How to deal with powder

The so-called "off powder" refers to the phenomenon in which the dust adhered to the printing press vibrates during the operation of the machine to cause the dust to fall onto the printed surface.

Places where flying dust easily sticks

The spout of the dispenser and the nozzle around the spout. There are eight outlets in the full-sheet printer.

In and around the electrodes of the antistatic device arranged in parallel with the ejector.

Part of the ejector is a fan of the small fan and around.

The ejector lifts both sides of the track. When the lifter descends, the track easily sticks to the dust. The more paper is piled up, the easier it is to remove large dust.

In short, it is not a simple matter to develop a dusting machine that is difficult to adhere to the surface of printed matter caused by powder falling. It is not currently possible to completely solve the problem of powder dropping. There is no best way to solve the powder dropping problem except cleaning machinery.

Cleaning place:

Around the spout

Anti-static pipe;

Fans and dischargers throughout;

Both sides of the lift track.

Use an air gun and brush for cleaning.

After cleaning with an air gun, it looks like there is no dust but it will fall out during printing. Therefore, after cleaning, the printer idles at high speed for five minutes to completely drop the dust; at the same time, the glass around the discharger is not attached to the dust. . The number of cleanings is related to the amount of printing time, once a day, and twice a day if it operates continuously for 24 hours. In addition, for the sake of prudence, when PP film coating and subsequent processing are performed, cleaning is first performed to control the amount of scattering.

Avoid dropping powder, suppress flying, use a small amount of powder to solve the back print, and it is easy to clean the hydrophilic UP800.
