How the Ink Jet Printer Works Complete + Pictures

How inkjet printers work - Nowadays, the need for documents has shifted to electronic technology. Printers are used to change the form of soft documents on the computer to hard copies in the form of paper documents.

In general, there are three types of printers used to print documents, namely:

  • Dotmatrix printer, using the principle of an electronic typewriter.
  • Laser Jet Printer, this printer uses a laser beam to scratch a scratch on the surface of the paper.
  • Inkjet printers, printers that use ink to create documents.


So, how do inkjet/ink printers work? Check out the full review in the article below.

Understanding and Functions of Inkjet Printers Ink Jetprinters are printers that use the ink etching method to print



documents. This printer is able to print documents on paperthat has a very large size and the quality is also quite good.

Because of that, Ink Jet printers are the most widely used today. Ink Jet printers have varying resolutions, some are 1200 dpi, some are up to 5760×1440 dpi. This Ink Jet type printer has on demand printing technology. This technology works by spraying small dots of ink on the paper through a nozzle at the tip of the printer needle.

Advantages of inkjet printers


  • Able to produce high print quality and more natural because it uses ink.
  • There is an embossed effect on the document so that it has a fairly sharp color.
  • In terms of price, this printer is also the cheapest printer.
  • The speed is good enough for light performance.


However, there are advantages as well as disadvantages. Even though it has a high print speed, the inkjet is still not able to match the speed of laser printing. So it is not suitable for use on a large scale. Another weakness is the production cost, because it uses ink, we need to prepare a spare cartridge that contains at least three colors of ink. This makes the print price per page higher.

In terms of quality it is quite good, but there are more weaknesses. The nature of the ink fades easily, so that when the document is exposed to a liquid, the ink will fade more easily.

How Do Inkjet Printers Work?


In general, inkjet printers work by channeling ink from the cartridge to the surface of the document through a series of printer needles. This printer needle moves to follow the pattern of the document to be printed. In total there are four stages, namely:

1. Preparation Stage

The preparation stage is a process that begins when an electric current enters the printer. In this phase, the printer will do learning and will look for signals coming from the computer. If the printer driver is already installed on the computer, the printer can immediately recognize the computer.

In this phase, the paper must also be prepared to be filled in the tray. If not, the sensor on the printer will stop the printing process.

2. Setting Stage

The second stage runs where we set which part to print. At this stage we can choose the available print quality, there are high, standard, economy and custom options. Here we can also set whether we will do color printing or monochrome printing. The data that we set earlier will enter the printer controller circuit as a reference in the next stage.

3. Printing Stage

The third stage occurs when we as operators are sure of the settings and choose the print document command on our computer. After we press "OK" on the printer dialog, the computer will send data to the printer via a USB cable in the form of binary numbers. This data then goes to the printer PCB to be decoded.

This PCB will receive all information from the computer and regulate all the movement of the printer head. The PCB will then send a command to the stepper motor which feeds the paper from the tray, and the stepper motor drives the printer head.

After the paper mover stepper receives the command, this motor will pull the paper by turning the roller and the printer head driving stepper also moves the printer head to the right and left according to orders from the PCB with the help of a belt. With the movement of the printer head, the cartridge will issue ink which is channeled to the tip of the nozzle with the help of the PCB.

In the headprint there is also a microchip component that can regulate the movement and expenditure of ink so that it forms the exact same letter as the one on the computer.

4. Completion Stage

The last stage occurs when the entire document has been printed on paper. And the roller will pull the printed paper to the out tray. When all the paper comes out, the PCB will send feedback to the computer to notify that the printing process is complete.

If there is a problem related to the printing process, it will be included in this data so that the computer can display the printing status for the operator to understand.

Inkjet Printer Maintenance Tips


The existence of the printer seems to have become an integral part of the computer, but often we as users do not pay attention to printer maintenance properly. This is what will actually cause problems for our printers, for that, here we will include some easy and inexpensive printer care tips, including:


  • Use the printer periodically at least 2-3 times a week, this aims to keep the ink flowing smoothly.
  • Turn off the printer when not in use or after use. this will prevent the ink flow holes from closing on the printer head.
  • Clean the dirt in the printer at least once every two weeks.
  • Keep the cartridge condition safe and clean
  • If it fails to print, turn off the printer first. Can go through the power socket if the printer is an error.
