The ink supply system is fundamental to the operation of an inkjet printer. It typically consists of an ink tank, a pump, and a pressure reducing valve.

1. Ink Tank : The ink tank stores the ink required for printing. Depending on the printer’s design, there may be multiple tanks for different colors of ink. It ensures a consistent supply of ink to the print-head.

2. Pump : The pump pressurizes the ink within the tank, enabling it to flow through the printer’s system to the print-head. This pressurization is crucial for maintaining a uniform stream of ink.

3. Pressure Reducing Valve : As the pump pressurizes the ink, the pressure reducing valve adjusts and controls the ink pressure to an optimal level, ensuring that the ink is delivered smoothly.

● Print-Head Assembly

The print-head is the heart of the inkjet printer, responsible for transferring ink onto the print media.

1. Piezoelectric Element : Within the print-head, the piezoelectric element vibrates at high frequencies to oscillate the ink stream. This oscillation breaks the continuous stream into individual ink particles, which are crucial for accurate printing.

2. Nozzle : The nozzle, part of the print-head assembly, is where the ink is discharged in a controlled manner. These tiny openings precisely direct the ink particles onto the paper, contributing to the overall print resolution and quality.

● Ink Particle Control

For precise printing, it is essential to control the behavior of the ink particles after they exit the nozzle.

1. Electrostatic Electrode Plates : These plates apply a negative electric charge to the ink particles. By manipulating the charge, the inkjet printer can control the trajectory of the particles.

2. Electrostatic Sensor : Positioned to monitor the ink particles, the electrostatic sensor ensures that each particle has the proper charge. This feedback loop maintains the accuracy and consistency of the print.

3. Deflecting Electrode Plates : Situated between the electrostatic electrode plates, these plates generate a magnetic field. This magnetic field deflects the ink particles based on their charge, directing them accurately onto the print target.

● Ink Recovery System

Not all ink particles are used in the printing process. The ink recovery system ensures that excess ink is efficiently recycled.

1. Gutter : The gutter collects the ink particles that are not used in the printing process. This prevents waste and reduces the need for frequent ink replenishment.

2. Return Pump : The ink collected in the gutter is retrieved by a return pump and fed back into the main tank. This closed-loop system enhances the efficiency of the printer by recycling unused ink.

● Additional Components

To maintain the optimal viscosity and quality of the ink, some printers are equipped with additional components such as a solvent tank and an auxiliary ink tank.

1. Solvent Tank : The solvent tank supplies a solvent to the main ink tank when the ink becomes too thick. This adjustment ensures the ink maintains the right viscosity for consistent performance.

2. Auxiliary Ink Tank : This tank supplies additional ink to the main tank when needed, preventing interruptions during printing.

Understanding the basic working parts of an inkjet printer, particularly the print-head, can greatly enhance one's appreciation for the technology and mechanics behind these ubiquitous devices.
