Chinese Name: Copy Paper English Name: Copy Paper
Copier paper is the largest consumable material in the electrostatic copier, and it is the embodiment of the quality of copying.
Copier paper is specifically designed for copiers, but its application is the widest, and it can be widely used in copiers, impact printers, laser printers, and inkjet printers when the output effect is not very high. It is especially widely used in impact printers and laser printers.
Commonly used models of copy paper include: B5, A4, B4, and A3. Copy paper is the most economical type of paper for various office equipment, for example: a box of B5 copy paper contains 8 packages, each package has 500 sheets, which means a total of 4,000 sheets in a box. The current price of a box of B5 copy paper ranges from 80-120 yuan, which means the average price per sheet is only 2-3 cents. Compared to other office equipment paper (such as some special inkjet printer paper), it is very cheap.
 
Copier paper is the largest consumable material in a static electricity copier, and it is the embodiment of the quality of copying, so it is very important to pay attention to the correct use of copier paper.
Thickness
The thickness of the paper used in a photocopier generally ranges from 64 to 80 grams per square meter, and some copiers can also use paper weighing between 50 and 200 grams per square meter.
Surface luminosity
General photocopying paper with a slightly higher surface gloss is sufficient. If the surface is too smooth, it is not favorable for the fusing process and may not be easily fixed. For single-sided copying, standard single-coated paper is sufficient. If a dual-sided copying machine is available, then double-coated paper is preferable. The surface of the photocopying paper should be white.
The density of paper
The fiber of the paper should be dense and fine. Because the fiber of the paper is too thin or too coarse, it can affect the quality of the copying image (that is, the paper rate), and it is easy to produce paper hair, paper debris, and dirty the machine. Especially, if the optical part is dirty, it will cause a gray background on the copy. If the paper is too brittle, it is easy to crack and cause jams, and it also affects the long-term storage of copies.
Paper's stiffness
Some papers may have the right weight, but they may not be suitable for use in copiers. The reason is that weight and firmness are two different things. If the firmness is poor, the paper may crease and block if it encounters any resistance during transmission. For example, if there are two types of paper both weighing 70g per square meter, but the fiber structure of one is soft and the firmness is poor, it will deform and crease easily if there is any resistance, often leading to jams. Therefore, only papers with good firmness (hardness) can be used in static electricity copiers.
Paper moisture
Moist paper (paper with too much moisture), due to the reduced insulation performance, can affect the quality of copying. The performance is:
 
a、Easy to produce carding phenomenon, especially when adhered to the photoconductor (drum) and cannot be separated, affecting the efficiency of copying.
 
b. The image, writing, and background are light and dark. If it is severe, it may not be copied in the wet season in southern China.
 
c、Heating can easily cause deformation.
 
Therefore, it is essential to prevent copier paper from becoming damp and to store it in a well-ventilated and relatively dry place. When purchasing pre-cut copier paper (each package contains 500 sheets), it is best to open a new package after using up the current one. For bulk paper, it should not be opened before cutting, and once cut, the sheets should be stacked in a stack per ream.
Paper cutting
The fibers of paper are divided into longitudinal and lateral. If the paper is cut into a flat plate according to the direction of the fibers, then, the long side parallel to the fibers is "longitudinal", and the short side parallel to the fibers is "lateral". Electrophotography requires that the direction of the paper fibers be "longitudinal", as this provides better stiffness, and the paper experiences less resistance during movement (the direction of paper movement is consistent with the direction of the paper fibers), making it less prone to tearing.
Paper Folding
In the process of electrostatic copying, the placement of the paper is a minor matter, but there are certain requirements, otherwise it is easy to cause paper jams.
 
A: For the semi-circular conveyor of the copy paper, (because the paper needs to make a 180-degree turn), the light convex side of the paper should be facing down, as the concave side is facing down, it is difficult to separate. For the horizontal conveyor of the copy machine, the light side of the paper should be facing up.
 
B: When taking paper, it should be stacked, and the lower half of the upper stacked paper and the upper half of the lower stacked paper should not be put into the same supply paper box together.
 
Before loading or placing the paper, it is necessary to fully twist and twist the paper to reduce the adhesion between the paper. The method is as follows:
 
(a) Take a stack of paper, hold both ends of the paper with both hands, one end to be tightly held, and the other end to be relaxed, then bend one way, then tightly pull the paper straight to form a small arc, allowing air to enter the gaps of the paper, and then repeatedly do this in the opposite direction.
 
(b) Gather and smooth, then pull apart the cut portion (the knife edge).
