With the resurgence of the national resurgence of work,printers around the country began to print busy. It is very annoying if the printer has a firing tilt problem at this time. If you want to avoid these problems,it is important to understand the reason for the firing tilt of the priner and how to deal with it.
We has sorted out the technical problems about the firing tilt of the printer's drawing to help you quickly deal with the failure. Six common reasons for the firing tilt of the printer:
1. Uneven bearing
2. The pressure plate is damaged or deformed
3. The decoder is loose or malfunctioning
4. The encoder strip is damaged
5. The motor is damaged
6. The carriage board is faulty
The processing method of the firing tilt of the printer: first check whether the bearing is balanced and whether the pressure plate is damaged or deformed; then check whether the decoder and encoder strip are damaged or faulty,and finally go to the motor and the carriage board to check these important parts . Check step by step according to a certain process,not only can quickly find the cause of the problem,but also quickly deal with the problem.

Why is the head clogged? When the ink is sprayed,the nozzle of the machine does not emit ink,which causes the lack of color in the picture content. It is usually called "nozzle clogging",which is the main factor that affects the quality of the picture and the yield. Of course,there are various reasons for "clogging". Let's take a look at the introduction:
1. After the ink accumulates to a certain degree,the nozzle will block the nozzle hole on the outside: it is the most common way of clogging,because the solvent in the ink must be volatilized into the air to dry the picture,so the ink is a volatile liquid. The air is easily volatile and clears solids. When the nozzle is spraying on the fabric,there will always be some ink left around. This part of the ink will slowly become smaller and even block the nozzle after drying in the air,but because it is outside the nozzle,it is easy to Clean up,this is why we often clean the nozzle.
2. The piezoelectric crystal is damaged: it is certain that the nozzle can not eject ink. The general piezoelectric nozzle can be used for about one year. It may be normal to use it in a factory with a lot of inkjet workload for less than one year.
3. Fatigue damage of piezoelectric crystal: the phenomenon is that the nozzle sometimes ejects ink,sometimes the ink cannot be ejected,especially when the inkjet volume is large (ie when spraying a dark screen),the phenomenon of "clogging" is obvious,and the best method at this time is to replace A new nozzle.
4. The clogging of the filter in the nozzle causes the nozzle to not produce ink: use the nozzle for a long time,especially in factories where the printing task is not full and often shut down at night,the ink does not flow in the nozzle for a long time,and it is easy to be absorbed in the internal filter On the wall of the net or ink channel,making the cross-sectional area of the ink flow smaller will also cause the ink phenomenon of the nozzle. Now special equipment can help you solve this problem of the nozzle.
5. The viscosity of the ink is too high or too low: the viscosity of the ink is too high to make the fluidity of the ink poor,the amount of ink ejected by the nozzle per unit time is not enough; the viscosity of the ink is too low,that is,too thin,easy to press in the nozzle hole Transistor sucks in air when pumping back,and cannot suck ink,so the air is ejected; both will cause the phenomenon that the nozzle does not output ink.
6. The failure of the drive circuit: The aging of the electronic components of the drive circuit and the accumulation of too much dry ink dirt may affect the voltage of the drive nozzle,resulting in no ink or unstable ink output.
7. Types of ink: Some manufacturers' inks are improperly controlled due to the amount of desiccant. The drying is too fast,which can easily cause the ink to block externally. Although it can be cleaned,the cleaning interval is relatively frequent. Once the nozzle is not used for a long time,it is not timely. When protecting the print head,it may cause permanent damage to the print head the next time it is sprayed.
8. Frequent ink replacement: In many cases,when the ink is replaced,the nozzle may not be well protected,which may affect the inkjet state of the nozzle.
9. Environmental temperature and humidity of the device: the general recommended temperature is 22~25 degrees,the humidity is 40~70%,the high and low temperature affect the viscosity of the ink,and the nozzle will lack ink or paste,which is often mistaken Think "spray head clogged".

It is relatively common for the print head to be blocked for a long time after the use of the printer. Let's take a look at what causes the print head to be blocked? Generally,the clogging forms of print head are hard clogging and soft clogging,collectively referred to as hard faults and soft faults; common causes of clogging: such as clogging failures that occur easily when there is no printing operation for a long time. Because the print head is not properly sealed after being printed properly or placed for a long time,the water is excessively evaporated,causing the ink particles to dry up at the tip of the fine print head,which prevents the ink from being ejected normally; or the different inks are mixed and used to produce a chemical reaction,Usually manifested as faults such as broken lines,missing colors,unclear writing or even unable to print normally. During normal use,each ink pipe is ventilated. The ink supply system uses the principle of siphon,and a small section of air is always present on the continuous supply ink cartridge,which is to cause the phenomenon of ink self-flow. If you see some small air in the ink pipe,don't worry,this is normal. The air layer on the ink cartridge expands and contracts with the change of the indoor temperature. When the printer is not in use,for example,an air segment of no more than 15 cm appears on the ink pipe at the print cartridge interface. This is caused by the expansion of the air. . But if there is air in the whole section,it may be caused by the air leakage of the ink cartridge or the leak of the elbow joint or the broken elbow. If the entire length of air appears in an ink pipe,check the seal between the ink injection elbow and the print cartridge interface. The elbow can be removed for inspection and reinstalled. If the entire length of air appears in each ink delivery line,check the ink outlet of the print cartridge for air leaks or replace it with a new cartridge.

Although the UV flatbed printer is convenient,quick,and one-time forming,it is environmentally friendly,but the UV flatbed printer is also more expensive than the general machine. How to maintain such a precious machine. We explain to you:
1. Make sure the surrounding environment of the UV flatbed printer is clean. Too much dust in the working environment can easily lead to poor lubrication of the guide shaft of the cart,which hinders the movement of the printing nozzle during the printing process,causing inaccurate printing position or impacting the mechanical frame to cause damage and crash. When the print head does not return to the initial position and restarts,the UV flatbed printer will first return the print head to the initial position,and then will perform the cleaning operation of the print head,so it will cause unnecessary waste of ink. The way to solve this problem is to often wipe off the dust on the guide shaft and lubricate the guide shaft.
2. Make sure that the UV flatbed printer has a stable working platform,and do not place anything on top of the UV flatbed printer. The front cover of the inkjet printer must be closed during operation to prevent dust from entering the machine or other hard objects to hinder the movement of the inkjet printer cart. It is forbidden to plug and unplug the printer cable while it is live,as this will damage the inkjet port of the inkjet printer and the parallel port of the PC,and may even damage the motherboard of the PC. If the printout is not clear,you can use the printer's automatic cleaning function to clean the print head,but it will consume a small amount of ink. If printing is still unsatisfactory at http://www.xaar-uv.com after several consecutive cleanings,the ink may have run out and the ink cartridge needs to be replaced.
3. Before turning off,return the print head to the initial position (when the UV flatbed printer is in the pause state,the print head automatically returns to the initial position). In this way,one is to avoid the waste of ink when the UV flatbed printer restarts the cleaning operation of the nozzle at the next startup,and the second is because the nozzle can be sealed by the protective cover at the initial position,so that the nozzle is not easily blocked.
4. When the ink cartridge is not used for a long time,it should be placed at room temperature to avoid direct sunlight. Because the ink evaporates quickly in this environment,it is easy to cause nozzle clogging. In addition,in the low temperature and humid environment,the print nozzle circuit and ink are prone to problems.
5. When replacing the ink cartridge,be sure to follow the steps in the operation manual. Pay special attention to the above operations when the power is turned on. Because after replacing the ink cartridge,the UV flatbed printer will charge the ink delivery system,and this process will not be able to be performed when the power is off,and the UV flatbed printer cannot detect the reinstalled ink cartridge. In addition,some UV flatbed printers use the electronic counter inside the inkjet printer to measure the ink capacity (especially in the statistics of color ink usage). When the counter reaches a certain value,the UV flatbed printer determines that the ink is used up . During the ink cartridge replacement process,the printer will reset its internal electronic counter to confirm that a new ink cartridge is installed.
6. In addition,the grating bar of the UV flatbed printer must be well protected. Do not touch it with your hands or let it be contaminated with dust to prevent inaccurate positioning.

About the service life of the UV printer is closely related to the correct operation. Whether it is an ordinary printer or a UV printer,more or less failure problems may occur during the operation of the machine with little attention,which also adds a lot of trouble to the use process . But pay more attention to some details in normal use,which can effectively avoid many failures,and make UV printers more convenient and effectively improve the printing speed and effect. Place the UV printer on a horizontal ground: Due to the UV printer’s unique way of working,the place where the UV printer is placed must be a flat ground. Inclined and uneven ground will affect the printing effect,slow down the nozzle speed,and thus affect the overall Print speed. If it is not handled properly,the serious one will damage the internal structure of the machine. Try to place the UV printer on a flat and smooth floor,and keep the surroundings hygienic and clean to prevent dust or foreign objects from rising into the machine. Do a good job of cleaning the UV printer: the exterior and interior of the UV printer should be cleaned regularly,do not wait until a thick layer of dust accumulates,and then remedy the problem. The outside of the UV printer can be scrubbed with a soft cloth dampened with water. The cleaning liquid must be a neutral substance such as water. Never use detergents containing alcohol. The interior mainly refers to the nozzle,ink system,etc.,these parts need special cleaning agent and cleaning method. For the dust on the surface,try to use a dry cloth. When cleaning important parts such as the nozzle,be sure to follow the instructions given by the manufacturer,or ask the manufacturer's after-sales personnel to clean. UV printers should avoid heavy stress: UV printers,like other household appliances and equipment,should avoid heavy stress. Some customers will place other objects on the platform of the UV printer,which is very likely to crush the UV printer shell,platform,etc.,and some small things will fall into the printer. Drinks and tea cups are prohibited products,and liquids are strictly prohibited to prevent liquids from entering the machine and causing irreparable losses.

There may be various failures when printing pictures on a printer,but among them,the depth of the picture is the most ultimate problem. When the printer encounters the depth of printing,there are several ways to further solve or alleviate the problem.
1. Change feathering to decentralized mode
2. Update the software,replace with new software,and then recalibrate
3. Adjust the print head parallel,adjust the ink sequence and change the curve
4. Adjust the heating before,after,and at the same time adjust the feathering mode

The printer often encounters various unexpected glitches. For many people,the most troublesome one is burning the nozzle. As the core part of the photo machine,the print head is very expensive. Once burned,it will inevitably increase the production cost. Secondly,the burnout of the print head will also slow down the printing progress of the order and affect the work efficiency.
    This article summarizes some of the reasons that are easy to cause the printer to burn the print head. You can briefly understand it and evade it according to the basis.
   1. Ground wire. The main purpose of the grounding wire is to prevent the accumulation of static electricity in the machine itself. Once excessive static electricity is difficult to discharge from the body,it will cause problems such as burning print head and board.
   2. Voltage and current overload. This kind of situation occurs in the peak period of electricity consumption,especially in summer,please be sure to install a 5000W voltage regulator to prevent it from happening.
    3. Switch on and off frequently. The current at the moment of start-up has an impact on the machine itself. Frequent switching on and off will only increase the burden on the print head and even burn it. The recommended interval is five minutes.
    4. Print in low ink state. During the printing process,the ink is used up. If you do not add ink in time,the print head will be burned out for a long time,and the print head will burn out,so you need to add ink in time if you find that the ink is insufficient!
    5. High temperature. The main performance is: long time overload operation or room temperature is too high,it is recommended to print in the state of ambient temperature 15 ℃ ~ 30 ℃,humidity 35% ~ 65%.
    6. The board has ink. The ink used in the printer has a certain degree of corrosivity. Dropping on the board will not only cause corrosion,but also cause problems such as short circuit and burn-in problems.

The UV flatbed printer suddenly appear lines when printing materials,which is a problem that may occur for many users and models,especially some UV flatbed printers that have been produced for a long time are prone to appear. In addition,users often display normal tests,Baige tests,and wireframe tests. However,when they are printed again,they often cause headaches. This may be caused by improper operation and poor software settings. We have summarized the causes and solutions of several kinds of UV flatbed printers,and hope to be able to solve the puzzles for everyone.
1. The Print head of the UV flatbed printer is clogged; digital printing is dot matrix printing,which consists of dots of a certain density (DPI) to form a pattern. Therefore,any one orifice is blocked. There will always be a blank line in the direction of tile movement,so-called white brushing. Especially when encountering abnormal ink or using a non-circulating head,this phenomenon is easy to appear. The main reasons for the general clogging of the orifice are: the design of the ink supply system is unreasonable,and the ink flow in the system is dead and precipitates: the ink has poor stability,and it is denatured and aggregated during use; dust,water vapor and other pollutants are contaminated from the outside,The clogging of the spray holes can generally be solved by external cleaning.
2. The oblique jet of the spray hole of the UV flatbed printer; the so-called oblique jet means that the ink dot can come out. In this way,a white line appears where it should be sprayed,and a darker line appears next to it. The reasons for the slant are: problems in the ink supply system or the ink itself,which causes the nozzle to be in a semi-clogging state,causing the spray point to be offset; the parameters of the nozzle (voltage,waveform curve,etc.) are set unreasonably; the performance of the ink does not match the requirements of the nozzle.
3. The overlap between the nozzles of the UV flatbed printer; the overlap between the nozzles is a common phenomenon that produces drawing. It is characterized by a wide brushing width. Generally between 1~2mm,and sometimes there is no. The main reasons are: poor handling of the drawing points between the nozzles. Make the position always appear dark or light line; the belt appears in the process of running in the printing area. Even if it is only a few millimeters,there will be obvious dark or light or white (exposed background) lines. In this case,the brushing usually occurs sometimes,or appears at a local position of the brick. When this happens,it can only be solved by improving the running accuracy of the belt or shortening the printing distance between the colors as much as possible in the design.
4. Bubbles appear in the nozzle of the UV flatbed printer; the drawing caused by bubbles in the nozzle generally causes the printed artwork to appear meteor-like blank,with a width of 2~3mm or more. The length is from a few millimeters to tens of millimeters,sometimes Sometimes none. This phenomenon can only be solved by improving the ink supply system or adjusting the parameters such as ink filling and exhaust.
5. The drawing caused by the deposition inside the nozzle of the UV flatbed printer; the drawing caused by the deposition inside the nozzle is sometimes dark,sometimes light,and appears in a certain area. And it will be more serious when printing dark products. Generally,it is common in non-circulation sprinklers,especially when the shutdown time is long. The ink in the nozzle is ejected through the off-time mode. The possibility of ink deposition in the nozzle can be reduced,but if it occurs,it can only be handled by a large amount of inkjet or cleaning the nozzle with clean water. Or take the uv flatbed printer nozzle calibration method as follows: launch the printing program in the computer,select the printer in the printing program,then click the right mouse button,select protection,print nozzle calibration,the machine will actively proofread the job,and repeat the operation several times,You can effectively improve the printing effect.

The Printer has a very important effect in the office and advertising industry. What happens when a blue screen appears during use? What should I do?
The way to deal with blue screen failure of printer
1. Perhaps the memory module is damaged. Try change a new one.
2. It may also be caused by a short circuit after the data cable is worn,so try to exchange a new data cable to see if it is normal.
3. Insert the cable again.
4. Restart the printer to see if it can handle the doubt.
5. Check if the mainboard is damaged. If it is damaged,you need to exchange a new mainboard.

Electronic items are very fragile,as the main board of the printer. Why is your printer board easy to burn out? Let's talk about it for everyone.
1. Maintain a stable voltage when using the photo machine.
2. The printer's own power supply cannot adjust the voltage,causing the machine to short circuit and burn the motherboard.
3. The circuit cable connected to the head is not connected properly,causing the mainboard to burn out.
4. The electrolyte inside the machine can not decompose some bad ink,causing burnout of the nozzle and burning of the motherboard.
5. The voltage is too high,the stable voltage is not maintained at 220 voltage,resulting in burnout.

Various problems will occur when the printer is used for a long time. Will the temperature affect the printer? Let's talk about this question.
The printer often has some false plugging phenomenon,that is,because the temperature of the ink is reduced,the viscosity becomes strong,and if the viscosity is too strong,the ink will break during the printing process,and it will return to normal after the head is cleaned,but it will reappear soon. This situation. Some users mistakenly believe that this is a problem with the print head,which is not ture. In order to better maintain the normal working state of the printer,pls take care the space environment and temperature of the printer working workshop.
For advertising companies,the temperature and humidity of the printer workshop affect the inkjet printing process to a certain extent. For example,when the temperature of the printer workshop is relatively low and relatively cold,the fluidity of the ink of the printer is weakened,so it is likely to stay clogged in the nozzle hole and appear as a broken line on the screen.
However,this is a common failure of the printer in cold and low-temperature climates. Generally,this situation is mostly affected by the low temperature in the workshop of the printer,that is,the nozzle is falsely blocked,that is,the individual nozzles of the nozzle are not smooth or not at all. Under such circumstances,it is easy to affect The normal inkjet printing status of the printer and the image quality and effect of the image.
