How to avoid paper rubbing fault of photo machine more easily

- Mar 12, 2020-

In the process of printing, if we don't pay attention to the thickness of the paper medium, the flatness of the paper feeding and the adjustment of the height of the nozzle, it is easy to have paper rubbing fault; how to avoid the paper rubbing fault of the photo machine more easily? It's the content that Wuteng photo machine manufacturers share with you today.  


How to avoid paper rubbing failure of photo machine more easily:


1: Correct adjustment of nozzle spacing is too small. As a large-scale wide spray printing equipment for coil media, the photo machine supports different roll media, such as gum, photo paper, spray painting cloth, oil painting cloth, leather, single transparent film, etc.; different spray painting media have different thickness, softness, concave convex surface of consumables, etc. Therefore, when printing, it is necessary to adjust the nozzle spacing reasonably and correctly; if the nozzle spacing is too small, it is easy to rub the nozzle against the paper due to the uneven paper feeding; if the nozzle spacing is too large, it is easy to cause ink flying problems in the ink-jet printing of the photo realistic machine. Therefore, it is better to adjust the nozzle spacing correctly and ensure the height adjustment of the car The thickness of the coin is the best, Wuteng photo machine also provides users with a range of 3mm nozzle adjustable settings.  


2: The high-speed and high-precision ink-jet printing of the paper medium photo machine requires a high-speed and high-precision printing system and printing platform for the paper medium. Smooth and smooth paper receiving and delivery, flat paper feeding platform, etc. can make the photo printing machine more easily avoid paper rubbing fault. Therefore, it is very important to put the paper correctly to avoid the paper rubbing fault of the photo machine.


For example: the paper receiving and discharging system of the photo machine should keep smooth operation and power, keep synchronous paper feeding and receiving speed, and the stable tension between the paper receiving system and the paper discharging system, so as to make the paper conveying more flat and not easy to wrinkle. At the same time, when loading paper, both sides of the printing platform shall be clamped with the press paper, and the air suction system on the platform shall be opened to keep the paper feeding straight and smooth, and close to the platform without arching.  


In addition, it is necessary to pay attention to the problem of long paper output in the ink-jet printing of the photo realistic machine. If the length of the printed output paper is too long, the finished paper pattern is not reeled in time when printing, and the paper is continuously placed downward when printing, and it will stack on the ground. If the paper is not reeled in time, it will block the downward release of the paper, resulting in the paper arching on the platform, and it is easy to hit For printing paper, it is recommended that the user equip the photo machine with a paper reeling system and turn on the reeling system when printing; or arrange the long paper in time when printing the long paper.    


The paper rubbing problem of the photo machine belongs to the common small fault of the daily ink-jet printing, however, the small fault can not be ignored, because the small problem of the photo machine often leads to the damage of the machine, which brings unnecessary loss.


For example, the paper rubbing problem of the photo machine is easy to cause the scratch of the printed output pattern screen and the ink scratch pattern, which will affect the effect of the spray painting image screen and the normal use. It is often necessary to print again, which is easy to cause the waste of the spray painting consumables and affect the production time. The more serious paper rubbing problem is that when the paper medium and the spray nozzle are scratched, it is easy to damage the spray nozzle Surface, resulting in nozzle damage. However, the damage of the nozzle will bring more cost and economic loss, at the same time, it will affect the printing work of the photo machine. Therefore, in the printing process of the photo machine, attention should be paid to avoid the photo machine rubbing paper fault.
