Printer general principle fault Overview

Printer general principle fault Overview

Whether working at home or in the unit, printers must be necessary office products. Using printers, We can output office texts, multimedia production results, image printing and other media. Different application fields have different requirements on printer usage and print effects, and also have certain requirements on printer performance. When everyone is using a printer, they also hope that the printer can bring convenience and convenience to themselves. However, many novice users often encounter various print faults when using printers. These faults have brought great trouble to their normal work, is the vitality of the printer so "fragile? Also, in fact, many faults are caused by the operator's lack of understanding of the printer. In addition, lack of understanding of the printer knowledge will make us unable to be dazzled by the printer products, select a printer with high printing speed, low cost and operability! To this end, this article will introduce printer-related knowledge in detail, in order to allow users to truly enjoy the wonderful experience the printer has brought us!

I. Printer development history and market status

Based on different output effects, printers are mainly divided into laser printers, inkjet printers, dot matrix printers, and other special functional printers. For many common users, there are not many opportunities to use dot matrix printers and other special-function printers. Therefore, this article focuses on laser printers and inkjet printers.

Laser printing technology was the most widely used in the 1960s S, and the real investment was applied in the early 1970s S. In the earliest laser printer, the laser transmitter is an electronic laser tube filled with helium-yunqi, which is large in size, so it is subject to a lot of restrictions in practical application. With the emergence of high-sensitivity Photosensitive Materials and the continuous development of laser control technology, the laser printing technology is rapidly mature and put into practical application. On the basis of the electrostatic photocopier technology and the combination of laser technology and computer technology, technicians represented by the United States have successively designed semiconductor laser printers. Compared with needle hitting, the printer not only has good quality, fast output speed, but also has no noise, so it is quickly popularized. After entering 1990s, the output processing speed of the laser printer has reached 8 pages per minute, and the printing accuracy is 600 dpi. It is worth mentioning that HP's resolution enhancement technology and PCL printer language technology have become a general standard for laser printers.

At present, laser printers can be divided into low-speed laser printers Based on the output speed (10 to 10 output per minute ~ 30 pages), medium-speed laser printer (40-40 output per minute ~ 120 pages) and high-speed laser printers (output 130 ~ Page 1 ). Currently, in the laser printer market, the most famous brands include HP, Epson, Canon, limeng, ricang, Panasonic, and Xerox, recently, Lenovo and founder brand laser printers in China also have a certain market share.

Inkjet printers started to appear in early 1990s. They changed the monotonous color of traditional dot matrix printers and brought users into a colorful printing world; however, since the first launch of the spray technology is not completely mature, the cost of various design and development is relatively high, at that time, the inkjet printer is only used in some professional printing systems or advertising design industries. With the continuous maturity and innovation of the inkjet printing technology, the application of the inkjet printer is also expanding, in addition to being used for normal business office and personal office, the "figure" of inkjet printers has begun to appear in the desktop printing system, advertising design system, printing and publishing system, photography and Drawing System fields. Nowadays, the Ink Jet Printing Technology is becoming more and more mature, and its various design costs are also greatly reduced, which makes it possible to quickly popularize it among individual home users.

In recent years, with the increasing number of home computer users, inkjet printers are gradually becoming the first choice for individual users because of their price advantages and good print performance. The current ink jet printer has evolved from its rough effect, slow output, and long time consumption to its current photo-level effect, fast output, and easy operation, in particular, the latest inkjet printer integrates digital functions. This type of printer is very interesting. It can print out a variety of interesting home digital images according to different requirements of print users.

Ii. Working Principle

After learning about the printer development process and the current situation, do you know how the printer works? Let's take a look at the working principles of the laser printer and the inkjet printer!
