It contains tiny nozzles that precisely deliver ink droplets, creating the images and text you print. Over time, these nozzles can become clogged with dried ink or debris, leading to print quality issues.

Before you embark on a printhead replacement, it’s essential to confirm that the problem lies with the printhead itself. Look for these common signs:
- Streaks or banding: Horizontal lines or streaks appearing on your prints, often in a specific color.
- Missing colors: Certain colors are not printing at all, or they appear faded.
- Printhead error messages: Your printer might display error messages related to the printhead.
- Noisy printing: Unusual sounds coming from the printer during operation, potentially indicating a faulty printhead.
