The working principle of laser printer

The whole process of laser printer work can be said to be charging, exposing, developing, transferring, fixing, cleaning and erasing Wait for the cycle of the seven major steps. The entire laser printing process is carried out by the action of "charging". First, the photosensitive drum is filled with negative or positive charges. The raster bitmap image data in the printing controller is converted into the laser beam information of the laser scanner, and the photosensitive drum is directed through the reflecting prism. "Exposure", the surface of the photosensitive drum forms image information that is exactly the same as the printed image represented by a positive charge, and then adsorbs […]

Maintenance and management of laser printers

1. Choose copy paper correctly Laser printers are used to output paper samples, so first choose paper. It is best to choose electrostatic copy paper. The range of paper is 60-10Sg/square meter. 70g/square meter copy paper is often used. Paper that is too thin or too thick will easily cause paper jam. It may cause mechanical abrasion. It is best not to cut the paper yourself. The cut paper often has burrs and the paper lint accumulates in the machine, which will damage the machine parts and may also scratch the photosensitive drum. Before using the paper, do not put it directly in the paper box. You should make dumplings […]

Factors Affecting Printing Blackness in Laser Cartridge

The toner cartridge of the laser printer assembly plays an important role in the imaging of the laser printer, and it directly affects the blackness of the printing. Several key parts of laser drum: toner, photosensitive drum, charging roller, magnetic roller and scraper. Their corresponding roles are as follows: 1. Toner, as an attachment directly melted on the printing medium, the scientific proportion and fineness of its main components play a decisive role (black toner is available on the market); 2. The photosensitive drum is the core component of exposure imaging, and its photosensitive performance also plays a decisive role in the blackness of the printed product. There is already […]

Print Files with Your Phone

In today's highly developed Internet technology, mobile technology is gradually changing our lives. With the popularity of smart phones, more and more products are inseparable from the support of mobile phone software. As one of the indispensable equipment in daily office, printing equipment has gradually introduced the function of mobile phone printing to users, and the documents in hand can be easily printed out only through mobile WIFI or mobile network. Different brands of printers use different wireless printing methods. Next, let us introduce the wireless printing functions of the four major printers of HP, Canon, Epson, and Brothers. Download the "HP smart" mobile APP in advance Turn on the […]

Why is black color needed for color printing?

1. To reduce the color deviation on neutral colors (grayscale) The imaging method used in the printer is CMYK color system (C-cyan; M-magenta; Y-yellow; K-key). CMYK color system belongs to subtractive color system, that is, the more different colors are superimposed, the darker the color. Eventually CMY will be synthesized into black. But with current technology, CMY cannot be synthesized into pure black, and the final synthesized color is dark gray or dark brown. Therefore, when using color ink to synthesize black, you need to add black ink to make the color more pure. In the same way, when you want to print a dark color, in addition to adding […]

Canon Ricoh provides joint delivery service for multifunction copiers and printers

Due to the growth of e-commerce, Japan has also seen a surge in demand for delivery services, resulting in a shortage of truck drivers. Therefore, Canon and Ricoh, as well as other office equipment companies in Japan, are pooling resources to provide joint delivery services. About 15 office suppliers will test the joint delivery plan in the region by March. The Japan Business Machine and Information System Industries Association (Japan Business Machine and Information System Industries Association) has become a committee responsible for the logistics of making such plans. This organization includes large suppliers such as Canon, Ricoh, Fuji Xerox, Konica Minolta and Kyocera, and sales companies of various manufacturers. […]

Tips for the use of laser printer

The laser printer has been warmed up for more than 2 minutes or the shape is not firm, and the text is off: 1.To consider whether the indoor temperature is above 20℃; 2.To check whether the thermistor has poor contact or failure; 3.To see if the voltage reaches 220V; 4.To see if the paper and toner are too moist.

What will happen to the printer copier in cold weather?

As we all know, printers and copiers use heating to fuse the toner on the paper to achieve fixing. Therefore, many printers and copiers indicate the operating temperature range (usually 10-23 ℃) in the manual. What will happen next? For example, in the winter in our central and northern regions, the general temperature is below 10°C. Using the copier under this temperature environment may cause the following situations: 1. The code generated when the fuser responsible for heating cannot reach the specified temperature within the predetermined time (high probability); 2. Speed ​​reduction caused by unstable heating of the fuser (lower than normal printing speed); 3. Effect problems caused by the […]
