Why does the printer print


Principle of operation Printers varies depending on the particular model. Laser, for example, work on the basis of static electricity and a special toner, which is a dry small grains. When they pass through the toner box - they are heated by a laser beam, then appear on the drum inside Printera. Toner collects charged particles and sends a character image to paper that is printed all in one piece. PrinterYou work differently. Most of them use water-based ink. In inkjet Printerah there is a printhead that firstscans the image, and then heats the ink. The desired characters are obtained first on the tape cartridge, and then on paper. The image does not print right away - Printer prints characters gradually, and print speedThe settings of a particular model are influenced. When you want to print a document, you just click on the "Print" button. The printer prints because the computer system has transferred this information to its RAM - the data buffer. You can set tasks in turn or cancel printing using the appropriate settings on the computer, in the program Printera. With the tasks that have been assigned, the technician will figure it out on his own, just keep an eye on the paper in the tray. If Printer does not respond to commands or prints blank sheets, it means there was some kind of failure. It is difficult to determine the hardware failure independently, but if Printer prints blank sheets, it may have endedink. This is easy to understand, if before you noticed that the brightness of the prints falls, or on the paper began to appear bands, or if the print has become poor. If the installed cartridges were "original" Printer will output a corresponding message, if "compatible" - monitor the ink level.
