The principle of copy paper purchase

Basic purchase principle of copy paper:

1. Paper quality

Printing paper paper can be considered white or colorful. In order to ensure smooth paper feeding, it is necessary to cut the paper cleanly and accurately. You may find that some cheap paper is not accurately cut. The size of the paper may be 2-3mm contrary to the size stated on the package. Just like the paper sold at a low price, it may be full of dust. These problems should be avoided

2. Paper weight

In printing, it is necessary for the paper to pass through a fine paper path. So paper that is too light or too heavy may refuse to enter the printer. As a result, light or heavy paper is usually not suitable for most printers. Will lead to frequent paper jams. Most laser printers are planned to use about 70-90 grams per square meter of paper, perhaps 20-24 pounds in U.S. units. Some laser printers use 60 grams per square meter of paper, but this is an exception rather than a widespread representation.

3. Paper condition

Printing paper all paper is necessary to adhere to clean, wet paper can not be accurately fed, and may be tilted or folded in the paper path. The print quality on wet paper is usually poor. On a laser printer, wet spots may appear vague (or not visible at all). In all cases, the paper should be kept away from dust and dust. Dust and dust may pollute the printer's mechanical equipment. Please use new paper (especially after the printer has been idle for a long time).

4. Paper surface and twists and turns

All paper has a natural tendency to be slender and zigzag, which is due to the fact that the paper is usually stored in a large roll before being cut. The direction of the twists and turns (the opposite side of the preferred printing surface) is usually marked with an arrow on the paper package. Most laser printers require paper to be placed with the paper zigzag side up (printing the other side), which can reduce the possibility of paper failure and paper blocking.
