Many of us may have wondered how a printer works. What exactly happens when you hit “Print”? You may have also wondered why printers sometimes refuse to work, haven’t you?
There’s a key mechanism that does all the heavy lifting, which is called the printhead. It also plays a key role in ensuring print quality. This article answers your questions about printheads and the printing process.
Introduction
Understanding your printer head can save you time and money. Let’s see how. People think of printers as simple machines. They plug them, load an ink cartridge, and begin printing. But it’s not that simple! What happens inside is fascinating—a highly technical printing process is powered and executed by the print head.
The printer head ensures the ink is sent to print on the paper with great precision. For example, if you have a high-end HP printer or a commercial-grade large-format printer, the printhead determines how sharp or precise the output will be when printed. It even governs color accuracy and overall print quality. Most people do not realize that their printers are only as good or bad as their printheads.
How Does a Printhead Work?
An inkjet printer combines science and a bit of magic. Its microscopic mechanism sprays ink in the desired pattern. Depending on the technology, the printhead heats the ink to print or generates vibrations to release the ink for printing.
In this section, we discuss how a printhead works.
Inkjet Nozzle Mechanism
In the inkjet nozzle mechanism, the printhead has several nozzles (maybe thousands) that spray ink droplets onto the paper for printing. This is done precisely in a controlled fashion, without which the printed material will look haphazard and strange. These controlled patterns act like a high-speed, high-precision paintbrush that never messes up a painting (print).
These nozzles operate perfectly to create clean and distinct images or text. The ink ejection is so fast that it’s invisible to anyone watching the printing process. Naturally, people do not know how advanced the tech that makes a printer is.
Controlled Precision
Controlled precision is truly remarkable! The printing method relies heavily on how efficiently and effectively ink is delivered. Did you know the ink droplets these printers deliver are finer than human hair? These are picoliter-sized droplets, which are one-trillionth of a liter.
This printhead is controlled by software and sensors. It adjusts movement and pressure to deliver the right print speed and quality. So, if you want high-resolution images, try the controlled precision printhead.
UV, Solvent, Eco-Solvent & Water-Based Ink Compatibility
Printer models and printing requirements determine the printheads suitable for specific use cases. You can pick a water-based or eco-solvent ink. If you are an outdoor advertising or packaging business, try UV inks.
Each ink type behaves differently and delivers different results based on your printing needs. For example, you need a different printing effect when printing on vinyl banners than when you print a letter on an office letterhead.
So, printing technology is science, but the precision with which the ink reaches the paper is almost like magic. Isn’t it?
Which ink should you choose for your printer, then? You can buy printer ink online to match your printer model and printing process.
Types of Printheads
Different printers require different printheads. Hence, learning about the differences between various printheads can help you choose the right one. Plus, once you know what kind of printhead your printer uses, you can troubleshoot issues independently (like a DIY project).
Let’s study the four main types of printers.
Piezoelectric Inkjet Printheads
These are widely used in professional and industrial inkjet printers because they offer high-performance printing with incredible accuracy. A piezoelectric printhead uses vibrations to eject ink for printing, where piezoelectric crystals act when voltage is applied.
This printhead offers precise droplet size control, leading to high print quality. When your printing job requires accuracy and precision, this is the printhead to rely on!
Thermal Inkjet Printheads
Commonly used in many printers, including HP printers, these printheads use heat to create bubbles that spray the ink onto paper. They are more cost-effective than piezoelectric inkjet printers because they wear out faster.
It is widely used for general purposes because replacing these printheads is affordable and quick. For instance, you can find an HP printhead in almost every place that sells printers.
Continuous Inkjet (CIJ) Printheads
Continuous inkjet printers are great for high-speed applications. They continuously release ink as tiny droplets and spray it into the required patterns using an electric charge. This printing method works well for continuous printing where speed is essential.
For example, if you print packaging labels for various products, a CIJ printhead will ensure continuous ink flow with charged droplets, which will do the required job.
Drop-on-Demand (DOD) Printheads
Drop-on-demand (DOD) printheads improve efficiency and reduce waste by releasing ink when needed. Aptly named drop-on-demand, the printhead will not eject ink unless the printer commands it. Photo printers are known to use this printhead.
How they work is quite interesting! The printhead receives a signal from the machine or controller with instructions on exactly when and where to eject the ink. The ink is then pushed through a nozzle to begin printing. Interestingly, this nozzle could be piezoelectric or thermal (remember the types we studied above).
The Core Component of Every Printer
The core component of every printer is the printhead (we know you guessed it!). It is the heartbeat of the printing process because it controls how prints turn out when something is printed—text or image.
Printer printheads are like your car’s engine. While the vehicle needs many other parts and tires to run smoothly, it cannot function without an engine. Similarly, a printer requires a printer head to perform well. If your printer cannot deliver high-quality prints at the desired speed, the printer head is likely worn out or malfunctioning.
Some key signs of a damaged printer head are:
- Poor print quality (blurry text or unclear images)
- Missing lines or text
- Smudges across printed documents
- Blank spots
- Missing colors
Other signs include strange noises, error messages on the screen, etc.
It is essential to note that regular printer maintenance can help printers function properly over time. Checking ink levels, nozzles, and other settings is necessary for their proper functioning. Plus, cleaning the printhead helps keep your printer healthy and prints refined.
Common Printhead Issues and How to Fix Them
Like any heavily used machine or component, printheads can run into issues. These can be diagnosed and fixed easily when you know what to look for.
Sometimes, you can address these issues independently without seeking professional assistance. Let’s see what these problems are:
-
Clogging: To prevent the adverse effects of clogging, clean the printhead manually. Dried ink can cause clogging. This becomes apparent when you see missing lines, blank parts, or faded areas across your prints.
- Smudges and Streaks: When you see uneven printing, streaks, and smudges, the printhead is likely misaligned. A deep clean and a proper realignment can help resolve these issues. Note that printers have a built-in internal cleaning cycle, but you can consider buying cleaning kits from trusted suppliers to clean your printer.
- Missing or Inconsistent Colors: Color issues usually occur when the ink is incompatible with the printhead. Sometimes, low-quality ink will not deliver good prints, even when the printhead is of a superior make or model. So, using quality ink is necessary for the best printing results. For example, use good STS ink to ensure your prints are consistently sharp and vibrant.
How to Extend the Life of Your Printhead
We all want our printers and printheads to last long, right? So, here are a few expert tips to extend the life of your printer’s printhead:
- Cleaning: You can prevent printhead problems by regularly cleaning the various parts of a printer.
- Software Updates: Updating a printer’s software helps fix bugs and improve performance.
- Regular Usage: A printer’s nozzles may get clogged if the machine is not regularly used.
- Use Appropriate Inks: Low-quality or counterfeit ink can damage even the most superior printheads and printers. Original ink cartridges keep printheads working smoothly. For example, buy quality UV inks to personalize items or products.
- Shutdown When Not In Use: Properly powering off the printer can extend the life of the printhead. Also, avoid unplugging the printer when the power is on.
Regular printer maintenance offers double benefits: it boosts print performance and extends the life of the equipment (all its parts).
