HP Printhead: What It Is and How It Works?

A printhead in HP printers is essential for transferring ink onto paper. Without the printhead, your printer wouldn’t be able to produce the quality prints you expect, making it a vital part of the printing process.

So, how does it work?

The printhead releases tiny ink droplets through nozzles to create sharp images or text. Contacts at the back control the nozzles, ensuring the ink sprays in the right spots for clear, vibrant prints.

There are two types of printheads:

1. Printheads on Cartridges

Where is the printhead on HP printer cartridge? The printhead on HP cartridges is integrated into the cartridge itself, meaning that when you replace the cartridge, you are also replacing the printhead. This design is common in several HP printhead cartridges, such as the HP 45, HP 15, and HP 78.

2. Built-in Printheads

Unlike printheads integrated into cartridges, built-in printheads are part of the printer itself. If you encounter issues with a built-in printhead, you must troubleshoot the printer directly rather than simply replacing the ink cartridges.

Step 1: Turn on your printer and lift the cover to access the cartridge area.

Step 2: Wait for the carriage to move. If it doesn’t move automatically, give it a moment. It should position itself for the printhead replacement.

Step 3: Remove the old printhead cartridge by gently pressing down to release it, then pull it out.

Step 4: Unpack the new printhead cartridge and remove any tape or covers.

Step 5: Insert the new cartridge into the correct slot until it clicks. If your printer has more cartridges, repeat the process for each one.
