A printer is one of the output devices of a computer that is used to print the results of computer processing on a related medium

。 There are three indicators to measure the quality of a printer: print resolution, print speed, and noise. There are many types of printers,

According to whether the printing element hits the paper, it is divided into impact printer and non-impact printer. By printing character structure,

Divide hologram printers and dot matrix character printers. According to the way that a line of words is formed on paper, it is divided into serial printers and line printers. According to the technology used,

Divided into cylindrical, spherical, inkjet, thermal, laser, electrostatic, magnetic, light-emitting diode and other printers.

1. When encountering sudden power failure, power failure, and the cartridge cannot be returned normally, it is necessary to turn on the machine after the power supply voltage is stable, and the cartridge can be used normally only after the cartridge is returned normally.

This is because the special ink used in the printer has the characteristics of fast drying, in order to prevent the nozzle part of the print head from being exposed to the air all the time when the print is idle, resulting in an increase in ink concentration and air drying, resulting in a "plugging" phenomenon.

Note: When the printer's red power indicator is still flashing, never unplug or cut off the power to the printer.

2. Because the special ink for inkjet printers is affected by factors such as volatility and the use environment, long-term non-use will also cause the printhead to be blocked, so even if you do not use it for a long time, you should turn on the self-test once every other month.

This is because after each normal boot, the printer will calculate the time interval of turning on and off according to its internal clock, and automatically clean the print head according to its length, the purpose of which is also to prevent the nozzle from clogging and not printing normally due to long-term non-use.

3. When the ink runs out, replace the ink cartridge with a new one in time. Because if it is not replaced in time, it is easy to cause the sprinkler to dry up and be scrapped. However, for HP, CANNON and other printers, because the ink cartridge and printhead are integrated,

Replacing the cartridge means replacing the printhead. For this type of cartridge, the service life of the cartridge can be extended by adding ink, and the entire machine will not be scrapped even if the cartridge is plugged. It is worth noting that

If you add ink and do not draw out excess air, there will be no ink ejection during printing.

4. Customize different printing methods. Save ink by choosing to use different ink cartridges, media types, adjust print densities by yourself, and customize print modes.
