With the popularization of office equipment such as printer copiers, paper is already the office supplies that we are exposed to every day. But how much do you know about it? Do you also think that there will be any knowledge on a piece of paper? In fact, the choice and use of paper for office equipment plays a crucial role in our daily office work and office equipment. Office equipment paper is divided into two major categories namely copy paper and printing paper.
First, how to correctly choose and use copy paper
Although copy paper is a copier paper, it has the widest range of applications, and can be widely used in copiers, needle printers, laser printers, inkjet printers, etc., when the output requirements are not very high, especially in the needle printer and Laser printers are more widely used.
Common types of copy paper are: B5, A4, B4, A3 and other four models. Copy paper is the most economical paper for various office equipment. For example, B5 copy paper has 8 boxes, 500 per pack, which means 4000 sheets per box, and the current price of B5 copy paper is 80 per box. -120 yuan, so that the average price of each piece of paper is only 2-3 cents, compared with other office equipment paper (such as some special inkjet printer paper) is very cheap compared.
Copy paper is the most consumed material in an electrostatic copying machine, and is the embodiment of copy quality. Therefore, it is necessary to pay great attention to the correct use of copy paper.
1, the thickness of the electrostatic copier using the thickness of the paper, generally 64-80 grams per square meter, there are copiers can use 50-200 grams per square meter of copy paper.
2. The photochromic paper with a normal surface brightness can have a slightly higher surface luminosity. If it is too smooth, it is not good for fixing, and it is not easy to be cured. According to the requirements of a single adhesive tape can be used (single-sided copy), if there is a double-sided copy of the copier, it is better to use offset paper. White copy paper surface is preferred.
3, the density of the paper The fiber of the paper is fine. Because the fiber of the paper is too thin, the quality of the copying image (ie, the paper separation rate) is affected, and the paper is likely to generate paper dust, paper dust, and dirty machines. In particular, the dirt on the optical part will cause the bottom ash of the copy. Paper is too brittle to break and cause jams, and it also affects the long-term storage of copies and copies.
4, paper hardness and some paper despite the appropriate number of grams, but not necessarily suitable for use in copiers, because: weight and stiffness are two different things, and often due to stiffness is not good, in the transmission process, met resistance slightly Wrinkled. If there are two kinds of paper are 70g per square meter, but the paper fiber structure is soft, stiffness is poor, there is a slight resistance to deform wrinkling often jammed. So only the stiffer (hard) paper can be applied to an electrostatic copying machine.
5, damp paper by wet paper (water content of the paper is too large), due to reduced insulation performance, so the impact of copy quality. Its performance is:
a. It is easy to produce paper jams, especially if it adheres to the photoconductor (drum) and it does not separate, affecting the efficiency of copying.
b. The image, the writing is light and the background gray is big. Such as in the mildew rain season in the south of China, it will not be copied when severe.
c, heating easily deformed.
Therefore, copy paper must be protected from moisture, preferably in a ventilated and dry place. Finished copy paper purchased from the shop (500 packs per pack). Use only one pack and remove it. The order of the paper should not be opened before the cut, and the finished paper must be kept for a stack of plates.
6, paper cutting paper fibers are vertical and horizontal. If the plate is cut in the direction of the fiber, then the long side is "longitudinal" parallel to the fiber of the paper, and the short side parallel to the fiber is "horizontal". Electrostatic photocopying requires that the paper's fiber direction is â€œlongitudinalâ€ because it is good in stiffness, and the paper has a small resistance during operation (the running direction of the paper is consistent with the fiber direction of the paper) and it is not easy to tear.
7. Paper Loading and Discharging The installation of paper in electrostatic copying is a trivial matter, but there is also a certain amount of attention, otherwise it is easy to jam.
A: For semi-circular copy paper, (as the paper needs to make a 180-degree turn), the light of the copy paper should be convex downward, and if it is concave, it is not easy to separate. Horizontally transferred copiers should have the glossy side of the paper facing up.
B: When stacking paper, do not stack the lower half of the upper stack with the upper half of the lower stack in the same paper feeder.
C: Before loading and placing paper, the paper must be fully raked to reduce the adhesion between paper and paper. Methods as below:
(a) Take a stack of paper, squeeze the ends of the paper with both hands, and squeeze it tightly at one end, then pinch it at the other end, then bend it to one side, and then squeeze the paper straight to form a small arc, so that the air enters the gap of the paper. This action is repeated again and again in the other direction (b) Sucking, leveling, and then the knife cut (knife edge) is opened.
(c) Pinch the end of the paper and shake the shredded paper, paper, etc. mixed with it.
Second, how to choose and use the correct paper
1. Paper Quality Paper can be white or colored. To ensure smooth paper feeding, the paper must be cut cleanly and accurately. You may find that some of the cheaper papers are not precisely cut, the paper size may deviate by 2-3 mm from the stated size on the package, and similarly, the cheaper paper may be full of dust. The above problems should be avoided.
2. Paper Weight When printing, the paper must go through a precise paper path. So paper that is too light or heavy may refuse to enter the printer. Therefore, light or heavy paper is usually not suitable for most printers. Will cause regular paper jams. Most laser printers are designed to use approximately 80-90 square meters of paper, or 20-24 pounds in US units. Some laser printers use 60 grams per square meter of paper, but this is an exception and not a widespread phenomenon.
3, paper conditions All paper must be kept clean, wet paper can not feed properly, and may be inclined or folded in the paper path. Print quality on wet paper is usually poor. On a laser printer, wet spots may appear blurred (or not displayed at all). In all cases, the paper should be shielded from dust and dust. Dust and dust can contaminate the printer's mechanism. Be sure to use new paper (especially when the printer has been idle for a long time).
4. Paper surface and curling All papers have a natural tendency to curl slightly because the paper is usually stored in large rolls before it is cut. The direction of the curl (the opposite of the preferred print surface) is generally marked on the paper package with an arrow. Most laser printers require the paper to be curled up (printed on the other side), which reduces the possibility of paper feeds and paper jams.
