trouble of plugging. One of the reasons for the plugging is that after the ink solvent evaporates, the ink particles condense in the nozzle, causing the nozzle to block. The second reason is that there are impurities in the ink, or it reacts with a certain solution to form a foreign body, which is blocked inside the nozzle. The way to prevent it is to use a filter device, the ink cartridge can not enter impurities; often clean the nozzle.
10 Simple cleaning: You can use a soft brush or other liquid dipped in the nozzle to clean the ink outside the nozzle. Use a vacuum cleaner to suck out the residual ink in the nozzle to make the nozzle nozzle smooth.
11 Moderate cleaning: before cleaning, fill the syringe with the cleaning tube with the cleaning liquid; when cleaning, first remove the ink tube, and then insert the cleaning tube into the ink inlet of the nozzle, so that the pressured cleaning liquid enters from the ink inlet tube Nozzle, until the ink in the nozzle is flushed.
12 Deep cleaning: The nozzle of the nozzle is seriously blocked. The nozzle must be removed and cleaned thoroughly. It can be immersed for a long time (dissolve the ink condensed in the nozzle) or cleaned with an ultrasonic cleaner (note that the cleaning time should not be too long to avoid damage to the nozzle circuit), also It can be directly handled by the unit cleaning the nozzle.
13 The nozzle film on the surface of the nozzle is made of polyimide film. Be careful when storing, disassembling, cleaning, and soaking in the nozzle; if it is injured by a hard object, it will cause the nozzle beam to be not straight and affect the quality of the picture.
14 For cleaning the nozzle, use the special cleaning liquid for ink.
15 The clogging of the nozzle is generally the result of long-term accumulation. The user must always keep the nozzle in a smooth state when using it.
16 The nozzle in use should be cleaned regularly and regularly. When the nozzle is not used for a long time, the nozzle can be removed and immersed for a long time. [next]
The method of extending the life of the nozzle of the inkjet printer
In today's low-margin era, how to save every penny and how to make your equipment bring greater profits is a question everyone is considering, but how effective is it? Obviously, extending the service life of the nozzle is one of the means to reduce costs.
One: indoor environment
If the working environment of the indoor equipment is not too good, dust can easily enter the main ink cartridge and then the secondary ink cartridge, and then enter the nozzle, affecting the printing effect of the nozzle and shortening the service life of the nozzle.
Two: operation
The part of the nozzle on the surface of the nozzle can not be rubbed with any object, and the fine hair is easy to hang on the surface of the nozzle. Cause clogging and dripping ink, which affects the printing effect. Therefore, it is also very important to operate the equipment with strict license requirements.
Three: auxiliary accessories
Every accessory on the machine has its purpose, do not remove it at will. Like main ink cartridge, sub ink cartridge, filter, etc.
Four: ink
The quality of the ink directly affects the quality of the picture and the nozzle. It is best to use the ink recommended by the equipment manufacturer, because these inks have undergone rigorous and long-term testing, which guarantees the equipment to the nozzle.
Five: maintenance
The inkjet machine must clean the nozzle before shutting down and power off, and put the nozzle on the moisturizing sea cushion, so as to ensure the same picture quality as the previous few days.
After the machine stops, be sure to apply cleaning liquid to the surface of the nozzle and wrap it with cling film. The cling film is close to the nozzle of the leaf nozzle. This reduces the volatility of the cleaning liquid and ink and extends the service life of the nozzle to a certain extent.
If you do not use the inkjet printer for a long time (such as May 1st, 11th, Spring Festival, etc.), it is best to remove the nozzle from the device, soak it in the cleaning solution, and wrap the container with plastic wrap to prevent dust intrusion and Volatile.
Causes of nozzle clogging
A The ink quality is not close enough, causing nozzle clogging.
B. The rapid changes in temperature and humidity cause damage to the nozzle and the ink and block the nozzle.
C The effect of the nozzle voltage on the nozzle.
D The effect of static electricity on the printer and ink.
E The effect of cleaning method on the spray head-it is recommended to wipe the spray head with a soft sponge or sponge, and do not use ordinary toilet paper.
F The influence of work habits on the spray head-for example, there must be no dirt or hard objects on the mouth of the vacuum cleaner to avoid scratching the spray head during cleaning.
G Ink viscosity is too high-ink viscosity is too high will cause ink to stick in the ink delivery tube, resulting in insufficient ink supply, insufficient inkjet volume, especially in winter, this phenomenon is more prominent.
H Ink viscosity is too low-the ink viscosity is too low, the ink is too thin, the inkjet speed is fast, the ink is reflected on the cloth will be reflected back to the nozzle, causing ink to accumulate on the nozzle, causing the nozzle to block.
