Copy paper a copy paper that has been hot pressed

After one copy, the printing paper is heated and pressed, the humidity is significantly reduced, the resistivity is increased, and the residual charge is not easy to escape

(1) The gravity between the paper is increased, so it is inconvenient to rub the paper after being piled up, and the phenomenon of double or multi sheet feeding often occurs.

(2) The high resistivity makes the potential of the paper too high during transfer printing, which makes it more tightly connected with the photosensitive drum, resulting in difficult separation.

Although the conductive brush is used to eliminate electricity when the paper passes through the paper arrangement mechanism, there are always some parts which are not brushed, and the influence of residual charge cannot be eliminated. Copy paper in the automatic double-sided copier, the paper is a single flip copy, there is no problem of sticking. Similarly, in the ordinary copier, it is better to use the manual feeding sheet turnover. If the paper needs to be automatically fed in the carton due to the large number of copies, it should be placed for a period of time to let the residual charge dissipate.

In the automatic duplicator, in order to avoid separation difficulty, the transfer corona voltage is automatically reduced when printing the second side. Ordinary copier can not do this, should open the paper open for a period of time, absorb moisture in the air, can make excessive dry paper to restore appropriate humidity, in order to facilitate separation. Paper stiffness is good, the problem is not big.
